javascript - 如何在 Angular js中相互绑定(bind)两个不同数组的值

Question

嗨，我将使用 Angular js 和 json 来管理用户访问级别。我有两个数组，一个用于菜单结构，另一个用于访问级别。

current access levels :

    $scope.current_access_levels ={
      "can_home":{"title":"home","value":true},
      "can_mail":{"title":"mail","value":false}
    };

menu structure :

    $scope.menu = [
      {"id":"1","name":"home","aclvl":"can_home"},
      {"id":"2","name":"mail","aclvl":"can_mail"}
    ];

每个菜单字段都有一个“aclvl”，与“current_access_level”数组中的对象名称相匹配。

what i'm going to do is something like this :

<div ng-app="app" ng-controller="appCtrl">
      <div  ng-repeat="aclvl in current_access_levels">
        <label>{{aclvl.title}}</label><input type="checkbox" value="1" ng-model="aclvl.value"/>
      </div>
      <br />
      <br />
      <ul>
        <li ng-repeat="men in menu">
          <input type="checkbox" ng-model="current_access_levels.(men.aclvl).value"/>{{men.aclvl}}
        </li>
      </ul>
   </div>

例如，如果“men”的“aclvl”等于“can_home”，则复选框值应等于“aclvl.can_home.value”。任何人都知道我应该如何处理这个问题!？我添加了一个 fiddle 来明确我应该做什么。谢谢

angular.module('app',[])
  .controller('appCtrl',function($scope){
  
    $scope.current_access_levels ={"can_home":{"title":"home","value":true},"can_mail":{"title":"mail","value":false}};

    $scope.menu = [{"id":"1","name":"home","aclvl":"can_home"},{"id":"2","name":"mail","aclvl":"can_mail"}];
  
  });

<div ng-app="app" ng-controller="appCtrl">
  <!-- current access levels -->
  <p>current access levels</p>
  <div  ng-repeat="aclvl in current_access_levels">
    <label>{{aclvl.title}}</label><input type="checkbox" value="1" ng-model="aclvl.value"/>
  </div>
  <!-- current access levels -->
  <br />
    <div>{{current_access_levels}}</div>
  <br />
  <hr>
  <!-- menu structure just for example -->
  <p>menu structure</p>
  <ul>
    <li ng-repeat="men in menu">
      <input type="checkbox" ng-model="current_access_levels.can_home.value"/>{{men.aclvl}}
    </li>
  </ul>
  <!-- menu structure just for example -->
  
</div>

您可以将 [] 与 current_access_levels 一起使用，就像 -

 <li ng-repeat="men in menu">
      <input type="checkbox" ng-model="current_access_levels[men.aclvl].value"/>{{men.aclvl}}
    </li>
