问题

I'm attempting to dynamically add an attribute Directive to a transclude directive.

For example, the template would start off as follows:

<div class="container">
  <div ng-transclude></div>
</div>

After an event takes place (eg. a click), it would then have an attribute Directive added, such as:

<div class="container" some-directive>
  <div ng-transclude></div>
</div>

I'm using the following JavaScript to do this:

div = angular.element("#demoParentDirective .container").clone();
div.attr('some-directive','');
div = $compile(div)($scope);
angular.element("#demoParentDirective .container").replaceWith(div);

However, this results in:

Error: [ngTransclude:orphan] Illegal use of ngTransclude directive in the template! No parent directive that requires a transclusion found. Element: <div ng-transclude="">

I've created a stripped down demo of what I'm trying to do in Plunker to show how I'm doing it:

Any help would be appreciated. Thanks.

Update:

As requested, I've created a follow-up question asking if there is a better way to achieve what it is I'm trying to achieve:

Adding transclude to your child directive fixes the issue in your Plunk

angular.module('demo')
.directive('demoChildDirective', function() {
    return {
      restrict: "A",
      priority: 500,
      transclude: true,
      link: function(scope, element, attributes) {
        console.log("Child Directive Applied.");
      }
    }
  });
