AngularJS ng-repeat not working?
提问by accraze
I'm new to AngularJs and still trying to figure out how the basics work... I'm using the Soundcloud API to pull a list of followers for a given user. So far in my $scope.initfunction I am able to connect to Soundcloud, authenticate a user and return a json list of the user's followers. I then push each follower into an array called $scope.resultsand verify that the array is full by outputting it in the console. However when I try to output each follower as a list item in the array using ng-repeatin my main.htmlview and I get nothing..... here's my code:
我是 AngularJs 的新手，仍然试图弄清楚基本原理是如何工作的……我正在使用 Soundcloud API 来为给定用户拉取关注者列表。到目前为止，在我的$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。然后我将每个关注者推送到一个名为$scope.results的数组中，并通过在控制台中输出它来验证该数组是否已满。但是，当我尝试将每个关注者作为数组中的列表项输出ng-repeat到我的main.html视图中时，我什么也没得到......这是我的代码：
main.js
主文件
.controller('MainCtrl', function ($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// which is a view
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>

You are missing a call to $apply() because you are doing work outside of the angular world so try to add one line below push command and it should work
您错过了对 $apply() 的调用，因为您正在角度世界之外进行工作，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()
