addEventListener not triggering when used in a chrome extension

由 瘦欲@ 提交于 2020-04-08 10:32:15
问题 I'm trying to make a chrome extension that will search different cache databases for a given page. However, it's not working as I expect it to. <!DOCTYPE HTML> <html> <head> <script type="text/javascript"> var x; var img = document.getElementsByTagName("img"); for(x in img) { img[x].addEventListener('click',openPage, false); } function openPage(event) { alert("clicked"); var e = event.target; switch(e.alt) { case "WayBack Machine": chrome.tabs.update(tab.id, { url: "http://wayback.archive.org

chrome.runtime.onMessage response with async await

由 心不动则不痛 提交于 2020-04-07 18:44:28
问题 I want to use async await in an onMessage listener: chrome.runtime.onMessage.addListener(async (request, sender, sendResponse) =>{ var key = await getKey(); sendResponse(key); }); However I get undefined when I send a message. From the documentation for chrome.runtime.onMessage.addListener: This function becomes invalid when the event listener returns, unless you return true from the event listener to indicate you wish to send a response asynchronously (this will keep the message channel open

Why is the response body empty (0 bytes on network tab) for this request? Is it to do with this being an extension?

问题 When I use the fetch API (Or xmlhttprequest) I get a 0 byte response. Here is a sample of my code: fetch("https://myurl", { method: "POST", headers: { 'Accept': 'application/json', 'Content-Type': 'application/json' }, body: JSON.stringify({content: content}) }).then(function(res){ return res.text()}).then(function(res){ return cb(res);}); In the network tab, and in the console.log(res) in the callback, the response is empty. I should note that the response is including a CORS response

Chrome Extension Shortcuts

由 旧城冷巷雨未停 提交于 2020-03-23 12:09:07
问题 I'm writing a simple extension that has a .js file with only 2 functions and a listener (which only writes to Console - but I can't see it and not sure it catches anything). I'd like to have shortcuts assigned, let's say Ctrl+Shift+1 and Ctrl+Shift+2 to both functions. I'm not exactly sure how to do it, and if it's possible. The data I've been able to gather online didn't cover what I'm looking for. I have no need for html popup. All I want is to press the shortcut and have the correspondent

Chrome addon is randomly sending trash to my c++ native host application

问题 I'm trying to write a simple parental control app for my university project, but I'm a newbie in browser addons. I want to use Chrome addon to send hosts viewed by the user in real-time to Qt app, which will analyze the user behavior.
