Soundcloud API 中的错误:无法读取 null 的 属性 'substr'

Error in the Soundcloud API: Cannot read property 'substr' of null

我正在尝试使用 Soundcloud API(本地)编写 Widget。

这是我的代码:

<!DOCTYPE html>
<html>
<head>
<title>Soundcloud musics</title>
</head>
<body>
<h1>Soundcloud musics</h1>
<iframe id="iframe"
    class="iframe"
    width="100%"
    height="465"
    scrolling="no"
    frameborder="no">
</iframe>
<script src="api.js"></script>
<script>
    var player;
    player = SC.Widget(document.getElementById('iframe'));
    console.debug(player);
    player.load('https://soundcloud.com/somesong', null);
</script>
</body>
</html>

我从 运行 得到的错误是:

Uncaught TypeError: Cannot read property 'substr' of null
E @ api.js:204
d @ api.js:328
n.exports.v @ api.js:326
(anonymous function) @ index.html:21

我已将 soundcloud 的最小化 api 代码输入到 js 美化器中,以便我可以跟踪错误。这是代码:https://jsfiddle.net/0anL7jfs/

我做错了什么吗?看来问题出在 SC.Widget() 函数...

您需要更改一些内容:

Define src within your iframe with the player widget api url and properties:

<iframe id="iframe"
     class="iframe"
     width="100%"
     height="465"
     scrolling="no"
     frameborder="no"
     src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/76067623&amp;auto_play=false&amp;hide_related=true&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false&amp;visual=true">
</iframe>

Bind your events with widget.bind:

<script type="text/javascript">
(function(){
    var iframeElement = document.getElementById('iframe');
    var widget = SC.Widget(iframeElement);
    widget.bind(SC.Widget.Events.READY, function () {
        console.log('Ready');
        widget.bind(SC.Widget.Events.PLAY, function () {
            widget.getCurrentSound(function (sound) {
                console.log(sound.title);
            });
        });
           widget.bind(SC.Widget.Events.FINISH, function () {
               console.log('Finished');
        });
    });
}());
</script>
