问题 I know that I can use copy() function on the console to add content to the clipboard. When I am on any other page copy('test') works. When I am on youtube I get: Uncaught TypeError: copy is not a function How can I fix this. E.g. Is there a way to prevent a site from overriding specific functions using devtools?

问题 I want to hover on some element, let say document.getElementById("abc") and find its hover computed style. How should I do it in Node.js using Puppeteer? 回答1: You can use the following solution to iterate and hover over certain elements to obtain the computed style: const elements = await page.$$('.abc'); const data = []; for (let i = 0; i < elements.length; i++) { await elements[i].hover(); data.push(await page.evaluate(element => window.getComputedStyle(element), elements[i])); } console

问题 I see the following anomaly in Resource Timings panel: Content Download time (from Network time) is unexpectedly high for some resource, which has been requested while loading a page: Content Download time for 1 KB is about 1 sec. although there is no network issue: I've checked that with Wireshark trace + place my browser as close to Server as it was possible.
