我是 AngularJs 的新手，仍在试图弄清楚基础知识是如何工作的……我正在使用 Soundcloud API 为给定用户提取关注者列表。到目前为止，在我的$scope.init函数中，我能够连接到 Soundcloud，对用户进行身份验证并返回用户关注者的 json 列表。然后我将每个跟随者推入一个名为$scope.results的数组中，并通过在控制台中输出它来验证该数组是否已满。但是，当我尝试ng-repeat 在我的main.html视图中使用将每个追随者输出为数组中的列表项时，我什么也没得到......这是我的代码：

main.js

 .controller('MainCtrl', function ($scope, $http) {
    $scope.apiKey = "##########################";
    $scope.results = [];
    $scope.init = function(){
    SC.initialize({
        client_id: $scope.apiKey,
        redirect_uri: "http://localhost:9000/callback.html"
    });
    // initiate auth popup
    SC.connect(function() {
        SC.get('/me', function(me) { 
        alert('Hello, ' + me.username); 
    });

    SC.get('/me/followers', function(followers) {
        //console.log(followers);
        //angular.forEach(followers, function(value, index){
            angular.forEach(followers, function(follower, index){
                $scope.results.push(follower);
            });
            console.log($scope.results);
    });
});

main.html // 这是一个视图

`<div ng-init="init()">`
`<li ng-repeat="follower in results">`
`<div class="row-fluid">`
    `<div class="span3">`
       `<div class="span6">`
        <h3>{{follower.username}}</h3>
        <p>{{follower.description}}</p>
    </div>
</div>
</div>
</li>
</div>

您错过了对 $apply() 的调用，因为您正在角度世界之外工作，因此请尝试在 push 命令下方添加一行，它应该可以工作

 angular.forEach(followers, function(follower, index){
                $scope.results.push(follower);
            });

$scope.$apply()
