A string can also be passed in instead of a function:
const aHandle = await page.evaluateHandle('document'); // Handle for the 'document'
JSHandle instances can be passed as arguments to the page.evaluateHandle:
const aHandle = await page.evaluateHandle(() => document.body); const resultHandle = await page.evaluateHandle(body => body.innerHTML, aHandle); console.log(await resultHandle.jsonValue()); await resultHandle.dispose();
