Playwright文档 - Page(页面)


Page 提供了与浏览器中的单个选项卡或Chromium 中的扩展后台页面进行交互的方法。一个浏览器实例可能有多个页面实例。

class: Page

  • since: v1.8
  • extends: [EventEmitter]

Page provides methods to interact with a single tab in a [Browser], or an extension background page in Chromium. One [Browser] instance might have multiple [Page] instances.

This example creates a page, navigates it to a URL, and then saves a screenshot:

1const { webkit } = require('playwright'); // Or 'chromium' or 'firefox'. 2 3(async () => { 4 const browser = await webkit.launch(); 5 const context = await browser.newContext(); 6 const page = await context.newPage(); 7 await page.goto('https://example.com'); 8 await page.screenshot({ path: 'screenshot.png' }); 9 await browser.close(); 10})(); 11
1import com.microsoft.playwright.*; 2 3public class Example { 4 public static void main(String[] args) { 5 try (Playwright playwright = Playwright.create()) { 6 BrowserType webkit = playwright.webkit(); 7 Browser browser = webkit.launch(); 8 BrowserContext context = browser.newContext(); 9 Page page = context.newPage(); 10 page.navigate("https://example.com"); 11 page.screenshot(new Page.ScreenshotOptions().setPath(Paths.get("screenshot.png"))); 12 browser.close(); 13 } 14 } 15} 16
1import asyncio 2from playwright.async_api import async_playwright, Playwright 3 4async def run(playwright: Playwright): 5 webkit = playwright.webkit 6 browser = await webkit.launch() 7 context = await browser.new_context() 8 page = await context.new_page() 9 await page.goto("https://example.com") 10 await page.screenshot(path="screenshot.png") 11 await browser.close() 12 13async def main(): 14 async with async_playwright() as playwright: 15 await run(playwright) 16asyncio.run(main()) 17
1from playwright.sync_api import sync_playwright, Playwright 2 3def run(playwright: Playwright): 4 webkit = playwright.webkit 5 browser = webkit.launch() 6 context = browser.new_context() 7 page = context.new_page() 8 page.goto("https://example.com") 9 page.screenshot(path="screenshot.png") 10 browser.close() 11 12with sync_playwright() as playwright: 13 run(playwright) 14
1using Microsoft.Playwright; 2using System.Threading.Tasks; 3 4class PageExamples 5{ 6 public static async Task Run() 7 { 8 using var playwright = await Playwright.CreateAsync(); 9 await using var browser = await playwright.Webkit.LaunchAsync(); 10 var page = await browser.NewPageAsync(); 11 await page.GotoAsync("https://www.theverge.com"); 12 await page.ScreenshotAsync(new() { Path = "theverge.png" }); 13 } 14} 15

The Page class emits various events (described below) which can be handled using any of Node's native EventEmitter methods, such as on, once or removeListener.

This example logs a message for a single page load event:

1page.once('load', () => console.log('Page loaded!')); 2
1page.onLoad(p -> System.out.println("Page loaded!")); 2
1page.once("load", lambda: print("page loaded!")) 2
1page.Load += (_, _) => Console.WriteLine("Page loaded!"); 2

To unsubscribe from events use the removeListener method:

1function logRequest(interceptedRequest) { 2 console.log('A request was made:', interceptedRequest.url()); 3} 4page.on('request', logRequest); 5// Sometime later... 6page.removeListener('request', logRequest); 7
1Consumer<Request> logRequest = interceptedRequest -> { 2 System.out.println("A request was made: " + interceptedRequest.url()); 3}; 4page.onRequest(logRequest); 5// Sometime later... 6page.offRequest(logRequest); 7
1def log_request(intercepted_request): 2 print("a request was made:", intercepted_request.url) 3page.on("request", log_request) 4# sometime later... 5page.remove_listener("request", log_request) 6
1void PageLoadHandler(object _, IPage p) { 2 Console.WriteLine("Page loaded!"); 3}; 4 5page.Load += PageLoadHandler; 6// Do some work... 7page.Load -= PageLoadHandler; 8

event: Page.close

  • since: v1.8
  • argument: <[Page]>

Emitted when the page closes.

event: Page.console

  • since: v1.8
  • langs:
    • alias-java: consoleMessage
  • argument: <[ConsoleMessage]>

Emitted when JavaScript within the page calls one of console API methods, e.g. console.log or console.dir. Also emitted if the page throws an error or a warning.

The arguments passed into console.log are available on the [ConsoleMessage] event handler argument.

