Page provides methods to interact with a single tab or [extension background page](https://developer.chrome.com/extensions/background_pages) in Chromium.
:::note
One Browser instance might have multiple Page instances.
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Page` class.
## Example 1
This example creates a page, navigates it to a URL, and then saves a screenshot:
```ts
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://example.com');
await page.screenshot({path: 'screenshot.png'});
await browser.close();
})();
```
The Page class extends from Puppeteer's [EventEmitter](./puppeteer.eventemitter.md) class and will emit various events which are documented in the [PageEmittedEvents](./puppeteer.pageemittedevents.md) enum.
## Example 2
This example logs a message for a single page `load` event:
| [$(selector)](./puppeteer.page._.md) | | Runs <code>document.querySelector</code> within the page. If no element matches the selector, the return value resolves to <code>null</code>. |
| [$$(selector)](./puppeteer.page.__.md) | | The method runs <code>document.querySelectorAll</code> within the page. If no elements match the selector, the return value resolves to <code>[]</code>. |
| [$$eval(selector, pageFunction, args)](./puppeteer.page.__eval.md) | | This method runs <code>Array.from(document.querySelectorAll(selector))</code> within the page and passes the result as the first argument to the <code>pageFunction</code>. |
| [$eval(selector, pageFunction, args)](./puppeteer.page._eval.md) | | This method runs <code>document.querySelector</code> within the page and passes the result as the first argument to the <code>pageFunction</code>. |
| [$x(expression)](./puppeteer.page._x.md) | | The method evaluates the XPath expression relative to the page document as its context node. If there are no such elements, the method resolves to an empty array. |
| [addScriptTag(options)](./puppeteer.page.addscripttag.md) | | Adds a <code><script></code> tag into the page with the desired URL or content. |
| [addStyleTag(options)](./puppeteer.page.addstyletag.md) | | Adds a <code><link rel="stylesheet"></code> tag into the page with the desired URL or a <code><style type="text/css"></code> tag with the content. |
| [authenticate(credentials)](./puppeteer.page.authenticate.md) | | Provide credentials for <code>HTTP authentication</code>. |
| [bringToFront()](./puppeteer.page.bringtofront.md) | | Brings page to front (activates tab). |
| [browser()](./puppeteer.page.browser.md) | | Get the browser the page belongs to. |
| [browserContext()](./puppeteer.page.browsercontext.md) | | Get the browser context that the page belongs to. |
| [click(selector, options)](./puppeteer.page.click.md) | | This method fetches an element with <code>selector</code>, scrolls it into view if needed, and then uses [Page.mouse](./puppeteer.page.mouse.md) to click in the center of the element. If there's no element matching <code>selector</code>, the method throws an error. |
| [cookies(urls)](./puppeteer.page.cookies.md) | | If no URLs are specified, this method returns cookies for the current page URL. If URLs are specified, only cookies for those URLs are returned. |
| [createPDFStream(options)](./puppeteer.page.createpdfstream.md) | | Generates a PDF of the page with the <code>print</code> CSS media type. |
| [evaluateOnNewDocument(pageFunction, args)](./puppeteer.page.evaluateonnewdocument.md) | | <p>Adds a function which would be invoked in one of the following scenarios:</p><p>- whenever the page is navigated</p><p>- whenever the child frame is attached or navigated. In this case, the function is invoked in the context of the newly attached frame.</p><p>The function is invoked 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 <code>Math.random</code>.</p> |
| [exposeFunction(name, pptrFunction)](./puppeteer.page.exposefunction.md) | | <p>The method adds a function called <code>name</code> on the page's <code>window</code> object. When called, the function executes <code>puppeteerFunction</code> in node.js and returns a <code>Promise</code> which resolves to the return value of <code>puppeteerFunction</code>.</p><p>If the puppeteerFunction returns a <code>Promise</code>, it will be awaited.</p><p>NOTE: Functions installed via <code>page.exposeFunction</code> survive navigations.</p> |
| [focus(selector)](./puppeteer.page.focus.md) | | This method fetches an element with <code>selector</code> and focuses it. If there's no element matching <code>selector</code>, the method throws an error. |
| [frames()](./puppeteer.page.frames.md) | | |
| [goBack(options)](./puppeteer.page.goback.md) | | This method navigate to the previous page in history. |
| [goForward(options)](./puppeteer.page.goforward.md) | | This method navigate to the next page in history. |
| [hover(selector)](./puppeteer.page.hover.md) | | This method fetches an element with <code>selector</code>, scrolls it into view if needed, and then uses [Page.mouse](./puppeteer.page.mouse.md) to hover over the center of the element. If there's no element matching <code>selector</code>, the method throws an error. |
| [isClosed()](./puppeteer.page.isclosed.md) | | Indicates that the page has been closed. |
| [on(eventName, handler)](./puppeteer.page.on.md) | | <p>Listen to page events.</p><p>:::note</p><p>This method exists to define event typings and handle proper wireup of cooperative request interception. Actual event listening and dispatching is delegated to [EventEmitter](./puppeteer.eventemitter.md).</p><p>:::</p> |
