Question

包含JSON对象的控制器，然后传递给视图。

'use strict';

//app global variable
//this is the controller that handles post requests
//declare services as dependecies $http, $location, custom service apiServiceWeb
app.controller('menteeMentorsCtrl', function($scope, $http, $cookies, $rootScope, $location, loggedInStatus, setCredentials, apiServiceWeb) {


  //get cookie, and then make api call
  var cookieData = setCredentials.getCookie('globals');

  console.log(cookieData);
  console.log("email " + cookieData.auth.username);
  console.log("userType " + cookieData.auth.userType);
  console.log("token " + cookieData.auth.token);

  var ctr_scope = $scope;
  $scope.users = []; //declare an empty array

  $scope.alert = {};
  $scope.showAlert = false;
  $scope.users = [{
    "activeMentors": [{

查看：

这是我使用ng-repeat的地方。

 <div role="main" class="container theme-showcase">
      <div class="" style="margin-top:90px;">
        <div class="col-lg-8">
            <div class="page-header">
                <h2 id="tables">list items</h2>
            </div>
            <div class="bs-component" ng-controller="menteeMentorsCtrl">
                <div class="alert alert-info" ng-hide=true>
                    <p>Sort key: {{sortKey}}</p>
                    <p>Reverse: {{reverse}}</p>
                    <p>Search String : {{search}}</p>
                </div>
                <form class="form-inline">
                    <div class="form-group">
                        <label >Search</label>
                        <input type="text" ng-model="search" class="form-control" placeholder="Search">
                    </div>
                </form>

<div ng-repeat="test in users.requestedMentors">
 <span>Name : {{ test.firstName }}</span>
 <span>Age : {{ test.lastName }}</span>
</div>


        </div>
      </div>
    </div>

json对象中有两个父对象，当我在users.requestedMentors中测试时，没有返回任何内容，为什么会发生这种情况，谢谢。

Answer 1

你应该使用

<div ng-repeat="test in users[0]['requestedMentors']">
 <span>Name : {{ test.firstName }}</span>
 <span>Age : {{ test.lastName }}</span>
</div>

<强>释

这是因为users本身就是array of objects，你正试图让它的第一个元素进入。

<强>更新

如果objects数组中有多个users，您应该使用ng-repeat

例如：

<div ng-repeat="user in users">
  <div ng-repeat="test in user['requestedMentors']">
     <span>Name : {{ test.firstName }}</span>
     <span>Age : {{ test.lastName }}</span>
  </div>
</div>

Answer 2

在您的情况下，用户是一个数组对象。在访问用户数组中的每个对象之前，需要首先遍历用户对象。你应该有这样的东西。

ng-repeat不迭代json对象
