# Frame class
|
|
|
|
At every point of time, page exposes its current frame tree via the [page.mainFrame](./puppeteer.page.mainframe.md) and [frame.childFrames](./puppeteer.frame.childframes.md) methods.
|
|
|
|
**Signature:**
|
|
|
|
```typescript
|
|
export declare class Frame
|
|
```
|
|
|
|
## Remarks
|
|
|
|
`Frame` object lifecycles are controlled by three events that are all dispatched on the page object:
|
|
|
|
- [PageEmittedEvents.FrameAttached](./puppeteer.pageemittedevents.md)
|
|
|
|
- [PageEmittedEvents.FrameNavigated](./puppeteer.pageemittedevents.md)
|
|
|
|
- [PageEmittedEvents.FrameDetached](./puppeteer.pageemittedevents.md)
|
|
|
|
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:
|
|
|
|
```ts
|
|
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:
|
|
|
|
```ts
|
|
const frame = page.frames().find(frame => frame.name() === 'myframe');
|
|
const text = await frame.$eval('.selector', element => element.textContent);
|
|
console.log(text);
|
|
```
|
