JavaScript获取客户端计算机硬件及系统等信息的方法

JavaScript 获取客户端计算机硬件及系统信息
通过WMI来实现获取客户端计算机硬件及系统信息:

复制代码 代码如下:

function getSysInfo(){
var locator = new ActiveXObject (\"WbemScripting.SWbemLocator\");
var service = locator.ConnectServer(\".\");
//CPU信息
var cpu = new Enumerator (service.ExecQuery(\"SELECT * FROM Win32_Processor\")).item();
var cpuType=cpu.Name,hostName=cpu.SystemName;
//内存信息
var memory = new Enumerator (service.ExecQuery(\"SELECT * FROM Win32_PhysicalMemory\"));
for (var mem=[],i=0;!memory.atEnd();memory.moveNext()) mem[i++]={cap:memory.item().Capacity/1024/1024,speed:memory.item().Speed}
//系统信息
var system=new Enumerator (service.ExecQuery(\"SELECT * FROM Win32_ComputerSystem\")).item();
var physicMenCap=Math.ceil(system.TotalPhysicalMemory/1024/1024),curUser=system.UserName,cpuCount=system.NumberOfProcessors

return {cpuType:cpuType,cpuCount:cpuCount,hostName:hostName,curUser:curUser,memCap:physicMenCap,mem:mem}
}

代码实现主要包括这几部分：

先通过new ActiveXObject (\"WbemScripting.SWbemLocator\"); 访问到WbemScripting对象。
通过locator.ConnectServer(\".\");连接我们本地电脑（.代表本地电脑，当然
也可以访问其他计算机）。
通过service.ExecQuery(\"SELECT * FROM Win32_Processor\")这个类似sql的语句（其实系统信息也是存储在计算中一个类似数据库的文件中）获取我们需要的对象的记录集。
通过new Enumerator来创建一个可枚举的对象，下面就可以遍历取信息了。

注意：运行的前提是要修改浏览器安全设置，“允许对未标记为可安全执行的ActiveX
脚本的运行”。
这里主要取了CPU、内存及系统用户几个信息，大家利用WMI的API或者借助JSEDIT获取
到更多的信息。下面列出了常用信息的类：

示例：
复制代码 代码如下:

function button1_onclick() {//cpu 信息
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>\");
}

function Button2_onclick() {//CD-ROM 信息
var locator = new ActiveXObject (\"WbemScripting.SWbemLocator\");
var service = locator.ConnectServer(\".\");
var properties = service.ExecQuery(\"SELECT * FROM Win32_CDROMDrive\");
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.Description + \"</td>\");
document.write(\"<td>\" + p.Drive + \"</td>\");
document.write(\"<td>\" + p.Status + \"</td>\");
document.write(\"<td>\" + p.MediaLoaded + \"</td>\");
document.write(\"</tr>\");
}
document.write(\"</table>\");
}

function Button3_onclick() {//键盘信息
var locator = new ActiveXObject (\"WbemScripting.SWbemLocator\");
var service = locator.ConnectServer(\".\");
var properties = service.ExecQuery(\"SELECT * FROM Win32_Keyboard\");
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.Name + \"</td>\");
document.write(\"<td>\" + p.Status + \"</td>\");
document.write(\"</tr>\");
}
document.write(\"</table>\");
}

function Button4_onclick() {//主板信息
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>\");
}


另外，通过以下方式也可以获得系统的相关信息：
复制代码 代码如下:

<HTML><HEAD><TITLE>WMI Scripting HTML</TITLE>
<META http-equiv=Content-Type content=\"text/html; charset=gb2312\">
<SCRIPT language=JScript event=\"OnCompleted(hResult,pErrorObject, pAsyncContext)\" for=foo>
document.forms[0].txtMACAddr.value=unescape(MACAddr);
document.forms[0].txtIPAddr.value=unescape(IPAddr);
document.forms[0].txtDNSName.value=unescape(sDNSName);
//document.formbar.submit();
</SCRIPT>

<SCRIPT language=JScript event=OnObjectReady(objObject,objAsyncContext) for=foo>
if(objObject.IPEnabled != null && objObject.IPEnabled != \"undefined\" && objObject.IPEnabled == true)
{
if(objObject.MACAddress != null && objObject.MACAddress != \"undefined\")
MACAddr = objObject.MACAddress;
if(objObject.IPEnabled && objObject.IPAddress(0) != null && objObject.IPAddress(0) != \"undefined\")
IPAddr = objObject.IPAddress(0);
if(objObject.DNSHostName != null && objObject.DNSHostName != \"undefined\")
sDNSName = objObject.DNSHostName;
}
</SCRIPT>

<META content=\"MSHTML 6.00.2800.1106\" name=GENERATOR></HEAD>
<BODY>
<OBJECT id=locator classid=CLSID:76A64158-CB41-11D1-8B02-00600806D9B6 VIEWASTEXT></OBJECT>
<OBJECT id=foo classid=CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223></OBJECT>
<SCRIPT language=JScript>
var service = locator.ConnectServer();
var MACAddr ;
var IPAddr ;
var DomainAddr;
var sDNSName;
service.Security_.ImpersonationLevel=3;
service.InstancesOfAsync(foo, \'Win32_NetworkAdapterConfiguration\');
</SCRIPT>

<FORM id=\"formfoo\" name=\"formbar\" action=\"index.do\" method=\"post\"><INPUT value=\"00-11-11-B4-52-EF\" name=\"txtMACAddr\"> <INPUT value=\"210.42.38.50\" name=\"txtIPAddr\"> <INPUT value=\"zhupan\" name=\"txtDNSName\"> </FORM></BODY></HTML>

复制代码 代码如下:

其实最关键的还是用到两个ActiveX：
<OBJECT id=locator classid=CLSID:76A64158-CB41-11D1-8B02-00600806D9B6 VIEWASTEXT></OBJECT>
<OBJECT id=foo classid=CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223></OBJECT>
不过这两个ActiveX都是系统自带，不用去下载或注册。
接下来的工作就是用脚本和ActiveX交互

<HTML>
<head>
<script language=\"javascript\" type=\"text/javascript\">
function getCode(){
var locator = new ActiveXObject(\"WbemScripting.SWbemLocator\");
var service = locator.ConnectServer(\".\");
var properties = service.ExecQuery(\"SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled=TRUE\");
var e = new Enumerator(properties);
document.write(\"<table border=1>\");
for (; !e.atEnd(); e.moveNext()) {
var p = e.item();
//if(p.IPAddress(0)!=null && p.IPAddress(0)!=\"undefined\" && p.IPAddress(0)!=\"0.0.0.0\" && p.IPAddress(0)!=\"127.0.0.1\"){
document.write(\"<tr>\");
document.write(\"<td>\" + p.ServiceName + \"</td>\");
document.write(\"<td>\" + p.MACAddress + \"</td>\");
document.write(\"<td>\" + p.IPAddress(0) + \"</td>\");
document.write(\"</tr>\");
//break;
//}
}
document.write(\"</table>\");
}
</script>
</head>
<BODY>
<button id=\"TEST\" value=\"test\" onclick=\"getCode()\">TEST</button>
</BODY>
</HTML>
