问题 I'm trying to have it so that my content script runs on every site except for 3. I know there's probably a way to do it with regex but I'd prefer not to. Does the chrome extension manifest allow for exceptions? If regex is the only solution and anyone knows the pattern to exclude these 3 URLs that would be great too. https://www.linkedin.com/ https://mail.google.com/ https://twitter.com/ 回答1: https://developer.chrome.com/extensions/content_scripts lists an option exclude_matches : "content

问题 I am building a Google Chrome browser extension that uses $.ajax requests to send data from webpages to my server (currently hosted using localhost). The content_script.js file that is being executed in the context of the webpages (more on content scripts) that the extension has access to runs this code: //note: encode64String is assigned earlier in the script... $.ajax({ type: "POST", url: "http://localhost:8888/quartzsite/uploadendpoint.php", type: "jsonp", data: {img: encode64String},

问题 What are the differences between chrome.runtime.getURL and chrome.extension.getURL?
