Question

我对角度很新，无法找到一个解决方案来访问我的角应用程序中的子菜单项。我可以访问顶级菜单项，但是如何获得第二级项目

下面是我目前的代码

HTML

<!DOCTYPE html>
<html>
<head>
  <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js"></script>
  <script src="app.js"></script>
</head>
<body ng-app="list">  
  <div ng-controller="ListCtrl">
    <ul>
        <li ng-repeat="menu in menus" id="{{artist.id}}">
            <a ng-href="{{menu.content}}">{{menu.description}}</a>
            <ul>
                <li ng-href="{{menu.content}}">{{menu.menu}}</li>
            </ul>
        </li>
    </ul>
  </div>
</html>

的javascript

// Code goes here
angular.module('list', []);

function ListCtrl($scope, $http) {
  $http({
    method: 'GET',
    url: 'menu.json'
  }).success(function(data) {
    $scope.menus = data.menus; // response data
    angular.forEach(data.menus, function(menu, index) {

    });
  });
}

Answer 1

添加另一个ng-repeat

 <!DOCTYPE html>
    <html>
    <head>
      <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js"></script>
      <script src="app.js"></script>
    </head>
    <body ng-app="list">  
      <div ng-controller="ListCtrl">
        <ul>
            <li ng-repeat="menu in menus" id="{{artist.id}}">
                <a ng-href="{{menu.content}}">{{menu.description}}</a>
                <ul>
                    <li ng-href="{{submenu.content}}" ng-repeat="submenu in menu.menu">{{submenu.id}}</li>
                </ul>
            </li>
        </ul>
      </div>
    </html>

Answer 2

要访问子项，您可以使用

<ul>
      <li ng-repeat="menu in menus" id="{{artist.id}}">
        <a ng-href="{{menu.content}}">{{menu.description}}</a>
        <ul>
          <li ng-repeat="submenu in menu.menu">
            <a ng-href="{{menu.content}}">{{submenu.description}}</a>
        </ul>
      </li>
</ul>
