Background.js无法使用Chrome扩展程序 [英] Background.js not working Chrome Extension

问题描述

我是铬合金扩展的新手，似乎无法弄清楚背景概念是如何工作的。我构建了一个计数器扩展，即使在用户关闭扩展（但不是浏览器）时仍然保持计数，并且想要做一个简单的测试，看看我是否可以弄清楚如何使用背景文件。以下是我尝试创建一个函数，该函数每次用户点击一个选项卡（我的扩展名之外）时激活，并且当他们单击5个选项卡时，会弹出警报。我不明白为什么这不起作用。

background.js：

  var counter = 0; 
 chrome.browserAction.onClicked.addListener（function（tab）{
 counter ++; 
 if（counter == 5）{
 alert（Hi）; 
 } 
}）; 
  

manifest.json：

  {
name：Hello World！，
description：我的第一个打包应用程序。，
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
}，
图标：{
16：icon16.png，
48：icon48.png，
128：icon128.png
 
 
 
 $ div $解析方案

它是以下面的代码为我工作。

manifest.json

  { 
name：Popping Alert，
descrip和：http://stackoverflow.com/questions/15194198/background-js-not-working-chrome-extension，
background：{
scripts：[
background.js
] 
}，
version：1，
manifest_version：2，
browser_action：{
default_title：点击我
} 
} 
  

背景.js

  var counter = 0; 
 chrome.browserAction.onClicked.addListener（function（tab）{
 counter ++; 
 if（counter == 5）{
 alert（Hey !!! You have clicked five次）; 
} 
}）; 
  

如果这不起作用，您可以分享您的相关代码或清楚列明问题陈述吗？

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.

background.js:

var counter = 0;
chrome.browserAction.onClicked.addListener(function(tab){
  counter++;
  if (counter == 5) {
    alert("Hi");
  }
});

manifest.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"
  }
}

解决方案

It is working for me with following code.

manifest.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

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?
