【问题描述】:
我正在使用 cordova 创建混合移动应用程序,我对此并不陌生。
如果用户在主页单击两次后退按钮,我想退出 Android 应用程序,但我无法处理后退按钮功能。
谁能告诉我如何处理特定页面的后退按钮功能
这是我的 index.html

<body>
<div id="main" data-role="page">
<div class="app">
<h1>Apache Cordova</h1>
<div id="deviceready" class="blink">
<p class="event listening">Connecting to Device</p>
<p class="event received">Device is Ready</p>
</div>
</div>
</div>
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="js/index.js"></script>
</body>
</html>
这是我的 Index.js:
var app = {
// Application Constructor
initialize: function() {
this.bindEvents();
},
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
document.addEventListener("backbutton", function() {
if ( $('.ui-page-active').attr('id') == 'main') {
exitAppPopup();
} else {
history.back();
}
}, false);
},
onDeviceReady: function() {
app.receivedEvent('deviceready');
},
// Update DOM on a Received Event
receivedEvent: function(id) {
var parentElement = document.getElementById(id);
var listeningElement = parentElement.querySelector('.listening');
var receivedElement = parentElement.querySelector('.received');
listeningElement.setAttribute('style', 'display:none;');
receivedElement.setAttribute('style', 'display:block;');
console.log('Received Event: ' + id);
},
function exitAppPopup() {
navigator.notification.confirm(
'Exit PhoneGap ' + device.cordova + ' Demo?'
, function(button) {
if (button == 2) {
navigator.app.exitApp();
}
}
, 'Exit'
, 'No,Yes'
);
return false;
}
};
app.initialize();
【问题讨论】:
-
控制台有错误吗?
-
控制台没有错误。我已经按照链接进行操作-->ventusmoso.com/phonegap/jquerymobile/… 教程但是。我没有得到任何答案
-
尝试发出警报并测试它正在破坏的地方......
