Frame.waitFor() method
Warning: This API is now obsolete.
Don't use this method directly. Instead use the more explicit methods available: Frame.waitForSelector(), Frame.waitForXPath(), Frame.waitForFunction() or Frame.waitForTimeout().
Signature:
waitFor(selectorOrFunctionOrTimeout: string | number | Function, options?: Record<string, unknown>, ...args: SerializableOrJSHandle[]): Promise<JSHandle | null>;
Parameters
| Parameter | Type | Description |
|---|---|---|
| selectorOrFunctionOrTimeout | string | number | Function | a selector, predicate or timeout to wait for. |
| options | Record<string, unknown> | optional waiting parameters. |
| args | SerializableOrJSHandle[] | arguments to pass to pageFunction. |
Returns:
Promise<JSHandle | null>
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() or Frame.waitForXPath().
If the first argument is a function this method is a shortcut for Frame.waitForFunction().
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.