Usage

1page.on('console', async msg => { 2 const values = []; 3 for (const arg of msg.args()) 4 values.push(await arg.jsonValue()); 5 console.log(...values); 6}); 7await page.evaluate(() => console.log('hello', 5, { foo: 'bar' })); 8
1page.onConsoleMessage(msg -> { 2 for (int i = 0; i < msg.args().size(); ++i) 3 System.out.println(i + ": " + msg.args().get(i).jsonValue()); 4}); 5page.evaluate("() => console.log('hello', 5, { foo: 'bar' })"); 6
1async def print_args(msg): 2 values = [] 3 for arg in msg.args: 4 values.append(await arg.json_value()) 5 print(values) 6 7page.on("console", print_args) 8await page.evaluate("console.log('hello', 5, { foo: 'bar' })") 9
1def print_args(msg): 2 for arg in msg.args: 3 print(arg.json_value()) 4 5page.on("console", print_args) 6page.evaluate("console.log('hello', 5, { foo: 'bar' })") 7
1page.Console += async (_, msg) => 2{ 3 foreach (var arg in msg.Args) 4 Console.WriteLine(await arg.JsonValueAsync<object>()); 5}; 6 7await page.EvaluateAsync("console.log('hello', 5, { foo: 'bar' })"); 8

event: Page.crash

  • since: v1.8
  • argument: <[Page]>

Emitted when the page crashes. Browser pages might crash if they try to allocate too much memory. When the page crashes, ongoing and subsequent operations will throw.

The most common way to deal with crashes is to catch an exception:

1try { 2 // Crash might happen during a click. 3 await page.click('button'); 4 // Or while waiting for an event. 5 await page.waitForEvent('popup'); 6} catch (e) { 7 // When the page crashes, exception message contains 'crash'. 8} 9
1try { 2 // Crash might happen during a click. 3 page.click("button"); 4 // Or while waiting for an event. 5 page.waitForPopup(() -> {}); 6} catch (PlaywrightException e) { 7 // When the page crashes, exception message contains "crash". 8} 9
1try: 2 # crash might happen during a click. 3 await page.click("button") 4 # or while waiting for an event. 5 await page.wait_for_event("popup") 6except Error as e: 7 pass 8 # when the page crashes, exception message contains "crash". 9
1try: 2 # crash might happen during a click. 3 page.click("button") 4 # or while waiting for an event. 5 page.wait_for_event("popup") 6except Error as e: 7 pass 8 # when the page crashes, exception message contains "crash". 9
1try { 2 // Crash might happen during a click. 3 await page.ClickAsync("button"); 4 // Or while waiting for an event. 5 await page.WaitForPopup(); 6} catch (PlaywrightException e) { 7 // When the page crashes, exception message contains "crash". 8} 9

event: Page.dialog

  • since: v1.8
  • argument: <[Dialog]>

Emitted when a JavaScript dialog appears, such as alert, prompt, confirm or beforeunload. Listener must either [method: Dialog.accept] or [method: Dialog.dismiss] the dialog - otherwise the page will freeze waiting for the dialog, and actions like click will never finish.

Usage

1page.on('dialog', dialog => { 2 dialog.accept(); 3}); 4
1page.onDialog(dialog -> { 2 dialog.accept(); 3}); 4
1page.on("dialog", lambda dialog: dialog.accept()) 2
1page.RequestFailed += (_, request) => 2{ 3 Console.WriteLine(request.Url + " " + request.Failure); 4}; 5

:::note When no [event: Page.dialog] or [event: BrowserContext.dialog] listeners are present, all dialogs are automatically dismissed. :::

event: Page.DOMContentLoaded

  • since: v1.9
  • argument: <[Page]>

Emitted when the JavaScript DOMContentLoaded event is dispatched.

event: Page.download

  • since: v1.8
  • argument: <[Download]>

Emitted when attachment download started. User can access basic file operations on downloaded content via the passed [Download] instance.

event: Page.fileChooser

  • since: v1.9
  • argument: <[FileChooser]>

Emitted when a file chooser is supposed to appear, such as after clicking the <input type=file>. Playwright can respond to it via setting the input files using [method: FileChooser.setFiles] that can be uploaded after that.

