Puppeteer.registerCustomQueryHandler

Puppeteer.registerCustomQueryHandler() method

Signature:

class Puppeteer {
  static registerCustomQueryHandler(
    name: string,
    queryHandler: CustomQueryHandler
  ): void;
}

Parameters

Parameter Type Description
name string The name that the custom query handler will be registered under.
queryHandler CustomQueryHandler The custom query handler to register.

const aHandle = await page.$('text/…');
