如何作爲變量訪問angularJS控制器？

Question

如何將控制器的值定義爲自定義指令鏈接函數內的元素？

HTML

<div ng-controller="myCtrl as ctrl"> 
    <input type="text" ng-model=ctrl.inputvalue" my-directive/> 
    <button value="submit" ng-disabled="ctrl.disable"/> 
</div> 

JS

app.controller('myCtrl',function(){ 
    var vm = this; 
    vm.inputValue = 'Qwerty'; 
}); 
app.directive('myDirective',function(){ 
    return{ 
     require:'ngModel', 
     link:function(scope,elements,ngModelCtrl){ 
     //How to access ng-diasbled value here 
     }); 
    }  
}); 

Answer 1

內部鏈接功能寫爲scope.ctrl.disable訪問禁用值。

Answer 2

app.directive('myDirective',function(){ 
     return{ 
      require:'ngModel, ^myCtrl', 
      link:function(scope,elements,ctrls){ 
       var d = ctrls[1].disable 
      }); 
     }  
    });
