问题 Upon receiving a message from a content script I want to create a new tab and fill the page it opens dynamically (for now I'm just trying to turn the newly created page red). eventPage.js: // ... code that injects another content script, works fine // Problem code... chrome.runtime.onMessage.addListener( function(request, sender, sendResponse) { chrome.tabs.create({url: chrome.extension.getURL("blankpage.html")}, turnTabRed); }); function turnTabRed(tab) { chrome.tabs.executeScript( tab.id,

问题 I know that waiting for an asynchronous method is stupid, one should use callbacks instead. But what if an third party API forces you to be synchronous? I'm developing a Chrome Extension that will prevent the user from visiting websites that's already open in another tab. I basically need to cancel requests based on the urls in open tabs. I want to use chrome.webRequest.onBeforeRequest like this: function onBeforeRequest(details) { var websiteAlreadyOpenInOtherTab; // Here i want to set

问题 I'm re-posting my question from Chromium-extensions google group here. In my extension, I want to cancel some webRequests based on url pattern. My problem is that, if I return {cancel:true} in the onBeforeRequest event listener, the browser would redirect to a page telling me that the request is blocked by some extension. But I just want to cancel the request silently(as nothing happened). I have also tried to return {redirectUrl:""} in the onBeforeRequest event listener, the console would

问题 For a Google-Chrome extension, I would like to load a content script on all Google pages. What is the best way to do this? I tried this, in the manifest.json , but it does not work: "matches": ["http://www.google.*/*", "https://www.google.*/*"], This "works" but it is a bit long to write and I do not think it is the best practice: "matches": ["http://www.google.com/*", "https://www.google.com/*", "http://www.google.fr/*", "https://www.google.fr/*", "http://www.google.de/*", "https://www

问题 With 'Native Messaging' it should be possible to communicate between a chrome extension and a native app. https://developer.chrome.com/extensions/nativeMessaging Google even provides an example for how to do this with a python "host"-app: https://chromium.googlesource.com/chromium/src/+/master/chrome/common/extensions/docs/examples/api/nativeMessaging/host/native-messaging-example-host I wanted to use this technique to communicate between a Sublime Text plugin (python) and an Chrome extension

问题 It's very strange. 1 problem If I add this icon declaration to my manifest: "icons": { "16": "images/icon16.png", "48": "images/icon48.png", "128": "images/icon128.png" }, Then, when I add Extension through "Load unpacked extensions ... " it doesn't show logo But if you try to delete it, it does show AND! If I delete "48" line from manifect, it starts showing it right away. Maybe it's because I use Chrome Beta (Version 28.0.1500.20 beta) or maybe because I do something wrong. Seconds problem

问题 I am trying to set the extension icon to a canvas image. I can't seem to get it to set. I just want to get the basics working and expand from there. I can set the icon with an image in the file structure but I want to be able to dynamically update the text later. I tried a few ways to get chrome.browserAction.setIcon to set to no avail. I hope it is not something simple I am missing. Thanks //chrome.browserAction.setIcon({imageData: draw()}); draw(); function draw() { var canvas = document

问题 I can create static theme as described in documentation which I guess can not be modified at runtime. I need some way or API for changing theme properties at runtime. Is it possible to do it with Chrome? 回答1: No, it's not possible right now. Sorry 来源： https://stackoverflow.com/questions/12420652/is-it-possible-to-create-dynamic-theme-in-chrome

问题 I'm making a Chrome extension that involves putting a text input on the new tab page, and immediately giving focus to that input text when the new tab page loads. After being unable to get focus using traditional methods (e.g. focus() ), I stumbled upon this question: Chrome 27: New Tab Page extension can't steal focus from Omnibox which states that Chrome has now made it so that you can't steal omnibox focus on a new tab page. Given that Chrome is fine with giving focus to any site that isn

问题 In my chrome extension's content script, I click on certain links/buttons on webpages from certain sites. To do that, I use following code in the content script (I embed jQuery in the content script): $(css_selector).trigger("click") This works on most sites. However, on certain sites like delta.com, match.com, and paypal.com, this way of triggering a click on elements does not work. On delta.com, I get following exception thrown when I attempt triggering in the content script: Error: An
