Dynamic templateUrl - AngularJS

Question

So as of Angular 1.1.4, you can have a dynamic template url. From here,

templateUrl - Same as template but the template is loaded from the specified URL. Because the template loading is asynchronous the compilation/linking is suspended until the template is loaded.

You can specify templateUrl as a string representing the URL or as a function which takes two arguments tElement and tAttrs (described in the compile function api below) and returns a string value representing the url.

How can I utilize this to generate a dynamic template based on, say, an attribute on my directive? Obviously this doesn't work, since tAttrs.templateType is simply the string "templateType"

templateUrl: function (tElement, tAttrs) {
  if (tAttrs.templateType == 'search') {
    return '/b/js/vendor/angular-ui/template/typeahead/typeahead.html'
  } else {
    return '/b/js/vendor/angular-ui/template/typeahead/typeahead2.html'
  }
}

Given that I don't have access to the scope, how do I manage this?

Answer 1

The following is also possible for creating dynamic templates in AngularJS: In your directive use:

template : '<div ng-include="getTemplateUrl()"></div>'

Now your controller may decide which template to use:

$scope.getTemplateUrl = function() {
  return '/template/angular/search';
};

Because you have access to your scope parameters, you could also do:

$scope.getTemplateUrl = function() {
  return '/template/angular/search/' + $scope.query;
};

So your server could create a dynamic template for you.
