Question

如何在运行时更改fb-video的视频网址，让播放器重新加载视频而不刷新页面：

    <div id="fb-root" style="height: auto"></div>
    <script>(function(d, s, id) {
        var js, fjs = d.getElementsByTagName(s)[0];
        if (d.getElementById(id)) return;
        js = d.createElement(s); js.id = id;
        js.src = "https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.4";
        fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));</script>
    <div class="fb-video"
         data-href="https://www.facebook.com/abcxyz/videos/vb.123/123/?type=1"
         data-allowfullscreen="true"></div>

这就是我现在在HTML中加载页面的代码。我现在只想知道是否有可能以某种方式更改数据-href，然后让Facebook嵌入式视频播放器指向新视频。

Answer 1

在更改FB.XFBML.parse()属性的值后调用JavaScript SDK的data-href方法。

以下是一些文档：

http://developers.facebook.com/docs/reference/javascript/FB.XFBML.parse/

我试图创建一个CodePen或JSBin示例，但Facebook的SDK脚本与沙盒iframe没有很好的协作（它尝试更改document.domain，这是不允许的），所以什么都不会加载。不过，这种方法在我目前的项目中对我有用。
