我没有收到任何 javascript 错误,代码只能正确呈现,但服务器仍然没有在页面上显示数据。请检查下面的代码。

 <style type="text/css">
#marqueeborder {
    color: #cccccc;
    background-color: #EEF3E2;
    font-family:"Lucida Console", Monaco, monospace;
    position:relative;
    height:20px; 
    overflow:hidden;
    font-size: 0.7em;
}
#marqueecontent {
    position:absolute;
    left:0px;
    line-height:20px;
    white-space:nowrap;
}
.stockbox {
    margin:0 10px;
}
.stockbox a {
    color: #cccccc;
    text-decoration : underline;
}
</style>

 </head>

 <body>
  <div id="marqueeborder" onmouseover="pxptick=0" onmouseout="pxptick=scrollspeed">

1)首先移动</body>你的javascript之后。
2)你的父母div(id marqueeborder)的高度为20px并且溢出隐藏,所以cild div(id marqueecontent)将被切割,将你的html更改为:

<div id="marqueeborder" onmouseover="pxptick=0" onmouseout="pxptick=scrollspeed"></div>
<div id="marqueecontent">
...
</div>

并将 #marqueecontent 的 css 替换position:absolute; left:0px;position: relative;.

我希望这有帮助...

=== 更新 ===

我的示例中,您只需将 javascript 移动到<head>. html不需要更改!

查看它说的原始网站:

“如果 stockcache 目录有问题,脚本可能会为每个股票条目打印“0.00↑0.00”。相反,它看起来好像您的 HTTP 服务器正在吐出 PHP 代码而不是正确解析它。这可能是与页面上其他地方的服务器错误配置或冲突代码有关。不幸的是,如果不了解更多上下文,我无法更具体,例如相关网页的源代码、服务器操作系统、HTTPD 和 PHP 版本,及其配置。”

在托管帮助中查找,发现它必须允许 php(如果它在 html 中),必须创建一个 .htaccess 文件并添加托管公司给我的行,在与他们的支持问题进行简短交谈后已解决**