1page.on('filechooser', async fileChooser => { 2 await fileChooser.setFiles(path.join(__dirname, '/tmp/myfile.pdf')); 3}); 4
1page.onFileChooser(fileChooser -> { 2 fileChooser.setFiles(Paths.get("/tmp/myfile.pdf")); 3}); 4
1page.on("filechooser", lambda file_chooser: file_chooser.set_files("/tmp/myfile.pdf")) 2
1page.FileChooser += (_, fileChooser) => 2{ 3 fileChooser.SetFilesAsync(@"C:\temp\myfile.pdf"); 4}; 5

event: Page.frameAttached

  • since: v1.9
  • argument: <[Frame]>

Emitted when a frame is attached.

event: Page.frameDetached

  • since: v1.9
  • argument: <[Frame]>

Emitted when a frame is detached.

event: Page.frameNavigated

  • since: v1.9
  • argument: <[Frame]>

Emitted when a frame is navigated to a new url.

event: Page.load

  • since: v1.8
  • argument: <[Page]>

Emitted when the JavaScript load event is dispatched.

event: Page.pageError

  • since: v1.9
  • argument: <[Error]>

Emitted when an uncaught exception happens within the page.

1// Log all uncaught errors to the terminal 2page.on('pageerror', exception => { 3 console.log(`Uncaught exception: "${exception}"`); 4}); 5 6// Navigate to a page with an exception. 7await page.goto('data:text/html,<script>throw new Error("Test")</script>'); 8
1// Log all uncaught errors to the terminal 2page.onPageError(exception -> { 3 System.out.println("Uncaught exception: " + exception); 4}); 5 6// Navigate to a page with an exception. 7page.navigate("data:text/html,<script>throw new Error('Test')</script>"); 8
1# Log all uncaught errors to the terminal 2page.on("pageerror", lambda exc: print(f"uncaught exception: {exc}")) 3 4# Navigate to a page with an exception. 5await page.goto("data:text/html,<script>throw new Error('test')</script>") 6
1# Log all uncaught errors to the terminal 2page.on("pageerror", lambda exc: print(f"uncaught exception: {exc}")) 3 4# Navigate to a page with an exception. 5page.goto("data:text/html,<script>throw new Error('test')</script>") 6
1// Log all uncaught errors to the terminal 2page.PageError += (_, exception) => 3{ 4 Console.WriteLine("Uncaught exception: " + exception); 5}; 6

event: Page.pageError

  • since: v1.9
  • langs: csharp, java
  • argument: <[string]>

event: Page.popup

  • since: v1.8
  • argument: <[Page]>

Emitted when the page opens a new tab or window. This event is emitted in addition to the [event: BrowserContext.page], but only for popups relevant to this page.

The earliest moment that page is available is when it has navigated to the initial url. For example, when opening a popup with window.open('http://example.com'), this event will fire when the network request to "http://example.com" is done and its response has started loading in the popup.

1// Start waiting for popup before clicking. Note no await. 2const popupPromise = page.waitForEvent('popup'); 3await page.getByText('open the popup').click(); 4const popup = await popupPromise; 5console.log(await popup.evaluate('location.href')); 6
1Page popup = page.waitForPopup(() -> { 2 page.getByText("open the popup").click(); 3}); 4System.out.println(popup.evaluate("location.href")); 5
1async with page.expect_event("popup") as page_info: 2 await page.get_by_text("open the popup").click() 3popup = await page_info.value 4print(await popup.evaluate("location.href")) 5
1with page.expect_event("popup") as page_info: 2 page.get_by_text("open the popup").click() 3popup = page_info.value 4print(popup.evaluate("location.href")) 5
1var popup = await page.RunAndWaitForPopupAsync(async () => 2{ 3 await page.GetByText("open the popup").ClickAsync(); 4}); 5Console.WriteLine(await popup.EvaluateAsync<string>("location.href")); 6

:::note Use [method: Page.waitForLoadState] to wait until the page gets to a particular state (you should not need it in most cases). :::

event: Page.request

  • since: v1.8
  • argument: <[Request]>

Emitted when a page issues a request. The [request] object is read-only. In order to intercept and mutate requests, see [method: Page.route] or [method: BrowserContext.route].

event: Page.requestFailed

  • since: v1.9
  • argument: <[Request]>

Emitted when a request fails, for example by timing out.

1page.on('requestfailed', request => { 2 console.log(request.url() + ' ' + request.failure().errorText); 3}); 4
1page.onRequestFailed(request -> { 2 System.out.println(request.url() + " " + request.failure()); 3}); 4
1page.on("requestfailed", lambda request: print(request.url + " " + request.failure.error_text)) 2

:::note HTTP Error responses, such as 404 or 503, are still successful responses from HTTP standpoint, so request will complete with [event: Page.requestFinished] event and not with [event: Page.requestFailed]. A request will only be considered failed when the client cannot get an HTTP response from the server, e.g. due to network error net::ERR_FAILED. :::

event: Page.requestFinished

  • since: v1.9
  • argument: <[Request]>

Emitted when a request finishes successfully after downloading the response body. For a successful response, the sequence of events is request, response and requestfinished.

