Question

我正在尝试制作广告拦截扩展程序。这是代码：

的manifest.json：

    {
   "manifest_version":2,
   "name":"Ad Killer",
   "description":"A Basic program for blocking ads",
   "version":"0.7",
   "permissions": ["activeTab"],
   "background":{
      "scripts":[
      "background.js"]
   },
   "content_scripts":[
      {
         "matches":[
            "<all_urls>"
         ],

         "run_at" :"document_end",

         "js":[
            "jquery-3.2.1.min.js",
            "content.js"
         ]
      }
   ],
   "applications":{
      "gecko":{
         "id":"{99f660be-10c4-4cc8-9205-72dd45f156b9}"
      }
   },
   "browser_action":{
      "default_icon":"ad128.png",
      "default_title":"Ad Killer"
   }
}

restore.js几乎为content.js，但所有隐藏属性均为false。

and background.js：

var enable = false;
enable = enable ? false : true;
chrome.browserAction.onClicked.addListener(function (tab) {
    enable = enable ? false : true;
    if(enable){
    chrome.browserAction.setBadgeText({ text: 'ON' });
    //location.reload();
     chrome.tabs.executeScript(null, { file: 'content.js' }); 
} else {
    enable = false;
    chrome.browserAction.setBadgeText({ text: 'OFF' });
    //chrome.tabs.executeScript(tab.id, {code:"location.reload(false);"});
    chrome.tabs.executeScript(null, { file: 'restore.js' }); 
    }
});

这一切都很好，但我想做一件事。每次用户访问新标签页（chrome://newtab）时，我希望脚本停止运行并将切换状态更改为OFF。每当扩展程序在网站中时，我希望它默认为ON。有谁知道如何实现这一目标。非常感谢任何帮助。

您可以使用ActiveTab Permission访问当前关注的标签，并最终针对您需要的网站测试标签网址/主机名，然后采取相应措施。 注意：使用“all_urls”是一个坏习惯另一个解决方案正在使用"tabs" 并且一旦列出了确切的网址/网站权限，您的扩展程序将仅在具有给定网址的标签上激活。

停止并开始在某个网站
