我遇到了一个我无法解决的麻烦。
我正在尝试操纵WindowsPhone的后退按钮,但它似乎无法正常工作
我试图重新使用一个事件(实际上适用于Android应用),它更像是这样
document.addEventListener("backbutton", onBackKeyDown, false);
function onBackKeyDown(e) {
var location = window.location.href;
console.log(location);
var partial_location = location.split("#");
if (partial_location[1] == "menu/" || partial_location[1] == "login/") {
e.preventDefault();
navigator.app.exitApp();
} else {
navigator.app.backHistory();
}
}
因为它似乎不适用于Windows手机,经过一些研究我已经通过nuget WinJS安装并试图调用这样的功能
if (device.platform == "windows") {
WinJS.Application.onbackclick = function(evt){
onBackKeyDown(evt);
return true;
}
} else {
document.addEventListener("backbutton", onBackKeyDown, false);
}
我在deviceready事件中调用此事件,因此我没有解决方案。
它似乎没有检测到事件甚至是功能。所以我想知道我做错了什么。
任何消化?

我希望您已经解决了问题,如果没有,您可以尝试以下方法。
您需要在Cordova项目的index.js文件中包含backbutton()函数。
你可以实现类似于下面的内容,
var app = {
// Application Constructor
initialize: function() {
this.bindEvents();
},
// Bind event listeners for 'deviceready' and 'backbutton'
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
// Here define your back button listener
document.addEventListener('backbutton', this.handleBackButton, false);
// If you need to support native back button you can do like this
// document.addEventListener('backbutton', this.handleBackButton, true);
},
// deviceready Event Handler
onDeviceReady: function () {
//OnDeviceReady function implementation
},
// backbutton Event handler
// Here define your logics
handleBackButton: function () {
// Check if you are in home page
// You need to check according to your application. For example if the home page (data page) is index-in, show alert message
if ($('.page-on-center').data('page') == "index-in") {
myApp.confirm('Are you sure you want to exit ?', 'Exit',
function () {
// If Click EXIT or Confirm
// This is not work for me
//navigator.navigation.exitApp();
// This works fine for me
navigator.app.exitApp();
},
function () {
// If click cancel do nothing
}
);
} else {
// Go to previous page
mainView.router.back();
}
},
// do something other than the default, like undo an operation,
// or step backwards through a multi-step operation
};
