我试图禁用我的科尔多瓦应用程序中的后退按钮。

我发现这个主题,并试图在code波纹管,但是它绝对没有任何影响。任何想法?
谢谢!
I'm trying to disable the back button on my Cordova app. I'm using AngularJS + Ionic Framework. I found topics about this and tried the code bellow, but it has absolutely no effect. Any idea? Thanks!
index.html的
index.html
<head>
<script>
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
document.addEventListener("backbutton", function (e) {
e.preventDefault();
console.log("hello");
}, false );
}
</script>
</head>
请注意,当我按下后退按钮,我有你好显示在我的控制台。
Note that when I push back button, I have "hello" displayed in my console.
推荐答案
终于找到了对离子论坛线程答案:
Finally found the answer on Ionic Forum thread:
<一个href=\"http://forum.ionicframework.com/t/handling-the-hardware-back-buttons/1505/7\">http://forum.ionicframework.com/t/handling-the-hardware-back-buttons/1505/7
$ionicPlatform.registerBackButtonAction(function () {
if (condition) {
navigator.app.exitApp();
} else {
handle back action!
}
}, 100);
$ ionicPlatform.registerBackButtonAction允许完全地覆盖后退按钮行为。
第一个参数是一个回调函数和secondone优先级(仅具有最高优先级被执行回调)。
$ionicPlatform.registerBackButtonAction allows to completly overwrite back button behavior. First param is a callback function and the secondone a priority (only the callback with the highest priority gets executed).
