2、用服务端语言获取到服务器的磁盘信息，把结果输出
3、在本地用JS写一段AJAX脚本，远程请求服务端写好的程序，得到结果，并展示给用户
<html>
<head>
<title>提取硬盘序列号</title>
<script>
function disk() {//硬盘序列号 信息
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
var service = locator.ConnectServer(".");
var properties = service.ExecQuery("SELECT * FROM Win32_DiskDrive");
var e = new Enumerator (properties);
document.write("<table border=1>");
for (;!e.atEnd();e.moveNext ())
{
var p = e.item ();
document.write("<tr>");
document.write("<td>" + p.signature + "</td>");
document.write("</tr>");
}
document.write("</table>");
}
</script>
</head>
<body>
<input type="button" value="硬盘序列号" onclick="disk()">
</body>
</html>
在这上找的代码：
对于写过ASP或.net 的人来说,通过asp或.net 语言来获得客户端的硬件信息是很熟悉的.但如何通过javascript这种客户端脚本来获得客户端的信息呢?请看以下实例:

使用javascript方式获得客户端的信息主要的优点是,不需求服务器资源.不需求刷新网页.直接在客户端执行脚本获得显示.
在这上找到了硬盘序列号的参数：
\'获得硬盘序列号
Dim cmicWmi As New System.Management.ManagementObjectSearcher(\"SELECT * FROM Win32_DiskDrive\")
Dim Uint32 As UInt32
For Each cmicWmiObj As ManagementObject In cmicWmi.Get
Uint32 = cmicWmiObj(\"signature\")
Next
TextBox1.Text = Uint32.ToString
