问题描述
我正在尝试禁用我的 Cordova 应用程序上的后退按钮.我正在使用 AngularJS + Ionic 框架.我找到了关于这个的主题并尝试了下面的代码，但它绝对没有效果.有什么想法吗?
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?
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，当我按下后退按钮时，控制台中会显示hello".
Note that when I push back button, I have "hello" displayed in my console.
推荐答案
终于在this 离子论坛主题:
Finally found the answer on this Ionic Forum thread:
$ionicPlatform.registerBackButtonAction(function () {
if (condition) {
navigator.app.exitApp();
} else {
handle back action!
}
}, 100);
$ionicPlatform.registerBackButtonAction 允许完全覆盖后退按钮行为.第一个参数是回调函数，第二个参数是优先级(只有优先级最高的回调才会被执行).
$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).
