There is $document in angular js:

angular.module('yourModule', [])
  .controller('yourController', ['$scope', '$document', function($scope, $document) {
      $document.on('keydown', function(e){
          if(e.which === 8 && ( e.target.nodeName !== "INPUT" && e.target.nodeName !== "SELECT" ) ){ // you can add others here inside brackets.
              e.preventDefault();
          }
      });

    }
  ]);

Plnkr Demo.

You can see in the demo i have used only for "INPUT" nodeName and it does not prevent the default of the backspace key on text input but not on textarea because we have not handled it in the condition.
