Background.js not working Chrome Extension
提问by user1987920
I'm new to chrome extensions and cannot seem to figure out how the background concept works. I am building a counter extension that keeps counting even when the user closes the extension (but not the browser) and wanted to do a simple test to see if I could figure out how to use the background file. Below is my attempt to create a function that activates everytime a user clicks on a tab (outside of my extension) and when they click on 5 tabs, the alert hits. I cannot figure out why this doesn't work.
我是 chrome 扩展的新手，似乎无法弄清楚背景概念是如何工作的。我正在构建一个计数器扩展程序，即使用户关闭扩展程序（但不是浏览器），它也会继续计数，并想做一个简单的测试，看看我是否能弄清楚如何使用后台文件。下面是我尝试创建一个功能，每次用户单击选项卡（在我的扩展程序之外）时都会激活该功能，并且当他们单击 5 个选项卡时，警报会触发。我无法弄清楚为什么这不起作用。
background.js:
背景.js：
var counter = 0;
chrome.browserAction.onClicked.addListener(function(tab){
counter++;
if (counter == 5) {
alert("Hi");
}
});
manifest.json:
清单.json：
{
"name": "Hello World!",
"description": "My first packaged app.",
"version": "0.1",
"permissions": ["tabs", "http://*/*"],
"manifest_version":2,
"content_scripts": [ {
"js": [ "jquery-1.9.1.js", "myscript.js" ],
"matches": [ "http://*/*", "https://*/*"]
}],
"background": {
"scripts": [
"background.js"
]
},
"browser_action": {
"default_title": "10,000 Hours",
"default_icon": "icon16.png",
"default_popup": "index.html"
},
"icons": {
"16": "icon16.png",
"48": "icon48.png",
"128": "icon128.png"
}
}

It is working for me with following code.
它使用以下代码对我来说有效。
manifest.json
清单文件.json
{
"name": "Popping Alert",
"description": "http://stackoverflow.com/questions/15194198/background-js-not-working-chrome-extension",
"background": {
"scripts": [
"background.js"
]
},
"version": "1",
"manifest_version": 2,
"browser_action": {
"default_title": "Click Me"
}
}
background.js
背景.js
var counter = 0;
chrome.browserAction.onClicked.addListener(function (tab) {
counter++;
if (counter == 5) {
alert("Hey !!! You have clicked five times");
}
});
Can you share your related code or put your problem statement clearly if this does not work?
如果这不起作用，您能否分享您的相关代码或清楚地说明您的问题？
