google-chrome-extension

问题 I would like to create a google chrome extension. Specifically, I'd like to make a packaged app, but not a hosted app. Am I correct in thinking this limits me to JavaScript (and HTML/CSS)? My problem is that I need to do some complex math (singular value decomposition, factor analysis) and I don't want to write algorithms for this in javascript. Python already has libraries for the functions I need (SciPy), but I can't find any indication that I can make a Chrome extension using python. Is

In this code, in the console, background is displayed but datas is empty (Nothing in the console)

问题 I need a Google Chrome extension that simply disables the built in alt e shortcut and pass it to the HTML accesskey as ordinary. (yes, that all - no configuration/graphics) It's for an in-house web-application and I don't want to use existing extensions. I've browsed the extension documentation but would be thankful for a jump start in this matter. 回答1: Unfortunately there's no way to hook into global hotkeys. The best you can do is add a window event keypress listener. Source: a Chromium

问题 I have a chrome extension where a user inputs some information and it generates a report. Now of course, this report will be different each time based on what the user has entered. What I want to achieve, is for my extension to say: Hey, Mr. Background page. Here's the information you need, now build some html based off what I've given you and show it to the user. Here is the manifest.json that I'm using: { "manifest_version": 2, "name": "XXXX", "description": "XXXX", "version": "1.0.0",

问题 In my attempts to learn how to write Google Chrome extensions I decided to write one where upon clicking a button in the popup the extension opens a new window and opens a new tab for every image on the page. Each tab's url is the src for each image. (I don't think this is particularly useful, I'm doing it merely as an exercise). The weird thing is that it works exactly as I would expect when I have right-clicked on the extension icon and clicked 'inspect popup'. It doesn't work as expected

问题 I've been trying to develop a browser extension that needs to inject event handlers into all iFrames on a page. I have found that some iFrames, like those used for the Disqus commenting system, have content but no contentDocument. How is this possible, and how can I access the event handlers for an iframe without a contentDocument? Check out the comment section at the bottom of this page for an example. If you inspect the comment text area, you will see it is in an iFrame that has no
