Javascript股票行情: php页面不显示数据
提问于 2012-06-06 14:40:57
我没有收到任何javascript错误，代码只能正确呈现，但仍然无法在页面上显示数据。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">
<div id="marqueecontent">

</html>下面是服务器显示的页面。
我已经用你的建议更新了截图，我也在html中做了更改，以检查child dev正在显示什么。

查看了原始网站，上面写着：
“如果是股票缓存目录的问题，脚本可能会为每个股票条目打印”0.00PHP0.00“。相反，看起来您的↑服务器没有正确解析，而是吐出了PHP代码。这可能与服务器配置错误或页面上其他地方的代码冲突有关。不幸的是，在不了解更多上下文的情况下，我无法提供更多详细信息，例如相关网页的源代码、服务器操作系统、HTTPD和PHP版本，以及它们的配置。”
在主机帮助中查找，发现它必须允许php (如果它是在html内)，必须创建一个.htaccess文件并添加主机公司给我的行，在与他们的支持人员短暂交谈后，问题得到了解决**