event: Page.response

  • since: v1.8
  • argument: <[Response]>

Emitted when [response] status and headers are received for a request. For a successful response, the sequence of events is request, response and requestfinished.

event: Page.webSocket

  • since: v1.9
  • argument: <[WebSocket]>

Emitted when [WebSocket] request is sent.

event: Page.worker

  • since: v1.8
  • argument: <[Worker]>

Emitted when a dedicated WebWorker is spawned by the page.

property: Page.accessibility

  • since: v1.8
  • langs: csharp, js, python
  • deprecated: This property is discouraged. Please use other libraries such as Axe if you need to test page accessibility. See our Node.js guide for integration with Axe.
  • type: <[Accessibility]>

async method: Page.addInitScript

  • since: v1.8

Adds a script which would be evaluated in one of the following scenarios:

  • Whenever the page is navigated.
  • Whenever the child frame is attached or navigated. In this case, the script is evaluated in the context of the newly attached frame.

The script is evaluated after the document was created but before any of its scripts were run. This is useful to amend the JavaScript environment, e.g. to seed Math.random.

Usage

An example of overriding Math.random before the page loads:

1// preload.js 2Math.random = () => 42; 3
1// In your playwright script, assuming the preload.js file is in same directory 2await page.addInitScript({ path: './preload.js' }); 3
1await page.addInitScript(mock => { 2 window.mock = mock; 3}, mock); 4
1// In your playwright script, assuming the preload.js file is in same directory 2page.addInitScript(Paths.get("./preload.js")); 3
1# in your playwright script, assuming the preload.js file is in same directory 2await page.add_init_script(path="./preload.js") 3
1# in your playwright script, assuming the preload.js file is in same directory 2page.add_init_script(path="./preload.js") 3
1await page.AddInitScriptAsync(scriptPath: "./preload.js"); 2

:::note The order of evaluation of multiple scripts installed via [method: BrowserContext.addInitScript] and [method: Page.addInitScript] is not defined. :::

async method: Page.check

  • since: v1.8
  • discouraged: Use locator-based [method: Locator.check] instead. Read more about locators.

This method checks an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Ensure that matched element is a checkbox or a radio input. If not, this method throws. If the element is already checked, this method returns immediately.
  3. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  4. Scroll the element into view if needed.
  5. Use [property: Page.mouse] to click in the center of the element.
  6. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set.
  7. Ensure that the element is now checked. If not, this method throws.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

  • since: v1.8

If [option: runBeforeUnload] is false, does not run any unload handlers and waits for the page to be closed. If [option: runBeforeUnload] is true the method will run unload handlers, but will not wait for the page to close.

By default, page.close() does not run beforeunload handlers.

:::note if [option: runBeforeUnload] is passed as true, a beforeunload dialog might be summoned and should be handled manually via [event: Page.dialog] event. :::

option: Page.close.runBeforeUnload

  • since: v1.8
  • runBeforeUnload <[boolean]>

Defaults to false. Whether to run the before unload page handlers.

async method: Page.content

  • since: v1.8
  • returns: <[string]>

Gets the full HTML contents of the page, including the doctype.

method: Page.context

Browser-specific Coverage implementation. See Coverage for more details.

async method: Page.dblclick

  • since: v1.8
  • discouraged: Use locator-based [method: Locator.dblclick] instead. Read more about locators.
  • langs:
    • alias-csharp: DblClickAsync

This method double clicks an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  3. Scroll the element into view if needed.
  4. Use [property: Page.mouse] to double click in the center of the element, or the specified [option: position].
  5. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set. Note that if the first click of the dblclick() triggers a navigation event, this method will throw.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

async method: Page.dispatchEvent

  • since: v1.8
  • discouraged: Use locator-based [method: Locator.dispatchEvent] instead. Read more about locators.

The snippet below dispatches the click event on the element. Regardless of the visibility state of the element, click is dispatched. This is equivalent to calling element.click().

Usage

1await page.dispatchEvent('button#submit', 'click'); 2
1page.dispatchEvent("button#submit", "click"); 2
1await page.dispatch_event("button#submit", "click") 2
1page.dispatch_event("button#submit", "click") 2
1await page.DispatchEventAsync("button#submit", "click"); 2

Under the hood, it creates an instance of an event based on the given [param: type], initializes it with [param: eventInit] properties and dispatches it on the element. Events are composed, cancelable and bubble by default.

