# Page.waitForSelector() method
Wait for the `selector` to appear in page. If at the moment of calling the method the `selector` already exists, the method will return immediately. If the `selector` doesn't appear after the `timeout` milliseconds of waiting, the function will throw.
This method works across navigations:
```ts
import puppeteer from 'puppeteer';
2022-07-05 13:41:43 +00:00
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
let currentURL;
page
.waitForSelector('img')
.then(() => console.log('First URL with image: ' + currentURL));
for (currentURL of [
'https://example.com',
'https://google.com',
'https://bbc.com',
]) {
await page.goto(currentURL);
}
await browser.close();
})();
```
#### Signature:
