angularjs – “shahab”指令中的控制器不起作用.(是Null)

导读：我有两个指令,想要访问在hossein指令中定义的控制器. 指示 app.directive('hossein',function() { return { restricted: 'A',require: '?ngModel',scope: { name: '=ngModel' },link: function(scope,element,attributes,ngModel) { console.log(",",scope.n

我有两个指令,想要访问在hossein指令中定义的控制器.

指示

app.directive('hossein',function() {
  return {
    restricted: 'A',require: '?ngModel',scope: {
      name: '=ngModel'
    },link: function(scope,element,attributes,ngModel) {
      console.log(",",scope.name);
    },controller: function($scope) {
      var name = $scope.name;
      this.fu = function() {
        return name;
      }
    }
  }
});
app.directive('shahab',require: '^?hossein',scope: {
      name: '=ngName'

    },controll) {
      console.log(",gfddfdfg,controll);
      scope.name = controll.fu();
    }
  }
});

标记

<div ng-app="app">
    <div ng-controller="maincontroller">
        <form ng-controller="newcontroller" name="myform" id="form">
            <h2>AngularJS</h2>
            <p>Name:
                <input name="user" type="text" hossein ng-model="name">
            </p>
            <p>Family:
                <input name="famil" type="text" shahab ng-name="">
            </p>
        </form>
    </div>
</div>

解决方法

您必须使用嵌套的shahab和hossein指令,以便可以访问外部控制器.

<hossein ng-model="name">

    <shahab ng-name="">

    </shahab>
</hossein>
