Phonegap Android Back Button - 在主页上关闭带有后退按钮的应用程序

  Update: this has stopped working with a latest Phonegap update (supposedly). Feel free to offer a working solution if you know it.

  我是这样做的：

  document.addEventListener("backbutton", function(e){
      if($.mobile.activePage.is('#homepage')){
          /* 
           Event preventDefault/stopPropagation not required as adding backbutton
            listener itself override the default behaviour. Refer below PhoneGap link.
          */
          //e.preventDefault();
          navigator.app.exitApp();
      }
      else {
          navigator.app.backHistory()
      }
  }, false);
  

  有关详细信息，请在此处找到相关文档以及完整示例：http://docs.phonegap.com/en/2.0.0/cordova_events_events.md.html#backbutton

  document.addEventListener("deviceready", onDeviceReady, false);
  function onDeviceReady() {
      document.addEventListener("backbutton", onBackKeyDown, false);
  }
  function onBackKeyDown() 
  {
   navigator.app.exitApp();
  }
  

  谢谢spader .

  您需要跟踪主页的显示时间 . 如果您知道自己正在主页上致电：

  navigator.app.exitApp();

  如果您不想使用jQuery Mobile，请在@Spadar上将 $.mobile.activePage.is('#homepage') 更改为 document.getElementById('#homepage') 关闭答案，如下面的代码所示：

  document.addEventListener("deviceready", onDeviceReady, false);
  
      function onDeviceReady(){
          document.addEventListener("backbutton", function(e){
             if(document.getElementById('#homepage')){
                 e.preventDefault();
                 navigator.app.exitApp();
             }
             else {
                 navigator.app.backHistory()
             }
          }, false);
      }
  

  通过这种方式，不需要为此目的下载Jquery Mobile乱码 . Also, activePage is deprecated as of JQuery mobile 1.4.0并将从1.5.0中删除 . （Use the getActivePage() method from the pagecontainer widget instead）
