问题 I now that chrome applications can deliver an experience close to that of native applications, but I could not find a way yet to run a local command from a chrome application. Is there any API for this that could used after the user has given permission? How can this be done? Thanks 回答1: It is in principle possible via Native Messaging. You can have a native app specifically designed to talk to your Chrome app, but the downside is that the native component cannot be bundled with the app in

问题 I am puzzling my way through my first 'putting it all together' Chrome extension, I'll describe what I am trying to do and then how I have been going about it with some script excerpts: I have an options.html page and an options.js script that lets the user set a url in a textfield -- this gets stored using localStorage. function load_options() { var repl_adurl = localStorage["repl_adurl"]; default_img.src = repl_adurl; tf_default_ad.value = repl_adurl; } function save_options() { var tf_ad =

问题 I am working to create a Google Chrome Extension- in this extension, there is a popup page that uses Accordion- via Jquery UI. Now, I have correctly defined the popup.html file in manifest.json, and added the code of "start" theme of Jquery UI to the popup.html file. However when I click on the button in toolbar which should display the popup, then all sections of the accordion are being shown opened- and the accordion is not being shown at all-- all I can see is the plain text for various

问题 I'm developing a Google Chrome extension that allows you to automatically apply a highlighting CSS rule to a word that you choose. I have the following code var elements = document.getElementsByTagName('*'); for (var i=0; i<elements.length; i++) { var element = elements[i]; for (var j=0; j<element.childNodes.length; j++) { var node = element.childNodes[j]; if(node.nodeType === 3) { var text = node.nodeValue; var fetchedText = text.match(/teste/gi); if(fetchedText) { var replacedText = element

问题 This question already has answers here : Chrome Extension Message passing: response not sent (3 answers) Closed 5 years ago . I have a chrome extension that's sending a login message: chrome.runtime.sendMessage data, (response) -> debugger if response.api_key $("body").fadeOut 1000, -> window.close() else App.Ui.clearForm() App.Ui.showErrorMessage() However, the callback is never hit: chrome.runtime.onMessage.addListener (request, sender, sendResponse) -> if request and request.action is

问题 chrome.browserAction.setBadgeText(object details) is used to set the badge text for a chrome extension. However, if the tabId doesn't exist, Chrome produces the following error using console.error() : Unchecked runtime.lastError while running browserAction.setBadgeText: No tab with id: ####. This becomes a problem when the badge text is set during a page load. If the tab originally exists but is closed by the user, setBadgeText ends up being called using a non-existent tabId . Normally, this

问题 Is it possible to highlight the URL bar (set focus to the location bar) using Google Chrome extensions or Safari extensions? Using Firefox extensions, one can highlight the URL bar like this: var addressBar=document.getElementById('urlbar'); addressBar.focus(); addressBar.select(); I'm not sure if there's similar functionality in Chrome and Safari. Thanks in advance for your help! 回答1: Firefox, in its plugins and extensions gives access to browser's "chrome" (the UI stuff around the page)

问题 My extension has a context menu with items. What I'd like it to do: is when I right-click an editable html element (eg input or textarea) and then select and click on an item in my menu - some value defined by my extension gets entered into the input. For now I have realised that with document.activeElement.value = myValue . With simple inputs it works alright. Problems start when there is an input with custom onChange event handling, eg a calendar or a phone input, or currency input - that

问题 I have a Windows desktop application which must work in collaboration with my Chrome extension. Can I send a message to my desktop app somehow from Google Chrome extension? Which IPC objects can I use? 回答1: I see three options: You could use the internet. You can have a remote service that both the chrome extension and your desktop app talk to, to communicate. You could have your desktop app have a simple server built into it so that the chrome extension can make local http requests to it to

问题 I want to let the user decide when they want to run a script, so that when the browser opens, the "off" icon is showing and no script runs; but when the user clicks it, it changes to an "on" icon and executes a userscript, until the user clicks off. I have two png icons which are 32x32 each: on.png and off.png . My two questions: How can I set the default icon to my off.png? I tried this in my manifest.json but it didn't set the icon, instead showed a puzzle piece (I presume a default): ...
