Phonegap Android 后退按钮 - 在主页上使用后退按钮关闭应用程序
问题描述:
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.
$.mobile.changePage("#homepage", "slideup");
}
这一切正常,但我希望应用程序仅在按下主页上的后退按钮时关闭,这可能吗?
This all works fine, but I would like the app to close when pressing the back button on the homepage only, is this possible?
答
更新:这已停止使用最新的 Phonegap 更新(据说).如果您知道,请随时提供可行的解决方案.
这是我的做法:
document.addEventListener("backbutton", function(e){
if($.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);
