Encountering an endless loop during angular directive compilation

I am facing an issue with a directive that contains dynamic text. My goal is to be able to include ng-click directives in order to trigger functions from the text. I have learned that the recommended approach to achieve this is by compiling the HTML into a template. However, when attempting to do so, I encounter an infinite loop:

angular.module('app')
  .directive('times', ['$compile', function ($compile) {
    return {
      restrict: 'E',
      link: function postLink(scope, element, attrs) {
        scope.selectDay = function() {
          console.log("Clicked on directive");
        }

        var content = element.html("<div><span ng-click='selectDay()'>Some test content</span></div>");
        var compiled = $compile(content);
        element.append(content);
        compiled(scope);        
      }
    };
  }]);

Answer №1

To improve the way you compile, start by assigning content to the element before compiling its content with the scope:

element.html("<div><span ng-click='selectDay()'>Some example text</span></div>");
$compile(element.contents())(scope);

Answer №2

Your issue arises from compiling the wrong element after appending it to the DOM. To solve this problem, make sure to compile the new element with scope before appending it to the directive element.

CODE

angular.module('app', [])
.directive('times', ['$compile', function($compile) {
  return {
    restrict: 'E',
    link: function postLink(scope, element, attrs) {
      scope.selectDay = function() {
        console.log("Clicked on directive");
      }

      var content = "<div><span ng-click='selectDay()'>Some test content</span></div>";
      var compiled = $compile(content);
      element.append(compiled(scope));
    }
  };
}]);

To put it simply:

angular.module('app').directive('times', [
    '$compile',
    function($compile) {
        return {
            restrict: 'E',
            template: '<div><span ng-click="selectDay()">test</span></div>',
            link: function(scope, element, attrs) {
                return scope.selectDay = function() {
                    return console.log('Clicked on directive');
                };
            }
        };
    }
]);

To optimize your content creation and compilation process, follow this sequence: Firstly, create the content. Next, develop the compile function. Afterward, compile the content. Lastly, append the compiled content to the designated location. See a demo here: http://jsfiddle.net/d2ayw9vz/

Within the Angular module "app," there is a directive called 'times' that utilizes the $compile service. This directive's link function handles the click event, logging a message when triggered.

The directive also includes predefined test content wrapped in HTML tags. The content is then compiled and linked before being appended to the target element.
