慢速页面加载在WordPress的侧边栏

问题描述：

所以基本上，我不知道有关PHP，但不知何故，我设法让这个脚本工作。
（该脚本检查是否是直播，在线[上www.own3d.tv]，如果是在网上，它显示的拖缆与观众的名称。如果是离线的，它什么也不显示。）

我插它到我的WordPress的siderbar。但事实是，当我打开我的页面时，所有其他内容都会加载，但侧边栏需要几秒钟才能加载。我想这需要很长时间来检查直播。
那么，有没有办法让它加载更快，或让它加载边栏上的其他东西？

在此先感谢您的答复。

看起来LiveCheck API非常慢。您可能想要使用AJAX加载查看器计数编号。这样你就可以立即填写静态信息。如果你在你的文件的头部安装了jQuery，一个简单的脚本标签将包含以下内容。我会在下面的答案中添加一个片段。 – 2012-04-05 23:29:05

谢谢你的回复。我试过了这个代码，但它被卡在“Loading ...”中。它不会显示观看者。 – user1316468 2012-04-06 00:34:21

尝试建立在你的侧边栏一个简单的文本组件粘贴到内容这一点。只要确保您的主题已安装jQuery：

Froggen - Viewers: <a class="live-viewers" href="http://www.own3d.tv/live/112348/">Loading...</a> 

<script type='text/javascript'> 
$(document).ready(function() { 
    $.get("http://api.own3d.tv/liveCheck.php?live_id=112348", function (res) { 
    var xml = $.parseXML(res); 
    $('.live-viewers').text(res.own3dReply.liveEvent.liveViewers[0]; 
}); 
</script>

谢谢你的回复。我试过了这个代码，但它被卡在“Loading ...”中。它不会显示观众 – user1316468 2012-04-06 01:08:56

答

您应该缓存这些simplexml_load_file（）调用的结果。第一次调用将花费正常的时间，但随后的调用将加载缓存的数据并执行得非常快。

我很抱歉问这个问题，但我该怎么做？正如我所说，我不知道任何关于PHP。对不起，请帮助我 – user1316468 2012-04-06 01:54:55
