问题 I would like to debug what the background script (non persistent) does when it goes to sleep and wakes up (and goes back to sleep again). Clicking on the "background page" will prevent the background script from going into suspended state, but if I kill the page and open it after a while, only fresh logs are displayed, not the ones that were printed before opening the background page (from the extensions page). So I am wondering how do we debug the suspended/wake states of an event page? Edit

问题 I've found this great extension which does exactly what I want in terms of functionality e.g it switches the hidden input fields and makes them visible. The only thing I've been trying to figure out is how to make it so it will work as an extension icon button and not as a shortcut key combination?. Extension: https://chrome.google.com/webstore/detail/hidden-field-switcher/gfkfklknjmlpldiggcjgdgkonoicfngp Thanks My Current Setup: I've been able to add the button but on click it doesn't do

问题 I'm writing a chrome extension to save images found on a webpage to dropbox. I'm trying to use the dropin saver api to do this, however I am getting an error when the "save to dropbox" link is being clicked. The error I receive is as follows: {"error": "Origin does not match any app domain"} An examination of the GET request reveals the following: GET https://www.dropbox.com/saver?origin=chrome-extension%3A%2F%2Fogmklfknlcgklhfljkcijikghbnghcal&app_key=MYDROPBOXKEY 403 (OK) The error and the

问题 I've managed to get the element of a button inside a a webpage . I know its ID , its class , etc ; I even managed to trigger the click event from within a content script from a Google Chrome extension . The button is inside a Google webpage. There's a Browse button though that opens up a openDialog window and prompts the user to chose a certain file for uploading. How can I go on automating this upload without prompting the user for the file? I just want to feed it the string from the content

问题 I've been using websockets without an issue for months to communicate between Chrome and my localhost app. Suddenly, with the latest version of Chrome, data is not going through cleanly. In the Chrome extension's javascript, the relevant part of the code is: window.ws = new WebSocket("ws://localhost:13000/"); window.ws.onopen = function () { window.ws.send('GO'); In my C# app: string msg = ASCIIEncoding.UTF8.GetString(buffer); Debug.WriteLine(msg); For months this worked fine and I would get

问题 I'm trying to build a Chrome app and/or extension to communicate with a serial device (using https://developer.chrome.com/apps/serial), to use for showing data from the device on a webpage. I've created an app that can read messages from my device but I now need to get those messages to my webpage. My plan was to create an extension that communicates with my app and then updates my webpage. My extension sends messages to the app using "chrome.runtime.sendMessage" and my app then responds with

I've downloaded it from here: https://developer.chrome.com/extensions/nativeMessaging#examples I've registered the host. I've installed the extension. I've verified the ID's match.

问题 I'm making a text replacing extension (of sorts) using the method described here as a basis for replacing text. Here is the important piece of 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 replacedText = text.replace(/[word or phrase to replace here]/gi, '[new word or

问题 In one of my components, when the component is loaded, I want my extension to inject a script into the current tab that the extension is run on. The script essentially gets the source code and save it as a string. So, in my componentWillMount I tried to inject the script in the following way... componentWillMount() { var result = ''; chrome.tabs.executeScript(null, { file: './js/scripts/getPageSource.js' }, function() { // If you try and inject into an extensions page or the webstore/NTP you
