Question

我正在从包含子菜单的JSON文件构建菜单。我正在使用一个名为JQuery.mmenu的插件。当我使用原始HTML创建子菜单时，它可以正常工作:(运行代码查看）

＆＃13;

var app = angular.module('myApp', ['ngRoute'])

.config(['$routeProvider',
  function($routeProvider) {
    //determines redirects go via shortcuts, clicking on the management icon on the main page sends the routeProvider /MG which it then uses to pull the relevant HTML file
    $routeProvider
      .when('/', {
        controller: 'projectController',
        templateUrl: './assets/html/home.html'
      })
      .when('/t1', {
        controller: 'projectController',
        templateUrl: './assets/html/temp1.html'
      })
      .when('/t2', {
        controller: 'projectController',
        templateUrl: './assets/html/temp2.html'
      })
      .when('/t3', {
        controller: 'projectController',
        templateUrl: './assets/html/temp3.html'
      })

    .otherwise({
      controller: 'projectController',
      templateUrl: './assets/html/home.html'
    })
  }
]);

app.controller('projectController', function projectController($scope, $http, $rootScope, $timeout) {
  $scope.projectInfo = [];
  $scope.menuInfo = [];
  $http.get('config/Config.json').then(function(response) {
    $scope.projectInfo = response.data[0].config;
    $scope.menuInfo = response.data[1].menu;
  });

  // $scope.activeID = 'HM';
  // $scope.activePath = "Assets/images/allActive.png";

  // function getImgPath(item) {
  //     $scope.activePath = "Assets/images/" + item.path + "";
  //     console.log($scope.activePath);
  // }


  $scope.setImgPath = function(btnPath) {
    console.log(btnPath)
    $scope.activePath = "Assets/images/" + btnPath + "";
    console.log($scope.activePath);
  };
  $scope.contentCtrl = function(id) {
    $scope.activeID = id;
    console.log($scope.activeID);
    // $scope.activeItem = item;
    // getImgPath($scope.activeItem);


  };


});

这正是我希望它看起来的样子，但现在当我尝试使用完全相同的结构但是使用ng-repeat从我的json文件中提取时，我得到了这个：

＆＃13;

<nav id="menu">
                <ul>
                    <li ng-repeat="item in menuInfo"> <a class="menuBtn" ng-href="#/{{item.id}}" href ng-click="contentCtrl(item.id)">{{item.name}}</a >
                        <ul>
                            <li><a class="menuBtn" href="/about/history">History</a></li>
                            <li><a class="menuBtn" href="/about/team">The team</a></li>
                            <li><a class="menuBtn" href="/about/address">Our address</a></li>
                        </ul>
                    </li>
                </ul>
            </nav>

＆＃13;

产生这个（到达此处的步骤相同）：

并且无法折叠这些菜单。现在我能看到的唯一区别就是ng重复，当我把它拿出来时，一切似乎都很好。我为什么会发生这种情况感到很沮丧。任何帮助将不胜感激。

最有可能的问题是初始化脚本在$(document).ready()中，但在角度页面中这是相当没价值的，因为角度会在发生之后构建大部分dom。

您需要创建一个指令来初始化插件。如果插件依赖于所有存在的项目，还需要在初始化之前在ng-repeat内指令中监听$last

在网络搜索中，很难找到在指令中初始化jQuery插件的基础知识。如果遇到更多麻烦，可以随时在这里提问
