我正在使用Jquery Mobile / Phonegap开发一个Android应用程序。我有以下代码来控制手机的后退按钮：

I am developing a Android app using Jquery Mobile/Phonegap. I have the following code to control the phone's back button:

document.addEventListener("backbutton", backKeyDown, true); function backKeyDown() { // Call my back key code here. $.mobile.changePage("#homepage", "slideup"); }

这一切都很好，但我想应用程序关闭时按

This all works fine, but I would like the app to close when pressing the back button on the homepage only, is this possible?

推荐答案

这是我的操作方式：

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);
