Rendering html in Angular with Directive

Question

I am storing html data in my database from the output of a WYSIWYG editor. The html also stores the html for some directives. One of them being the ui-bootstrap tooltip:

<span tooltip-placement="left" tooltip="On the Left!">Tooltip text here</span>

I am able to get any other html elements to work by using the binding:

<div ng-bind-html-unsafe="html.content"></div>

But the html with the directive's reference doesn't interact with the actual directive.

How can I get the directive to work?

Do I have to compile the html or something like that?

Yes, since the markup you are trying to render contains directives, you need to compile it so they are processed by Angular.

You could create a directive that does that for you:

app.directive('htmlRender', function($compile) {
  return {
    restrict: 'E',
    scope: { html: '@' },
    link: function(scope, element) {
      scope.$watch('html', function(value) {
        if (!value) return;

        var markup = $compile(value)(scope);
        element.append(markup);
      });
    }
  };
});

Plunker here.

Yes You need to complile the HTML as Angular will only consider as below as simple html

<div ng-bind-html-unsafe="html.content"></div>

Check below is documentation for $compile

I managed to make a simple directive that compiles the html value that it is given, and then simply places that content within the element - the compile documentation was very useful in this regard – Sneaksta Sep 12 '13 at 06:12
