javascript - 我如何通过 angularJS 中的嵌套键值对正确地重复 ng-repeat

Question

Angular JS

究竟如何才能正确地遍历嵌套的键值对并像下面这样正确地输出它们？

我想要的 View 是这样一棵树

-touts
  -classes
    -col-12 
    -col-md-12
    -col-lg-12

当前 View 是:

touts
  {"classes":["col-12","col-md-12","col-lg-12"]}

JS:

var currentApp = angular.module('currentApp', []);
currentApp.controller('ACtrl', function($scope){

    $scope.templates = {
        'touts' : [
            {
                'classes' : ['col-12', 'col-md-12', 'col-lg-12' ]
            }
        ]
    };
});

HTML:

<div ng-app="currentApp">
    <div ng-controller="ACtrl">
        <ul ng-repeat="(key, prop) in templates">
            <li>{{key}}</li>
              <li>
                  <ul ng-repeat="class in templates[key]">
                      <li>{{class}}</li>
                  </ul>
            </li>
        </ul>
    </div>
</div>

你非常接近，我更新了 fiddle 。 http://jsfiddle.net/y9wj6/9/

   <ul ng-repeat="(key, prop) in templates">
        <li>{{key}}</li>
        <ul ng-repeat="val in prop">
            <ul ng-repeat="(o, values) in val">
            <li>{{o}}</li>
                 <ul ng-repeat="i in values">
                      <li>{{i}}</li>
                  </ul
             </ul>
        </ul>
    </ul>
