篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了怎样用JS获取客户端的硬件,系统等信息(适相关的知识,希望对你有一定的参考价值。

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”。
参考技术A 出于安全考虑, 不管什么浏览器都会严禁网页内脚本直接与客户端硬件打交道,只能获取与浏览器直接相关的信息。否则的话,全世界的电脑(以及所有智能移动设备如手机)都将不再有隐私可言!
当然,技术上是完全可以实现的,但是需要把浏览器的安全等级设为最低!

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: 

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: 

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:

<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> 
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>
