Angularjs 虽然 controller/factory 有数据，但视图是空的/没有从 $scope 中提取数据

Question

我是 Ionic & Angular 的新手，正在按照教程示例学习它 here

在运行代码中，控制器和工厂似乎正在正确获取数据，但项目是空的。我该如何解决？

HTML:

<ion-header-bar class="bar-stable">
    <h1 class="title">Page 2!</h1>
</ion-header-bar>
<ion-content class="padding">
    <p>Going to add playlist and video player here</p>
    <ion-list>
            <ion-item class="item-avatar" ng-repeat="item in users">
                <!--changed to ng-src to fix string problem-->
                <img ng-src="{{item.user.picture.thumbnail}}"/>
                <h2>{{item.user.name.first}} {{item.user.name.last}}</h2>
                <p>{{item.user.location.city}} {{item.user.password}}</p>
            </ion-item>
    </ion-list>
</ion-content>

控制器

已添加 $scope.users=[]；根据 here

angular.module('starter.controllers', ['ionic','starter.services'])

.controller('MainCtrl',function(){
  console.log("Main Controller says: Hello World");
})

.controller('PlaylistCtrl',function($scope, userService){
    $scope.users=[];
    userService.getPlaylist().then(function(users){
        $scope.users = users;
        console.log($scope.users);
    });
})

服务

angular.module('starter.services', ['ionic'])

.factory('userService', function($http) {
    return {
        getPlaylist: function(){
            return $http.get('https://randomuser.me/api/?results=10').then(function(response){
                return response.data.results;
            });
        }
    }

})

您好，根据图片，您的值直接在项目内，但在您的 HTML 中，您提到了

 <img ng-src="{{item.user.picture.thumbnail}}"/>

这是错误的，你的数组中没有用户对象，所以必须像这样直接调用键

<img ng-src="{{item.picture.thumbnail}}"/>

改变你的HTML

<ion-item class="item-avatar" ng-repeat="item in users">
                <!--changed to ng-src to fix string problem-->
                <img ng-src="{{item.picture.thumbnail}}"/>
                <h2>{{item.name.first}} {{item.name.last}}</h2>
                <p>{{item.location.city}} {{item.password}}</p>
            </ion-item>

Angularjs 虽然 controller/factory 有数据，但视图是空的/没有从 $scope 中提取数据

Angularjs view empty/ not pulling data from $scope though controller/factory have the data

angularjs-scope

angularjs-factory
