Heres my directive code:

Answer 1

If not put it in the markup.

<div headermenu template="../assets/common/headerMenu{{user_role}}.html" />
<headermenu template="../assets/common/headerMenu{{user_role}}.html" />


angular.module("directives")
.directive("headermenu", function() {
  return {
    restrict: "EA",
    scope: true,
    templateUrl: function (element, attr) {
      return attr.template;
    },
    link: function(scope, iElement, iAttrs, controller) {
      ....
    }
  };
});

You can pass a function to the templateUrl option and return a string that will be used as a template url at the end.

First of all assign a role onto the element as an attribute (where userRole is bound to scope) as:

<div my-directive user-role="{{userRole}}></div>

Then the directive can read it as:

myApp.directive('myDirective', function() {
  return {
    restrict: 'A',
    templateUrl: function(element, attrs) {
      return "../assets/common/headerMenu" + attrs.userRole + ".html";
    }
  }
});

Update: This used to work before with older version of Angular.

<div ng-if="userRole === 'admin'" my-directive user-role="admin"></div>

Answer 3

you can manipulate ng-include as a template

html:

<headermenu user-role="selectedUserRole"></headermenu>

js:

app.directive('headermenu', function() {
  return {
    restrict: 'E',
    scope: {
      userRole : '='
    },
    link: function($scope)
    {
      $scope.$watch('userRole', function(userRole)
      {
        if (userRole && userRole.length)
        {
            $scope.dynamicTemplateUrl = 'assets/common/headerMenu' + userRole + '.html';
        }
      });
    },

    template: '<ng-include src="dynamicTemplateUrl"></ng-include>'
  };
});

Or if you don't want to set the full path in the controller:

html:

<headermenu path="assets/common/headerMenu{{selectedUserRole}}.html"></headermenu>

js:

app.directive('headermenu', function() {
  return {
    restrict: 'E',
    scope: {
      path : '@'
    },
    template: '<ng-include src="path"></ng-include>'
  };
});

Why not do:

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

then:

$scope.getActualTemplateContent= function() {
  return '../assets/common/headerMenu/' + $scope.user_role + '.html';
};
