Javascript 在HTML和PHP中显示“正在播放”

我一直在尝试使用一些PHP和HTML代码以及一些js来为我的网站创建一个“正在播放”的spotify查看器。我就是不能让它工作。我已经尝试了所有的可能性，比如重命名文件、更改HTML、PHP和JS版本，但似乎没有任何效果。下面是我的HTML代码js和PHP代码

    <script src="jquery-1.11.0.min.js"></script>
<!--Begin Spotify Scrobble-->
<SCRIPT TYPE="text/javascript">function get_spotify() {
    $.ajax({
        type: 'POST',
        url: '/public_html/Spotify.php',
        data: { request: 'true' },
        success: function(reply) {
            $('.now-playing').html("<p>" + reply + "</p>");
        }
    });
}
</script>
<!--End Spotify Scrobble-->

为什么你不能让它工作？有错误吗？小细节可以帮助我们准确地解决您的问题有一个错误，解析错误：语法错误，在第33行的/home/a1825511/public\u html/Spotify.php中出现意外的TúIF，但这只是刚刚开始出现。之前，它只是给了我一个没有spotify插件Showingallight的标准网页。这不是JS的问题。还可以将您的凭证从post中键入，然后您可以发布spotify.php的代码，而不使用diff文本？
