JavaScript擷取用戶端電腦硬體及系統等資訊的方法_javascript技巧

JavaScript 擷取用戶端電腦硬體及系統資訊
通過WMI來實現擷取用戶端電腦硬體及系統資訊:

複製代碼 代碼如下:

function getSysInfo(){
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
var service = locator.ConnectServer(".");
//CPU資訊
var cpu = new Enumerator (service.ExecQuery("SELECT * FROM Win32_Processor")).item();
var cpuType=cpu.Name,hostName=cpu.SystemName;
//記憶體資訊
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}
//系統資訊
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(".");串連我們本地電腦（.代表本地電腦，當然
也可以訪問其他電腦）。
通過service.ExecQuery("SELECT * FROM Win32_Processor")這個類似sql的語句（其實系統資訊也是儲存在計算中一個類似資料庫的檔案中）擷取我們需要的對象的記錄集。
通過new Enumerator來建立一個可枚舉的對象，下面就可以遍曆取資訊了。

注意：啟動並執行前提是要修改瀏覽器安全設定，“允許對未標記為可安全執行的ActiveX
指令碼的運行”。
這裡主要取了CPU、記憶體及系統使用者幾個資訊，大家利用WMI的API或者藉助JSEDIT擷取
到更多的資訊。下面列出了常用資訊的類：

樣本：

複製代碼 代碼如下:

function button1_onclick() {//cpu 資訊
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 資訊
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() {//鍵盤資訊
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() {//主板資訊
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資訊：

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都是系統內建，不用去下載或註冊。
接下來的工作就是用指令碼和ActiveX互動

<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>
