Frame

Frame class

At every point of time, page exposes its current frame tree via the page.mainFrame and frame.childFrames methods.

Signature:

export declare class Frame 

Remarks

Frame object lifecycles are controlled by three events that are all dispatched on the page object:

• PageEmittedEvents.FrameAttached

• PageEmittedEvents.FrameNavigated

• PageEmittedEvents.FrameDetached

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the Frame class.

Example 1

An example of dumping frame tree:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://www.google.com/chrome/browser/canary.html');
  dumpFrameTree(page.mainFrame(), '');
  await browser.close();

  function dumpFrameTree(frame, indent) {
    console.log(indent + frame.url());
    for (const child of frame.childFrames()) {
    dumpFrameTree(child, indent + '  ');
    }
  }
})();

Example 2

An example of getting text from an iframe element:

const frame = page.frames().find(frame => frame.name() === 'myframe');
const text = await frame.$eval('.selector', element => element.textContent);
console.log(text);
