# Frame class
Represents a DOM frame.
To understand frames, you can think of frames as `<iframe>` elements. Just like iframes, frames can be nested, and when JavaScript is executed in a frame, the JavaScript does not effect frames inside the ambient frame the JavaScript executes in.
#### Signature:
```typescript
export declare abstract class Frame extends EventEmitter<FrameEvents>
```
**Extends:** [EventEmitter](./puppeteer.eventemitter.md)&lt;[FrameEvents](./puppeteer.frameevents.md)&gt;
## Remarks
Frame lifecycles are controlled by three events that are all dispatched on the parent [page](./puppeteer.frame.page.md):
- [PageEvent.FrameAttached](./puppeteer.pageevent.md) - [PageEvent.FrameNavigated](./puppeteer.pageevent.md) - [PageEvent.FrameDetached](./puppeteer.pageevent.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
At any point in time, [pages](./puppeteer.page.md) expose their current frame tree via the [Page.mainFrame()](./puppeteer.page.mainframe.md) and [Frame.childFrames()](./puppeteer.frame.childframes.md) methods.
## Example 2
An example of dumping frame tree:
```ts
import puppeteer from '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 3
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);
```
