Question

我正在使用Ionic构建我的第一个混合应用程序，有一些我不明白的东西。离子导航视图的用途是什么。

我解释说：我有一个带有＆＃34; nav-tabs＆＃34;的应用程序。以下是导航标签的代码：

<ion-tab title="Contacts" icon="icon-users" href="#/tab/contacts">
    <ion-nav-view name="tab-contacts"></ion-nav-view>
</ion-tab>

这里一切都好。现在，我的联系人列表是一个如下所示的列表：

<ion-item href="#/tab/contacts/{{contact.id}}" ng-repeat="contact in contacts | orderBy:'name'">
    {{contact.name}}
</ion-item>

以下是我的问题：我为＆＃39; / tab / contacts /：id＆＃39;和视图配置了路线。问题是：我应该在哪里放置＆＃34; ion-nav-view＆＃34;指令，以便在我点击时实际显示我的视图？

谢谢！

我认为最好的答案是一个类似于你想要做的工作实例。

但是<ion-nav-view>必须位于index.html中，路由/状态管理器将放置您的视图模板。模板有另一个指令<ion-view>，它包含视图的所有其他指令和内容。

检查以下代码段：

angular.module('ionicApp', ['ionic'])

.config(function($stateProvider, $urlRouterProvider) {

  $stateProvider
    .state('tabs', {
      url: '/tab',
      abstract: true,
      templateUrl: 'views/tabs.html'
    })
    .state('tabs.contacts', {
      url: '/contacts',
      views: {
        'tab-contacts': {
          templateUrl: 'views/contacts.html',
          controller: 'contactsCtrl',
          resolve: {
            allcontacts: function(Contacts) {
              console.log("resolve allcontacts");
              return Contacts.all();
            }
          }
        }
      }
    })
    .state('tabs.detail', {
      url: '/detail/:id',
      views: {
        'tab-detail': {
          templateUrl: 'views/detail.html',
          controller: 'detailCtrl',
          resolve: {
            contact: function($stateParams, Contacts) {
              return Contacts.get($stateParams.id);
            }
          }
        }
      }
    });

  $urlRouterProvider.otherwise("/tab/contacts");

})

.controller('contactsCtrl', function($scope, $ionicLoading, $ionicPopover, $ionicPopup, $compile, $http, allcontacts) {
  console.log("contactsCtrl");
  $scope.contacts = allcontacts;
})

.controller('detailCtrl', function($scope, contact, $ionicHistory) {
  $scope.contact = contact;
  console.log("detailCtrl", contact);
  $scope.myGoBack = function() {
      $ionicHistory.goBack();
  };
})

.factory('Gravatar', function() {
  return {
    getUrl: function(s){ 
      return "https://secure.gravatar.com/avatar/"+CryptoJS.MD5(""+Math.random())+"?d=identicon&s="+s;
    }
  }
})

.factory('Contacts', function($http, $q, $timeout, Gravatar) {
  var contacts = [];
  return {
    all: function(){
      var dfd = $q.defer();
      //$http.get('../data/contacts.json').then(function(response){
      $timeout(function() {
        //contacts = response.data;
        contacts = [{
