angularjs - Angular: ng-bind-html filters out ng-click?

Question

I have some html data that I'm loading in from a json file.

I am displaying this html data by using ngSanitize in my app and using ng-bind-html.

Now I would like to convert any links in the json blob from the standard

• <a href="some_link">link</a>

to:

• <a ng-click="GotoLink('some_link','_system')">link</a>.

So I'm doing some regExp on the json file to convert the links, but for some reason however ng-bind-html is filtering out the ng-click in it's output, and I can't figure out why. Is it supposed to do this, and if so is it possible to disable this behavior?

Check out this jsFiddle for a demonstration: http://jsfiddle.net/7k8xJ/1/

Any ideas?

Ok, so the issue is that it isn't compiling the html you include (angular isn't parsing it to find directives and whatnot). Can't think of a way to make it to compile from within the controller, but you could create a directive that includes the content, and compiles it.

So you would change

<p ng-bind-html="name"></p>

to

<p compile="name"></p>

And then for the js:

var myApp = angular.module('myApp', ['ngSanitize']);
angular.module('myApp')
.directive('compile', ['$compile', function ($compile) {
  return function(scope, element, attrs) {
    scope.$watch(
      function(scope) {
        return scope.$eval(attrs.compile);
      },
      function(value) {
        element.html(value);
        $compile(element.contents())(scope);
      }
   )};
  }]).controller('MyCtrl', function($scope) {
    var str = 'hello http://www.cnn.com';
    var urlRegEx = /((([A-Za-z]{3,9}:(?://)?)(?:[-;:&=+$,w]+@)?[A-Za-z0-9.-]+|(?:www.|[-;:&=+$,w]+@)[A-Za-z0-9.-]+)((?:/[+~%/.w-]*)???(?:[-+=&;%@.w]*)#?(?:[.!/\w]*))?)/g;
    result = str.replace(urlRegEx, "<a ng-click="GotoLink('$1','_system')">$1</a>");
    $scope.GotoLink = function() { alert(); }
    $scope.name = result;
});