Since [param: eventInit] is event-specific, please refer to the events documentation for the lists of initial properties:

You can also specify JSHandle as the property value if you want live objects to be passed into the event:

1// Note you can only create DataTransfer in Chromium and Firefox 2const dataTransfer = await page.evaluateHandle(() => new DataTransfer()); 3await page.dispatchEvent('#source', 'dragstart', { dataTransfer }); 4

async method: Page.evalOnSelector

  • since: v1.9
  • discouraged: This method does not wait for the element to pass actionability checks and therefore can lead to the flaky tests. Use [method: Locator.evaluate], other [Locator] helper methods or web-first assertions instead.
  • langs:
    • alias-python: eval_on_selector
    • alias-js: $eval
  • returns: <[Serializable]>

The method finds an element matching the specified selector within the page and passes it as a first argument to [param: expression]. If no elements match the selector, the method throws an error. Returns the value of [param: expression].

If [param: expression] returns a [Promise], then [method: Page.evalOnSelector] would wait for the promise to resolve and return its value.

Usage

1const searchValue = await page.$eval('#search', el => el.value); 2const preloadHref = await page.$eval('link[rel=preload]', el => el.href); 3const html = await page.$eval('.main-container', (e, suffix) => e.outerHTML + suffix, 'hello'); 4// In TypeScript, this example requires an explicit type annotation (HTMLLinkElement) on el: 5const preloadHrefTS = await page.$eval('link[rel=preload]', (el: HTMLLinkElement) => el.href); 6

The method finds all elements matching the specified selector within the page and passes an array of matched elements as a first argument to [param: expression]. Returns the result of [param: expression] invocation.

If [param: expression] returns a [Promise], then [method: Page.evalOnSelectorAll] would wait for the promise to resolve and return its value.

Usage

1const divCounts = await page.$$eval('div', (divs, min) => divs.length >= min, 10); 2

  • returns: <[Serializable]>

Returns the value of the [param: expression] invocation.

If the function passed to the [method: Page.evaluate] returns a [Promise], then [method: Page.evaluate] would wait for the promise to resolve and return its value.

If the function passed to the [method: Page.evaluate] returns a non-[Serializable] value, then [method: Page.evaluate] resolves to undefined. Playwright also supports transferring some additional values that are not serializable by JSON: -0, NaN, Infinity, -Infinity.

Usage

Passing argument to [param: expression]:

1const result = await page.evaluate(([x, y]) => { 2 return Promise.resolve(x * y); 3}, [7, 8]); 4console.log(result); // prints "56" 5
1Object result = page.evaluate("([x, y]) => {\n" + 2 " return Promise.resolve(x * y);\n" + 3 "}", Arrays.asList(7, 8)); 4System.out.println(result); // prints "56" 5

1var result = await page.EvaluateAsync<int>("([x, y]) => Promise.resolve(x * y)", new[] { 7, 8 }); 2Console.WriteLine(result); 3

A string can also be passed in instead of a function:

1console.log(await page.evaluate('1 + 2')); // prints "3" 2const x = 10; 3console.log(await page.evaluate(`1 + ${x}`)); // prints "11" 4
1System.out.println(page.evaluate("1 + 2")); // prints "3" 2

Returns the value of the [param: expression] invocation as a [JSHandle].

The only difference between [method: Page.evaluate] and [method: Page.evaluateHandle] is that [method: Page.evaluateHandle] returns [JSHandle].

If the function passed to the [method: Page.evaluateHandle] returns a [Promise], then [method: Page.evaluateHandle] would wait for the promise to resolve and return its value.

async method: Page.exposeBinding

  • since: v1.8

The method adds a function called [param: name] on the window object of every frame in this page. When called, the function executes [param: callback] and returns a [Promise] which resolves to the return value of [param: callback]. If the [param: callback] returns a [Promise], it will be awaited.

The first argument of the [param: callback] function contains information about the caller: { browserContext: BrowserContext, page: Page, frame: Frame }.

See [method: BrowserContext.exposeBinding] for the context-wide version.

:::note Functions installed via [method: Page.exposeBinding] survive navigations. :::

  • since: v1.8
  • name <[string]>

Name of the function on the window object.

param: Page.exposeBinding.callback

  • since: v1.8
  • callback <[function]>

Callback function that will be called in the Playwright's context.

option: Page.exposeBinding.handle

  • since: v1.8
  • handle <[boolean]>

Whether to pass the argument as a handle, instead of passing by value. When passing a handle, only one argument is supported. When passing by value, multiple arguments are supported.

async method: Page.exposeFunction

  • since: v1.8

The method adds a function called [param: name] on the window object of every frame in the page. When called, the function executes [param: callback] and returns a [Promise] which resolves to the return value of [param: callback].

