在指令和控制器中使用ng-model [英] Use ng-model in directive and controller

问题描述

是否可以在Directive中访问链接到Controller的ng-model？

Is it possible to access in Directive the ng-model that is linked to the Controller?

<input type="text" ng-model="ctrl.valuelist.value" />

控制器：

ctrl.valuelist.value = 'initial value';

指令：

function Directive($window) {
  return {
    restrict: 'E',
    scope: {
    },
    controller: 'ctrl as ctrl',
    link: function(scope, elt, attrs){
      // something like this:

      scope.valuelist.value = 'New value';


    }
  };
}

推荐答案

function Directive($window) {
  return {
    restrict: 'E',
    scope: {
      ngModel: '=' //<----- access to the model by this
    },
    controller: 'ctrl as ctrl',
    link: function(scope, elt, attrs){
      // something like this:

      scope.ngModel = 'New value';


    } 
  };
}

我是个傻瓜，所以要善待。