| [queryObjects(prototypeHandle)](./puppeteer.page.queryobjects.md) | | This method iterates the JavaScript heap and finds all objects with the given prototype. |
| [select(selector, values)](./puppeteer.page.select.md) | | Triggers a <code>change</code> and <code>input</code> event once all the provided options have been selected. If there's no <code><select></code> element matching <code>selector</code>, the method throws an error. |
| [setCacheEnabled(enabled)](./puppeteer.page.setcacheenabled.md) | | Toggles ignoring cache for each request based on the enabled state. By default, caching is enabled. |
| [setDefaultNavigationTimeout(timeout)](./puppeteer.page.setdefaultnavigationtimeout.md) | | <p>This setting will change the default maximum navigation time for the following methods and related shortcuts:</p><p>- [page.goBack(options)](./puppeteer.page.goback.md)</p><p>- [page.goForward(options)](./puppeteer.page.goforward.md)</p><p>- [page.goto(url,options)](./puppeteer.page.goto.md)</p><p>- [page.reload(options)](./puppeteer.page.reload.md)</p><p>- [page.setContent(html,options)](./puppeteer.page.setcontent.md)</p><p>- [page.waitForNavigation(options)](./puppeteer.page.waitfornavigation.md)</p> |
| [setExtraHTTPHeaders(headers)](./puppeteer.page.setextrahttpheaders.md) | | The extra HTTP headers will be sent with every request the page initiates. NOTE: All HTTP header names are lowercased. (HTTP headers are case-insensitive, so this shouldn’t impact your server code.) NOTE: page.setExtraHTTPHeaders does not guarantee the order of headers in the outgoing requests. |
| [setGeolocation(options)](./puppeteer.page.setgeolocation.md) | | Sets the page's geolocation. |
| [setRequestInterception(value)](./puppeteer.page.setrequestinterception.md) | | <p>Activating request interception enables [HTTPRequest.abort()](./puppeteer.httprequest.abort.md), [HTTPRequest.continue()](./puppeteer.httprequest.continue.md) and [HTTPRequest.respond()](./puppeteer.httprequest.respond.md) methods. This provides the capability to modify network requests that are made by a page.</p><p>Once request interception is enabled, every request will stall unless it's continued, responded or aborted; or completed using the browser cache.</p><p>NOTE: Enabling request interception disables page caching.</p><p>See the [Request interception guide](https://pptr.dev/next/guides/request-interception) for more details.</p> |
| [setViewport(viewport)](./puppeteer.page.setviewport.md) | | <p><code>page.setViewport</code> will resize the page. A lot of websites don't expect phones to change size, so you should set the viewport before navigating to the page.</p><p>In the case of multiple pages in a single browser, each page can have its own viewport size.</p> |
| [tap(selector)](./puppeteer.page.tap.md) | | This method fetches an element with <code>selector</code>, scrolls it into view if needed, and then uses [Page.touchscreen](./puppeteer.page.touchscreen.md) to tap in the center of the element. If there's no element matching <code>selector</code>, the method throws an error. |
| [target()](./puppeteer.page.target.md) | | |
| [title()](./puppeteer.page.title.md) | | |
| [type(selector, text, options)](./puppeteer.page.type.md) | | <p>Sends a <code>keydown</code>, <code>keypress/input</code>, and <code>keyup</code> event for each character in the text.</p><p>To press a special key, like <code>Control</code> or <code>ArrowDown</code>, use [Keyboard.press()](./puppeteer.keyboard.press.md).</p> |
| [waitForFileChooser(options)](./puppeteer.page.waitforfilechooser.md) | | <p>This method is typically coupled with an action that triggers file choosing.</p><p>:::caution</p><p>This must be called before the file chooser is launched. It will not return a currently active file chooser.</p><p>:::</p> |
| [waitForFunction(pageFunction, options, args)](./puppeteer.page.waitforfunction.md) | | Waits for a function to finish evaluating in the page's context. |
| [waitForNavigation(options)](./puppeteer.page.waitfornavigation.md) | | Waits for the page to navigate to a new URL or to reload. It is useful when you run code that will indirectly cause the page to navigate. |
| [waitForSelector(selector, options)](./puppeteer.page.waitforselector.md) | | <p>Wait for the <code>selector</code> to appear in page. If at the moment of calling the method the <code>selector</code> already exists, the method will return immediately. If the <code>selector</code> doesn't appear after the <code>timeout</code> milliseconds of waiting, the function will throw.</p><p>This method works across navigations:</p> |
.then(() => console.log('First URL with image: ' + currentURL));
for (currentURL of [
'https://example.com',
'https://google.com',
'https://bbc.com',
]) {
await page.goto(currentURL);
}
await browser.close();
})();
```
|
| [waitForTimeout(milliseconds)](./puppeteer.page.waitfortimeout.md) | | Causes your script to wait for the given number of milliseconds. |
| [waitForXPath(xpath, options)](./puppeteer.page.waitforxpath.md) | | <p>Wait for the <code>xpath</code> to appear in page. If at the moment of calling the method the <code>xpath</code> already exists, the method will return immediately. If the <code>xpath</code> doesn't appear after the <code>timeout</code> milliseconds of waiting, the function will throw.</p><p>This method works across navigation</p>
```ts
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
let currentURL;
page
.waitForXPath('//img')
.then(() => console.log('First URL with image: ' + currentURL));
