问题 I am looking for a way to determine a given tab's opener (parent tab) within a Google Chrome extension. I've looked at the documention for Tab but there doesn't really seem to be anything that would yield this information. http://code.google.com/chrome/extensions/tabs.html I've tried injecting this content script into pages (thinking I could pass the value to my background page): alert(window.opener); .. but it just yields null. The best thing I've come up with so far is to keep track of the

问题 my Chrome extension has two files: content and background scripts. I need to add jQuery to content script from cdn and lodash to background script from cdn too. In my manifest I tried to add lodash from cdn like this: "background": { "scripts": ["background.js", "https://cdn.jsdelivr.net/lodash/4.13.1/lodash.min.js"] }, "content_security_policy": "script-src 'self' https://cdn.jsdelivr.net; object-src 'self'" But that didn't help. My content file is injected to the page from the background

问题 I have trouble loading and executing external js-script into my chrome extension. Looks the same as this question, but I still cant't figure out why it doesn't work in my case. The idea is that I want to have in my content script some default function which should parse a web-page content. And for some specific web-pages I want to load and use specific parsers, so I try to load proper js-script for a wep-page, and this script shoud extend functionality of default parser. By now I try only

问题 I am trying to detect whether my extension was uninstalled. I can't use chrome.management.onUninstalled because it will be fired on other extension. 回答1: Google Chrome, unlike Firefox, doesn’t allow to detect when the user uninstalls the extension, which is quite useful to understand user behaviour. There is a feature request on crbug.com with a discussion of this feature but it has not been implemented yet. 回答2: As of Chrome 41, you can now open a URL when the extension is uninstalled. That

问题 When i upload an update to my extension on chrome developer dashboard, it is unable to do so and it shows, An error occurred: Failed to process your item. Chrome Web Store system error, please try again later. I updated the extension version in the manifest from 0.103 to 0.104, the manifest version is unchanged (2). As i made a change that did not require any extra permission, i did not make any further changes to manifest.json. The only file changed is plugin-min.js I tested it locally on my

问题 I have recently started to see a frequent error in Chrome Dev Tools when right clicking on an element for the purposes of selecting "Inspect Element" - instead of selecting the element on the " Elements" tab the error "Uncaught Error: Parameter 2 (message) is required. " appears in the "Sources" tab for a virtual "extensions:: schemaUtils" script. The error occurs in the function "validate" as per the screenshot below. This error seems to occur since installing the "OneTab" extension, and

问题 In my extension I need to transfer some data from one tab's content script to another tab's content script. How can I choose certain tab using chrome.tabs, if I know a part of that tab object's name or url in it? How can two tabs' scripts communicate? UPDATE: Apparently I don't have method sendMessage in chrome.extension. When I run the following from content script: chrome.extension.sendMessage("message"); I get in console: Uncaught TypeError: Object # has no method 'sendMessage' 回答1: First,

问题 I am working on a google chrome extension and I am trying to load an image that is bundled with the extension into a canvas. var canvas = document.createElement('canvas'); canvas.width = 470; canvas.height = 470; var context = canvas.getContext('2d'); var image = new Image(); image.addEventListener('load', function(){ //process }); image.src = chrome.extension.getURL("asset/gotcha.png"); When I execute the code in a content script I am getting: Unable to get image data from canvas because the

问题 I want to generate a CSV file as the result of some user interactions and then prompt the user to download it. How can I do that? I don't think it's possible in straight JS, but perhaps Chrome gives me some elevated privileges? 回答1: You can now use HTML5 File API to download a file. It is still in development, but you can use a BlobBuilder and redirect your use to download that file: var bb = new BlobBuilder(); bb.append(csvContents); var blob = bb.getBlob(); location.href = window.webkitURL

问题 I'm using ACE Editor within a Chrome extension. I'm using ACE's Autocomplete feature but I want to be able to completely define a list of static strings to use for the autocomplete, instead of any local strings or snippets. (In the future I might be using something more sophisticated than a static list, but for now static is fine.) Can anyone provide some instruction on how to accomplish this? I already have autocomplete enabled and snippets off, but I'm having trouble defining a static list
