javascript - 使用 soundloud API 从用户源获取所有轨道

Question

目前，我正在尝试使用 javascript soundcloud API 包装器从用户源中获取所有声音，如下所示:

$('head').append("<script src='https://connect.soundcloud.com/sdk/sdk-3.0.0.js'>");

SC.initialize({
    client_id: 'YOUR_CLIENT_ID',
    redirect_uri: '/callback.html'
});

// initiate auth popup
SC.connect(function() {
    SC.get('/me', function(me) {
        alert('Hello, ' + me.username);
    });
});

var dashTracks = SC.get('/me/activities/tracks/affiliated');

但是当我查看控制台时，出现错误

Uncaught ReferenceError: SC is not defined

我不太确定如何解决它。

Answer 1

在执行代码之前等待脚本加载。

var s = document.createElement('script');
s.type = 'text/javascript';
s.src = 'https://connect.soundcloud.com/sdk/sdk-3.0.0.js';
$('head').append(s);

s.onload = init;

function init() {
    SC.initialize({
        client_id: 'YOUR_CLIENT_ID',
        redirect_uri: '/callback.html'
    });

    SC.connect(function () {
        SC.get('/me', function (me) {
            alert('Hello, ' + me.username);
        });
    });

    var dashTracks = SC.get('/me/activities/tracks/affiliated');
}
