If you are just using Javascript you can check how you can disable Back Button from this link:

http://jordanhollinger.com/2012/06/08/disable-the-back-button-using-html5/

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:

In your main Javascript Code (Not inside AngularJS Code or controler), put the following code:

// *** 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:

/**

 * 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.

Best Regards

Wael
