google-chrome-extension

问题 I'm getting started on my first extension using the Chrome tutorial and got tripped up almost immediately. Says to click Load Unpacked and then select the file path to the manifest file. However, when I click Load Unpacked nothing shows up; no file explorer or even an error message. There's no change to the screen. Any understanding on why this might be happening? 来源： https://stackoverflow.com/questions/58697679/load-unpacked-chrome-extension-not-working

问题 This question is a follow-on to another question which needed asking and warranted a new post, so excuse me if I refer to things which may not be clear without reading the other question. When using the utility waitForKeyElements() I'm facing an issue in which a div is included inside a small popup contained within the same URL. My extension is currently running on the Twitter site, and my intention is that a div contained on the profile pages (e.g. http://twitter.com/todayshow) gets moved

问题 I'm try to develop a simple google chrome extension. What it does it that it displays the number of downloads on a page (the count) and display it in a popup. The page in question that needs monitoring is a page which can only be acessed after logged in. So I need to basically use html and javascript to 'scrap' the count number from the page and display it in a popup. So far I have created the barebones of the exntension: { "name": "Downloads Logger", "version": "1.0", "manifest_version": 2,

问题 I'm trying to create a chrome extension that pops up a small input when a user highlights text on the page (similar to Medium's tweet on text highlight feature). I'm progressing but would find it much easier to use jQuery (rather than vanilla JS and XHRs). I've seen a few posts about requiring jQuery in the manifest, and I've tried it many different ways without success. I have a manifest(below), a contentscript.js and dropdown.js(the file I want to inject onto the page). { "name": "na",

问题 Is it possible to initiate a TCP connection from a browser? If so, does there already exist browser (esp. Firefox and Chrome) extensions that do this? If no extensions exist yet, do you know the core elements/functions to create a Firefox/Chrome browser-initiated TCP connection? 回答1: The Chrome Browser (I think since v24 in the stable channel) lets you host a TCP server, and the samples indicate that it can connect to a telnet server, which means that it is also capable of being a TCP client.

问题 I am trying to set, and later request the data stored locally in an extension The way I am doing this is sending a request from the content script as follows chrome.runtime.sendMessage({method: "fetchData"}, doSomething) On the background page, the message is received and parsed by: chrome.runtime.onMessage.addListener(getData); where getData is a function as follows: var getData = function(message, sender, sendResponse) { if (message.method == "fetchData"){ chrome.storage.local.get('myinfo'
