Chrome扩展脚本注入到每个打开的选项卡

Question

I tried to build simple extension according to the examples: from here and here 我尝试根据示例构建简单的扩展：从这里到这里
and I must be doing something wrong here. 我在这里一定做错了。
All I want is for start that on each loading page ( or even better before loading ) it will popup hello alert 我想要的只是在每个加载页面上启动（甚至加载之前更好），它将弹出hello警报

manifest.json manifest.json

{
   "background": {
      "page": "background.html"
   },
   "content_scripts": [
    {
      "matches": ["http://*/*","https://*/*"],       
      "js": ["jquery-1.8.2.min.js","contentscript.js"],
      "run_at": "document_end"
    }
   ],
   "web_accessible_resources": [
    "script_inpage.js"
   ],
   "browser_action": {

      "default_popup": "popup.html",
      "default_title": "Test 123"
   },
   "content_security_policy": "script-src 'self'; media-src *; object-src 'self'",
   "description": "Simple Test 123.",

   "manifest_version": 2,
   "minimum_chrome_version": "18",
   "name": "Test 123",
   "permissions": [ 
        "unlimitedStorage",
        "http://*/",
        "tabs",
   ],

   "version": "2.6"
}

background.html is empty for now background.html目前为空

contentscript.js: contentscript.js：

var s = document.createElement('script');
s.src = chrome.extension.getURL('script_inpage.js');
(document.head||document.documentElement).appendChild(s);
s.onload = function() {
    s.parentNode.removeChild(s);
};

script_inpage.js: script_inpage.js：

alert("this is script");

There is no error even when I trigger the developer console window. 即使触发开发人员控制台窗口也没有错误。

Your manifest file is invalid, there's a superfluous comma after the last entry in the "permissions" section: 您的清单文件无效， "permissions"部分中的最后一个条目后面有多余的逗号：

"permissions": [ 
    "unlimitedStorage",
    "http://*/",
    "tabs", // <-- Remove that comma
],

If you want your script to run as early as possible, use "run_at": "document_start" instead of "document_end" . 如果希望脚本尽早运行，请使用"run_at": "document_start"而不是"document_end" 。 Then, your script will run before <head> and <body> even exist. 然后，您的脚本将在<head>和<body>出现之前运行。
