If polling is a number, then it is treated as an interval in milliseconds at which the function would be executed. If polling is a string, then it can be one of the following values:- raf - to constantly execute pageFunction in requestAnimationFrame callback. This is the tightest polling mode which is suitable to observe styling changes.- mutation - to execute pageFunction on every DOM mutation. | | [timeout](./puppeteer.framewaitforfunctionoptions.timeout.md) | number | Maximum time to wait in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable the timeout. Puppeteer's default timeout can be changed using [Page.setDefaultTimeout()](./puppeteer.page.setdefaulttimeout.md). |