If the [param: callback] returns a [Promise], it will be awaited.

See [method: BrowserContext.exposeFunction] for context-wide exposed function.

:::note Functions installed via [method: Page.exposeFunction] survive navigations. :::

Returns the main resource response. In case of multiple redirects, the navigation will resolve with the first non-redirect response.

The method will throw an error if:

  • there's an SSL error (e.g. in case of self-signed certificates).
  • target URL is invalid.
  • the [option: timeout] is exceeded during navigation.
  • the remote server does not respond or is unreachable.
  • the main resource failed to load.

The method will not throw an error when any valid HTTP status code is returned by the remote server, including 404 "Not Found" and 500 "Internal Server Error". The status code for such responses can be retrieved by calling [method: Response.status].

:::note The method either throws an error or returns a main resource response. The only exceptions are navigation to about:blank or navigation to the same URL with a different hash, which would succeed and return null. :::

:::note Headless mode doesn't support navigation to a PDF document. See the upstream issue. :::

async method: Page.hover

  • since: v1.8
  • discouraged: Use locator-based [method: Locator.hover] instead. Read more about locators.

This method hovers over an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  3. Scroll the element into view if needed.
  4. Use [property: Page.mouse] to hover over the center of the element, or the specified [option: position].
  5. Wait for initiated navigations to either succeed or fail, unless noWaitAfter option is set.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

  • since: v1.10
  • langs: java

Adds one-off [Dialog] handler. The handler will be removed immediately after next [Dialog] is created.

1page.onceDialog(dialog -> { 2 dialog.accept("foo"); 3}); 4 5// prints 'foo' 6System.out.println(page.evaluate("prompt('Enter string:')")); 7 8// prints 'null' as the dialog will be auto-dismissed because there are no handlers. 9System.out.println(page.evaluate("prompt('Enter string:')")); 10

This code above is equivalent to:

1Consumer<Dialog> handler = new Consumer<Dialog>() { 2 @Override 3 public void accept(Dialog dialog) { 4 dialog.accept("foo"); 5 page.offDialog(this); 6 } 7}; 8page.onDialog(handler); 9 10// prints 'foo' 11System.out.println(page.evaluate("prompt('Enter string:')")); 12 13// prints 'null' as the dialog will be auto-dismissed because there are no handlers. 14System.out.println(page.evaluate("prompt('Enter string:')")); 15

param: Page.onceDialog.handler

  • since: v1.10
  • handler <[function]([Dialog])>

Receives the [Dialog] object, it must either [method: Dialog.accept] or [method: Dialog.dismiss] the dialog - otherwise the page will freeze waiting for the dialog, and actions like click will never finish.

async method: Page.opener

  • since: v1.8
  • returns: <[null]|[Page]>

Returns the opener for popup pages and null for others. If the opener has been closed already the returns null.

async method: Page.pause

  • since: v1.9

Pauses script execution. Playwright will stop executing the script and wait for the user to either press 'Resume' button in the page overlay or to call playwright.resume() in the DevTools console.

User can inspect selectors or perform manual steps while paused. Resume will continue running the original script from the place it was paused.

:::note This method requires Playwright to be started in a headed mode, with a falsy [option: headless] value in the [method: BrowserType.launch]. :::

async method: Page.pdf

  • since: v1.8
  • returns: <[Buffer]>

Returns the PDF buffer.

:::note Generating a pdf is currently only supported in Chromium headless. :::

page.pdf() generates a pdf of the page with print css media. To generate a pdf with screen media, call [method: Page.emulateMedia] before calling page.pdf():

:::note By default, page.pdf() generates a pdf with modified colors for printing. Use the -webkit-print-color-adjust property to force rendering of exact colors. :::

Usage

1// Generates a PDF with 'screen' media type. 2await page.emulateMedia({ media: 'screen' }); 3await page.pdf({ path: 'page.pdf' }); 4
1// Generates a PDF with "screen" media type. 2page.emulateMedia(new Page.EmulateMediaOptions().setMedia(Media.SCREEN)); 3page.pdf(new Page.PdfOptions().setPath(Paths.get("page.pdf"))); 4

async method: Page.press

  • since: v1.8
  • discouraged: Use locator-based [method: Locator.press] instead. Read more about locators.

Focuses the element, and then uses [method: Keyboard.down] and [method: Keyboard.up].

