使用javascript获取硬件信息
1.获取硬件列表

<meta name="GENERATOR" content="Microsoft Visual Studio .NET
7.1">
<meta name="vs_targetSchema"

<script id=clientEventHandlersJS language=javascript>
<!--
function Button1_onclick() {
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
var service = locator.ConnectServer(".");
var properties = service.ExecQuery("SELECT * FROM
Win32_OnBoardDevice");
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.Description + "</td>");
document.write("<td>" + p.DeviceType + "</td>");
document.write("<td>" + p.Enabled + "</td>");
document.write("<td>" + p.Tag + "</td>");
document.write("</tr>");
}
document.write("</table>");
}
//-->
</script>
</head>
<body>
<INPUT id="Button1" type="button" value="Button"
name="Button1" language=javascript onclick="return Button1_onclick()">
</body>
</html>
2.Javascript获取CPU信息

<head>
<title></title>
<meta name="GENERATOR" content="Microsoft Visual Studio .NET
7.1">
<meta name="vs_targetSchema"

<script id=clientEventHandlersJS language=javascript>
<!--
function Button1_onclick() {
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
var service = locator.ConnectServer(".");
var properties = service.ExecQuery("SELECT * FROM Win32_Processor");
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.Caption + "</td>");
document.write("<td>" + p.DeviceID + "</td>");
document.write("<td>" + p.Name + "</td>");
document.write("<td>" + p.CpuStatus + "</td>");
document.write("<td>" + p.Availability + "</td>");
document.write("<td>" + p.Level + "</td>");
document.write("<td>" + p.ProcessorID + "</td>");
document.write("<td>" + p.SystemName + "</td>");
document.write("<td>" + p.ProcessorType + "</td>");
document.write("</tr>");
}
document.write("</table>");
}
//-->
</script>
</head>
<body>
<INPUT id="Button1" type="button" value="Button"
name="Button1" language=javascript onclick="return Button1_onclick()">
</body>
</html>
3.Javascript获取主板信息
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title></title>
<meta name="GENERATOR" content="Microsoft Visual Studio .NET
7.1">
<meta name="vs_targetSchema"
content="http://schemas.microsoft.com/intellisense/ie5">
<script id=clientEventHandlersJS language=javascript>
<!--
function Button1_onclick() {
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
var service = locator.ConnectServer(".");
var properties = service.ExecQuery("SELECT * FROM Win32_BaseBoard");
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.HostingBoard + "</td>");
document.write("<td>" + p.Manufacturer + "</td>");
document.write("<td>" + p.PoweredOn + "</td>");
document.write("<td>" + p.Product + "</td>");
document.write("<td>" + p.SerialNumber + "</td>");
document.write("<td>" + p.Version + "</td>");
document.write("</tr>");
}
document.write("</table>");
}
//-->
</script>
</head>
<body>
<INPUT id="Button1" type="button" value="Button"
name="Button1" language=javascript onclick="return Button1_onclick()">
</body>
</html>
在做测试时，会弹出时候允许ActiveX交互，选择允许。而在服务器上运行时可能会出现“Automation 服务器不能创建对象”的javascript错误。出现此错误时，在工具-->Internet选项-->安全-->自定义级别-->启用"对没有标记为安全的ActiveX控件进行初始化和脚本运行",即可解决此问题。
