## Frame.waitFor() method

> Warning: This API is now obsolete.
> 
> Don't use this method directly. Instead use the more explicit methods available: [Frame.waitForSelector()](./puppeteer.frame.waitforselector.md)<!-- -->, [Frame.waitForXPath()](./puppeteer.frame.waitforxpath.md)<!-- -->, [Frame.waitForFunction()](./puppeteer.frame.waitforfunction.md) or [Frame.waitForTimeout()](./puppeteer.frame.waitfortimeout.md)<!-- -->.

<b>Signature:</b>

```typescript
waitFor(selectorOrFunctionOrTimeout: string | number | Function, options?: {}, ...args: SerializableOrJSHandle[]): Promise<JSHandle | null>;
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  selectorOrFunctionOrTimeout | string \| number \| Function | a selector, predicate or timeout to wait for. |
|  options | {} | optional waiting parameters. |
|  args | [SerializableOrJSHandle](./puppeteer.serializableorjshandle.md)<!-- -->\[\] | arguments to pass to <code>pageFunction</code>. |

<b>Returns:</b>

Promise&lt;[JSHandle](./puppeteer.jshandle.md) \| null&gt;

## Remarks

This method behaves differently depending on the first parameter. If it's a `string`<!-- -->, it will be treated as a `selector` or `xpath` (if the string starts with `//`<!-- -->). This method then is a shortcut for [Frame.waitForSelector()](./puppeteer.frame.waitforselector.md) or [Frame.waitForXPath()](./puppeteer.frame.waitforxpath.md)<!-- -->.

If the first argument is a function this method is a shortcut for [Frame.waitForFunction()](./puppeteer.frame.waitforfunction.md)<!-- -->.

If the first argument is a `number`<!-- -->, it's treated as a timeout in milliseconds and the method returns a promise which resolves after the timeout.