[param: key] can specify the intended keyboardEvent.key value or a single character to generate the text for. A superset of the [param: key] values can be found here. Examples of the keys are:

F1 - F12, Digit0- Digit9, KeyA- KeyZ, Backquote, Minus, Equal, Backslash, Backspace, Tab, Delete, Escape, ArrowDown, End, Enter, Home, Insert, PageDown, PageUp, ArrowRight, ArrowUp, etc.

Following modification shortcuts are also supported: Shift, Control, Alt, Meta, ShiftLeft.

Holding down Shift will type the text that corresponds to the [param: key] in the upper case.

If [param: key] is a single character, it is case-sensitive, so the values a and A will generate different respective texts.

Shortcuts such as key: "Control+o" or key: "Control+Shift+T" are supported as well. When specified with the modifier, modifier is pressed and being held while the subsequent key is being pressed.

Usage

1const page = await browser.newPage(); 2await page.goto('https://keycode.info'); 3await page.press('body', 'A'); 4await page.screenshot({ path: 'A.png' }); 5await page.press('body', 'ArrowLeft'); 6await page.screenshot({ path: 'ArrowLeft.png' }); 7await page.press('body', 'Shift+O'); 8await page.screenshot({ path: 'O.png' }); 9await browser.close(); 10

  • type: <[APIRequestContext]>

API testing helper associated with this page. This method returns the same instance as [property: BrowserContext.request] on the page's context. See [property: BrowserContext.request] for more details.

async method: Page.route

  • since: v1.8

Routing provides the capability to modify network requests that are made by a page.

Once routing is enabled, every request matching the url pattern will stall unless it's continued, fulfilled or aborted.

:::note The handler will only be called for the first url if the response is a redirect. :::

:::note [method: Page.route] will not intercept requests intercepted by Service Worker. See this issue. We recommend disabling Service Workers when using request interception by setting [option: Browser.newContext.serviceWorkers] to 'block'. :::

Usage

An example of a naive handler that aborts all image requests:

1const page = await browser.newPage(); 2await page.route('**/*.{png,jpg,jpeg}', route => route.abort()); 3await page.goto('https://example.com'); 4await browser.close(); 5
1Page page = browser.newPage(); 2page.route("**/*.{png,jpg,jpeg}", route -> route.abort()); 3page.navigate("https://example.com"); 4browser.close(); 5
1page = await browser.new_page() 2await page.route("**/*.{png,jpg,jpeg}", lambda route: route.abort()) 3await page.goto("https://example.com") 4await browser.close() 5
1page = browser.new_page() 2page.route("**/*.{png,jpg,jpeg}", lambda route: route.abort()) 3page.goto("https://example.com") 4browser.close() 5
1var page = await browser.NewPageAsync(); 2await page.RouteAsync("**/*.{png,jpg,jpeg}", async r => await r.AbortAsync()); 3await page.GotoAsync("https://www.microsoft.com"); 4

or the same snippet using a regex pattern instead:

1const page = await browser.newPage(); 2await page.route(/(\.png$)|(\.jpg$)/, route => route.abort()); 3await page.goto('https://example.com'); 4await browser.close(); 5
1Page page = browser.newPage(); 2page.route(Pattern.compile("(\\.png$)|(\\.jpg$)"),route -> route.abort()); 3page.navigate("https://example.com"); 4browser.close(); 5
1page = await browser.new_page() 2await page.route(re.compile(r"(\.png$)|(\.jpg$)"), lambda route: route.abort()) 3await page.goto("https://example.com") 4await browser.close() 5
1page = browser.new_page() 2page.route(re.compile(r"(\.png$)|(\.jpg$)"), lambda route: route.abort()) 3page.goto("https://example.com") 4browser.close() 5
1var page = await browser.NewPageAsync(); 2await page.RouteAsync(new Regex("(\\.png$)|(\\.jpg$)"), async r => await r.AbortAsync()); 3await page.GotoAsync("https://www.microsoft.com"); 4

It is possible to examine the request to decide the route action. For example, mocking all requests that contain some post data, and leaving all other requests as is:

1await page.route('/api/**', route => { 2 if (route.request().postData().includes('my-string')) 3 route.fulfill({ body: 'mocked-data' }); 4 else 5 route.continue(); 6}); 7
1page.route("/api/**", route -> { 2 if (route.request().postData().contains("my-string")) 3 route.fulfill(new Route.FulfillOptions().setBody("mocked-data")); 4 else 5 route.resume(); 6}); 7
1def handle_route(route): 2 if ("my-string" in route.request.post_data): 3 route.fulfill(body="mocked-data") 4 else: 5 route.continue_() 6await page.route("/api/**", handle_route) 7
1def handle_route(route): 2 if ("my-string" in route.request.post_data): 3 route.fulfill(body="mocked-data") 4 else: 5 route.continue_() 6page.route("/api/**", handle_route) 7
1await page.RouteAsync("/api/**", async r => 2{ 3 if (r.Request.PostData.Contains("my-string")) 4 await r.FulfillAsync(new() { Body = "mocked-data" }); 5 else 6 await r.ContinueAsync(); 7}); 8

Page routes take precedence over browser context routes (set up with [method: BrowserContext.route]) when request matches both handlers.

