[AngularJS]20. Element Directive

Instead of using ng-include, lets create a custom directive called productDescription.

Create an Element Directive for our Description div that includes the product-description.html.

  app.directive('productDescription', function(){
    return{
      restrict: 'E',
      templateUrl: 'product-description.html'
    };
  });

 

Include the file on the page using a custom directive tag instead of ng-include.

<product-description ng-show="tab.isSet(1)"></product-description>

to replace:

          <div ng-show="tab.isSet(1)" ng-include="product-description.html">
          </div>

 

Be careful: in js, the directive named 'productDescription', but in HTML it should be 'product-description'.
