问题 I'm working on a Chrome extension and am currently trying to get my content script to automatically do a search using the form on the site. I'm doing this by changing the value of the input and then using the jQuery change() method, since the site doesn't start searching otherwise. var search = $("#videoSearchInput"); search.val("test"); search.change(); I've figured out that the change() method solves my problem by executing it through the Chrome console, but it doesn't work when I try to

问题 I was trying to develop a Chrome extension that can display me the last 3 news from a soccer news site (obviously the page is not open in any tab), by refreshing every 5 minutes.

问题 So, I'm developing a plugin for webpack for hot-reloading the chrome extensions. The biggest problem is, if I call a certain number of times the "chrome.runtime.reload()" this will make Chrome block the extension: This extension reloaded itself too frequently.
