问题 I am developing a chrome extension that uses jQuery/Zepto in the content script. Now, the extension is meant to run on every website, which means a copy of jQuery/Zepto is loaded on each tab the user opens. Is there a way to share the jQuery/Zepto object between the various content scripts? I know content scripts can communicate with the background script. I was hoping to be able to let the background script have access to the jQuery object and return a reference to it, to each of the content

问题 I am working on a Chrome extension that needs to inject scripts into data:-URI pages.

Also the activeTab permission did not do the trick. Any ideas? 回答1: It's currently a

问题 $x("//a[contains(@href,'.jpg')]"); works as expected from the developer tools command prompt. But, when in an extension's content-script I get a ' $x is not defined '. Why is this not available in a content-script or is there a special way of accessing it inside a content-script / Chrome extension? I'm using Chrome 22 on Debian. 回答1: $x() is not part of the run-time environment of a web page or content script. It is a tool that is part of the Command Line API for Chrome's DevTools. To use

So, I could just define what pages said CSS file would work on and then it would take effect just like a contentscript. I understand that it is possible to add CSS through a JavaScript file, but it would be more convenient to do it this way instead if possible. If it's not possible, then of course I must use contentscript, but I would first like to know

问题 I've looked everywhere for how to capture touch pad input for laptops but I can't seem to find anything for Chrome extensions/JavaScript. Question: how can I capture the number of fingers down (not clicked, just down and potentially moving as you would with a mouse), their corresponding x,y coordinates, and their corresponding up events, for a touch pad on a laptop?
