问题 I'm brand new to making Chrome Extensions and have done the simple tutorials, but I'm having trouble finding what I need. I want the extension to allow a user to chose an image on a webpage, and then copy the URL for that image into the extension. Can anyone help me out? I'm sure if I see an example I'd get a better grasp on how extensions can interact with a page. 回答1: From what I understand of your question, I'd say you want to create a context menu item that shows up when you right-click

问题 I am new to this chrome extension plugin development. I am developing a new new plugin using this chrome extension. My requirement is load jquery.js file into the content script when it is not having that js file(For Ex: I am checking for jquery.js file,fancybox.js file and if it is not there load these files. ) When i implement this logic in content script it is loading the jquery.js file. After that it is not working in content script . It is showing $(or) jQuery is undefined. For every

问题 I am using sendMessage and onMessage listener (both in background and content pages), and I am seeing some messages are getting lost. I have a few "global" variables that I store everytime I go to suspend state, and restore them among the first things when the script starts (I register the handlers first). However, given that the chrome.storage is asynchronous, I suspect message processing is happening before I get to load the global state (and hence the appearance of losing the messages).

问题 Is it possible to use the chrome.system.cpu api to get the current CPU load? I specifically can't figure out how to convert the returned numbers to a percent of the total current load. I found this, but not quite sure how to implement: "Callers can compute load fractions by making two calls, subtracting the times, and dividing by the difference in totalTime." https://developer.chrome.com/apps/system_cpu Answer : An example of getting CPU usage is here: https://github.com/beaufortfrancois/cog

问题 I need some advice about Chromium extension possibilities. Can the extension change configs of the browser such as: home page, default behavior for protocol handlers (tel, mailto), security settings ("protect from dangerous websites" for example), disable sending statistics to Google, etc.? Which configs from chrome://settings/ can be changed and how to do it if it's possible? 回答1: The Chrome API index is a good place to start. From it, you can glean the following capabilities:

问题 I'm pretty new on chrome extensions and so far, I could manage to get the current tab title and mouse positions, however, I've made some searches and couldn't find a way to get the element attributes, such as "e.target.innerText" when I click on them, right click and get a new option, anything from a mouse input, does anyone knows how to do so? This is what my popup.js looks like window.onclick = e => { chrome.extension.getBackgroundPage().chrome.tabs.executeScript(null, { code:'chrome

问题 I am making a Chrome extension and want to implement a plugin mark.js (https://markjs.io/) that would highlight text on the user page. However, I am having trouble importing the plugin. Since the html is the user's page and I don't have access to it, I can't use the usual <script></script> . So, I tried to use JavaScript to do it, but am still getting an error. My JavaScript code is as follows: var head= document.getElementsByTagName('head')[0]; var script= document.createElement('script');

问题 My chrome extension is very simple. After the popup is clicked an iframe is loaded. The chrome extension is slightly slow. I click the icon and it takes about a second and a half to load, and I feel like that is too slow. I'd like the popup to show instantly but have the iframe load after.. or perhaps there is an even quicker way... The site that I am iframing only has a textbox visible so in theory the popup should load pretty quickly but I'm just not getting it. My manifest file basically

问题 INITIAL QUESTION: Is it possible to run javascript from Chrome's Console that will: Navigate to a given URL Click a button I'd like to repeat the above steps for hundreds of URLs. I'm sure if I get the two steps working iterating over a number of URLs will be fairly straightforward. So, I've made Console persistent between page refreshes, so that's a good start...but it seems the Click event it not being triggered. The clicking command works fine if I manually navigate to the URL then run it
