What is the method to deactivate the date field by using an attribute?

Question

What is the method to deactivate the date field by using an attribute?

In an attempt to disable a field using an attribute without utilizing the directive scope property, I am seeking a way to disable my field with the type 'date'.

Check out my code snippet below:

http://plnkr.co/edit/eJDRocLYkr8Krh84vFKY?p=preview

 var app = angular.module('plunker', []);

    app.controller('MainCtrl', function($scope) {
      $scope.name = 'World';
      $scope.clickb=function(){
        alert('dd')
        $scope.disabletest=true;
      }
    });

    app.directive('test',function(){
      return {
        restrict :'E',
        scope:{},
        template:'<input type="date" ng-disable="disabletest">',
        link:function(s,e,a){

        }

      }
    })

The value of the disable attribute in the directive is used to disable the field upon button click.

My goal is to use the attribute property to disable the input field of type 'date' upon clicking a button.

Here's a suggestion: Modify the ng-disable to ng-disabled, and introduce a scoped variable.

var myApp = angular.module("app",  []);

myApp.controller('ctrl', function($scope){
  $scope.disableInput = false;
  $scope.toggleDisable=function(){
    $scope.disableInput=!$scope.disableInput;
  };
});

myApp.directive('customDirective',function(){
  return {
    restrict :'E',
    template:'<input type="date" ng-disabled="disable">',
    link:function(s,e,a){
      a.$observe('disable', function(value) {
      s.disable = s.$eval(a.disable);
    });
  }
    }
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
  <button ng-click='toggleDisable()'>btn</button>
  <custom-directive disable='{{disableInput}}'></custom-directive>
</div>

Instead of using $parent, it is recommended to follow Jimbrooism's suggestion and change the scope for a better solution. The following code demonstrates how to achieve this without altering the scope:

template:'<input type="date" ng-disabled="$parent.disabletest">',
