# Dialog class

Dialog instances are dispatched by the [Page](./puppeteer.page.md) via the `dialog` event.

#### Signature:

```typescript
export declare abstract class Dialog
```

## Remarks

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

## Example

```ts
import puppeteer from 'puppeteer';

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  page.on('dialog', async dialog => {
    console.log(dialog.message());
    await dialog.dismiss();
    await browser.close();
  });
  page.evaluate(() => alert('1'));
})();
```