To remove a route with its handler you can use [method: Page.unroute].

  • since: v1.8
  • discouraged: Use locator-based [method: Locator.selectOption] instead. Read more about locators.
  • returns: <[Array]<[string]>>

This method waits for an element matching [param: selector], waits for actionability checks, waits until all specified options are present in the <select> element and selects these options.

If the target element is not a <select> element, this method throws an error. However, if the element is inside the <label> element that has an associated control, the control will be used instead.

Returns the array of option values that have been successfully selected.

Triggers a change and input event once all the provided options have been selected.

async method: Page.setChecked

  • since: v1.15
  • discouraged: Use locator-based [method: Locator.setChecked] instead. Read more about locators.

This method checks or unchecks an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Ensure that matched element is a checkbox or a radio input. If not, this method throws.
  3. If the element already has the right checked state, this method returns immediately.
  4. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  5. Scroll the element into view if needed.
  6. Use [property: Page.mouse] to click in the center of the element.
  7. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set.
  8. Ensure that the element is now checked or unchecked. If not, this method throws.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

async method: Page.setInputFiles

  • since: v1.8
  • discouraged: Use locator-based [method: Locator.setInputFiles] instead. Read more about locators.

Sets the value of the file input to these file paths or files. If some of the filePaths are relative paths, then they are resolved relative to the current working directory. For empty array, clears the selected files.

This method expects [param: selector] to point to an input element. However, if the element is inside the <label> element that has an associated control, targets the control instead.

param: Page.setInputFiles.selector = %%-input-selector-%%

  • since: v1.8

async method: Page.setViewportSize

  • since: v1.8

In the case of multiple pages in a single browser, each page can have its own viewport size. However, [method: Browser.newContext] allows to set viewport size (and more) for all pages in the context at once.

[method: Page.setViewportSize] will resize the page. A lot of websites don't expect phones to change size, so you should set the viewport size before navigating to the page. [method: Page.setViewportSize] will also reset screen size, use [method: Browser.newContext] with screen and viewport parameters if you need better control of these properties.

Usage

1const page = await browser.newPage(); 2await page.setViewportSize({ 3 width: 640, 4 height: 480, 5}); 6await page.goto('https://example.com'); 7
1Page page = browser.newPage(); 2page.setViewportSize(640, 480); 3page.navigate("https://example.com"); 4
1page = await browser.new_page() 2await page.set_viewport_size({"width": 640, "height": 480}) 3await page.goto("https://example.com") 4
1page = browser.new_page() 2page.set_viewport_size({"width": 640, "height": 480}) 3page.goto("https://example.com") 4
1var page = await browser.NewPageAsync(); 2await page.SetViewportSizeAsync(640, 480); 3await page.GotoAsync("https://www.microsoft.com"); 4

async method: Page.tap

  • since: v1.8
  • discouraged: Use locator-based [method: Locator.tap] instead. Read more about locators.

This method taps an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  3. Scroll the element into view if needed.
  4. Use [property: Page.touchscreen] to tap the center of the element, or the specified [option: position].
  5. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

:::note [method: Page.tap] the method will throw if [option: hasTouch] option of the browser context is false. :::

async method: Page.type

  • since: v1.8
  • deprecated: In most cases, you should use [method: Locator.fill] instead. You only need to press keys one by one if there is special keyboard handling on the page - in this case use [method: Locator.pressSequentially].

Sends a keydown, keypress/input, and keyup event for each character in the text. page.type can be used to send fine-grained keyboard events. To fill values in form fields, use [method: Page.fill].

To press a special key, like Control or ArrowDown, use [method: Keyboard.press].

async method: Page.uncheck

  • since: v1.8
  • discouraged: Use locator-based [method: Locator.uncheck] instead. Read more about locators.

This method unchecks an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Ensure that matched element is a checkbox or a radio input. If not, this method throws. If the element is already unchecked, this method returns immediately.
  3. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  4. Scroll the element into view if needed.
  5. Use [property: Page.mouse] to click in the center of the element.
  6. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set.
  7. Ensure that the element is now unchecked. If not, this method throws.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.
