Question

我正在开发移动应用。我想创建一个嵌套列表。谁能帮我吗。对于例如在我的第一页列表是：食品，饮料。点击食物我想显示L1，L2，L3等。

我怎样才能做到这一点？

Answer 1

不确定这是否是推荐方式，但这对我有用

        <ion-list>
            <ion-item nav-clear menu-close ng-click="toggleSubmenu()">Menu 1</ion-item>
            <ion-item nav-clear menu-close ng-show="submenu">
                <ion-list>
                    <ion-item nav-clear menu-close>Submenu 1</ion-item>
                    <ion-item nav-clear menu-close>Submenu 2</ion-item>
                    <ion-item nav-clear menu-close>Submenu 3</ion-item>
                </ion-list>
            </ion-item>
            <ion-item nav-clear menu-close>Menu 2</ion-item>
            <ion-item nav-clear menu-close>Menu 3</ion-item>
            <ion-item nav-clear menu-close>Menu 4</ion-item>
        </ion-list>

您可以使用ionic-starter-tabs来说明您所描述的导航。这是来自同一来源的运行示例：http://plnkr.co/edit/qYMCrt?p=preview

此行为是由ui-router已包含的Ionic实现的：

 .state('tab.friend-detail', {
  url: '/friend/:friendId',
  views: {
    'tab-friends': {
      templateUrl: 'friend-detail.html',
      controller: 'FriendDetailCtrl'
    }
  }
})

希望这将有效

HTML代码

<ion-item  ng-click="showSubMenu()">
    Show Submenu            
    <div ng-if="isShowSubMenu">
        <ion-item menu-close  href="#/app/one">
            Submenu Menu One
        </ion-item>
        <ion-item menu-close href="#/app/two">
            Submenu Menu Two
        </ion-item>
        <ion-item menu-close href="#/app/three">
            Submenu Menu Three
        </ion-item>
    </div>
</ion-item>

在 Controller.Js 文件

中记下控制器中的以下功能

 $scope.showSubMenu = function(){
      $scope.isShowSubMenu=!$scope.isShowSubMenu;
  };

在 app.js

中记下以下代码

.config(function($stateProvider, $urlRouterProvider) {
  $stateProvider
    //// ===========  New Start
    .state('app.one', {
        url: '/one',
        views: {
            'menuContent': {
                templateUrl: 'templates/1Menu.html',
                controller: 'FirstCtrl'
            }
        }
    })
    .state('app.two', {
        url: '/two',
        views: {
            'menuContent': {
                templateUrl: 'templates/2Menu.html',
                controller: 'SecondCtrl'
            }
        }
    })

    .state('app.three', {
        url: '/three',
        views: {
            'menuContent': {
                templateUrl: 'templates/3Menu.html',
                controller: 'ThirdCtrl'
            }
        }
    })
});

在controller.js档案

中创建控制器

.controller('FirstCtrl', function($scope){
    $scope.pageLable='One';
})

.controller('SecondCtrl', function($scope){
    $scope.pageLable='Two';
})

.controller('ThirdCtrl', function($scope){
    $scope.pageLable='Three';
})

HTML页面1Menu.html

<ion-view view-title="One">
  <ion-content>
    <h1>{{pageLable}}</h1>
  </ion-content>
</ion-view>

我不知道是谁创造了这个代码，但解决你的问题真的很棒。

angular.module('ionicApp', ['ionic'])

.controller('MyCtrl', function($scope) {
  $scope.groups = [];
  for (var i=0; i<10; i++) {
    $scope.groups[i] = {
      name: i,
      items: [],
      show: false
    };
    for (var j=0; j<3; j++) {
      $scope.groups[i].items.push(i + '-' + j);
    }
  }
  
  /*
   * if given group is the selected group, deselect it
   * else, select the given group
   */
  $scope.toggleGroup = function(group) {
    group.show = !group.show;
  };
  $scope.isGroupShown = function(group) {
    return group.show;
  };
  
});

.list .item.item-accordion {
  line-height: 38px;
  padding-top: 0;
  padding-bottom: 0;
  transition: 0.09s all linear;
}
.list .item.item-accordion.ng-hide {
  line-height: 0px;
}
.list .item.item-accordion.ng-hide-add,
.list .item.item-accordion.ng-hide-remove {
  display: block !important;
}

            &nbsp;
            Group {{group.name}}
          </ion-item>
          <ion-item class="item-accordion"
                    ng-repeat="item in group.items"
                    ng-show="isGroupShown(group)">
            {{item}}
          </ion-item>
        </div>
      </ion-list>

    </ion-content>
