# class: Dialog

[Dialog] objects are dispatched by page via the [`event: Page.dialog`] event.

An example of using `Dialog` class:

```js
const { chromium } = require('playwright');  // Or 'firefox' or 'webkit'.

(async () => {
  const browser = await chromium.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'));
})();
```

```python async
import asyncio
from playwright.async_api import async_playwright

async def handle_dialog(dialog):
    print(dialog.message)
    await dialog.dismiss()

async def run(playwright):
    chromium = playwright.chromium
    browser = await chromium.launch()
    page = await browser.new_page()
    page.on("dialog", handle_dialog)
    page.evaluate("alert('1')")
    await browser.close()

async def main():
    async with async_playwright() as playwright:
        await run(playwright)
asyncio.run(main())
```

```python sync
# FIXME
from playwright.sync_api import sync_playwright

def handle_dialog(dialog):
    print(dialog.message)
    await dialog.dismiss()

def run(playwright):
    chromium = playwright.chromium
    browser = chromium.launch()
    page = browser.new_page()
    page.on("dialog", handle_dialog)
    page.evaluate("alert('1')")
    browser.close()

with sync_playwright() as playwright:
    run(playwright)
```
