javascript - 有没有办法从 AngularJS 指令中获取外部 Controller 名称？

Question

我是 AngularJS 的新手...这是问题:

例如:

HTML

<div ng-controller='DemoController'>
  <div my-directive></div>
</div>

JavaScript

app.directive('myDirective', function(){
  return {
    restrict: 'A',
    link: function(scope, element, attrs){
      //I want to get the outer controller name (in this case 'DemoController') here when using this directive
      // var controller_name = ?
    }
  };
});

如何获取外部 Controller 名称？

感谢您的帮助

您可以使用指令的属性将您想要的任何内容传递给指令。请参阅guide about directives 。在你的情况下，可以这样做:

HTML

<div ng-controller='DemoController'>
  <div my-directive="DemoController"></div>
</div>

JS

app.directive('myDirective', function(){
  return {
    restrict: 'A',
    link: function(scope, element, attrs){
      var controller_name = attrs.myDirective;
    }
  };
});
