Is there a way to inject a scope variable into the `tAttrrs` object of a directive?

Hey there, I have a question about using a scope variable in a dynamically generated template URL. Here's what I tried:

HTML

<my-directive type="{{ type }}"></my-directive>

JS

angular.module('myApp', [])
  .directive('myDirective', function () {
    return {
      templateUrl: function (tElement, tAttrs) {
        return 'templates/myDirective.' + tAttrs.type + '.html';
      };
    };
  });

I thought tAttrs.type would give me the value of $scope.type, but it actually returned {{ type }}. This resulted in a templateUrl of

templates/myDirective.{{ type }}.html
.

Any suggestions on how to get the actual value of the scope variable instead of the raw text?

Answer №1

Directives' templateUrls do not have access to scope values as the attributes are not compiled yet within that context. Therefore, accessing the scope is not possible from there.

If you're facing this issue, here's a helpful workaround that may solve it for you.

To bypass this limitation, I utilized a template with a div including ng-include and acquiring the URL via a two-way bind mechanism.
