If you are just using Javascript you can check how you can disable Back Button from this link:
如果您只是使用 Javascript，您可以通过以下链接检查如何禁用后退按钮：

But this code above will not work well with AngularJS because AngularJS uses URL_Hash # in the background, so here i will show how you can turn around:
但是上面的这段代码不适用于 AngularJS，因为 AngularJS 在后台使用 URL_Hash #，所以在这里我将展示如何扭转：
In your main Javascript Code (Not inside AngularJS Code or controler), put the following code:
在您的主要 Javascript 代码（不在 AngularJS 代码或控制器内）中，输入以下代码：
// *** Author: Wael Sidawi
// **** Deactive Back Button ****
var history_api = typeof history.pushState !== 'undefined';
// history.pushState must be called out side of AngularJS Code
if ( history_api ) history.pushState(null, '', '#StayHere'); // After the # you should write something, do not leave it empty
And now inside your AngularJS Controler put the following event listner:
现在在你的 AngularJS 控制器中放置以下事件监听器：
/**
* Event-Listner for Back-Button
*/
$scope.$on('$locationChangeStart', function(event, next, current){
// Here you can take the control and call your own functions:
alert('Sorry ! Back Button is disabled');
// Prevent the browser default action (Going back):
event.preventDefault();
});
I hope it could help you.
我希望它能帮助你。
Best Regards
