JavaScript獲取客戶端計算機硬件及系統等信息的方法

JavaScript 獲取客戶端計算機硬件及系統信息

通過WMI來實現獲取客戶端計算機硬件及系統信息:

複製代碼代碼如下:

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;

//內存信息

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}

//系統信息

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}

}

代碼實現主要包括這幾部分：

先通過new ActiveXObject ("WbemScripting.SWbemLocator"); 訪問到WbemScripting對象。

通過locator.ConnectServer(".");連接我們本地電腦（.代表本地電腦，當然

也可以訪問其他計算機）。

通過service.ExecQuery("SELECT * FROM Win32_Processor")這個類似sql的語句（其實係統信息也是存儲在計算中一個類似數據庫的文件中）獲取我們需要的對象的記錄集。

通過new Enumerator來創建一個可枚舉的對象，下面就可以遍歷取信息了。

注意：運行的前提是要修改瀏覽器安全設置，“允許對未標記為可安全執行的ActiveX

腳本的運行”。

這裡主要取了CPU、內存及系統用戶幾個信息，大家利用WMI的API或者藉助JSEDIT獲取

到更多的信息。下面列出了常用信息的類：

Win32_Processor // CPU 處理器

Win32_PhysicalMemory // 物理內存

示例：

複製代碼代碼如下:

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() {//鍵盤信息

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，通過以下方式也可以獲得系統的相關信息：

複製代碼代碼如下:

<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>

複製代碼代碼如下:

其實最關鍵的還是用到兩個ActiveX：

<OBJECT id=locator classid=CLSID:76A64158-CB41-11D1-8B02-00600806D9B6 VIEWASTEXT></OBJECT>

<OBJECT id=foo classid=CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223></OBJECT>

不過這兩個ActiveX都是系統自帶，不用去下載或註冊。

接下來的工作就是用腳本和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>
