AngularJS实现根据变量改变动态加载模板的方法

return {    restrict: 'E',    replace: true,    templateUrl: 'app/view/order.html',    link: function (scope, element, attrs) {      scope.Type = attrs.Type;    }};

 <div ng-switch on="item.Type">  <div ng-switch-when="1"><ng-include src="'views/1.html'"></ng-include></div>  <div ng-switch-when="2"><ng-include src="'views/2.html'"></ng-include></div>  <div ng-switch-when="3"><ng-include src="'views/3.html'"></ng-include></div> </div>
