JavaScript obtain information such as client computer hardware and system information

JavaScript obtain client computer hardware and system information

Through WMI to obtain client computer hardware and system information:

Copy code code as follows:

function getsysinfo () {

var local = New ActivexObject ("WBEMSCRIPTING.SWBEMLOCator");

var service = local.connectserver (".");

// CPU information

var cpu = new enumerator (service.execquery ("select * from win32_processor"). Item ();;);

var cpUtype = cpu.name, hostname = cpu.systemname;

// Memory information

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.itemm () .Speed}

// System information

var system = new enumerator (service.execquery ("select * from win32_computersystem"). item ();

Var PhysicMencap = Math.ceil (System.totalphysicalMemory/1024/1024), Curuser = System.Username, CPUCOUNT = System.numberProcessors

Return {CPUTYPE: CPUTYPE, CPUCOUNT: CPUCOUNT, Hostname: Hostname, Curuser: Curuser, Memcap: PhysicMencap, Mem: Mem}

}

Code implementation mainly includes these parts:

First pass the New Activexobject ("WBEMSCRIPTING.SWBEMLOCator"); access the WBEMScripting object.

Through local.connectserver (".");

You can also access other computers).

Through service.execquery ("Select * from Win32_processor"), a similar SQL statement (in fact, system information is also stored in a database -like file in calculations) to obtain the record set we need.

Create an enumerated object through New Enumertor, and you can traverse information below.

Note: The premise of running is to modify the safety settings of the browser, "allowing ActiveX, which is not marked as safe,"

The operation of the script ".

Here are the main information of CPU, memory, and system users.

Example:

Copy code code as follows:

Function Button1_ONCLICK () {// CPU information

var local = New ActivexObject ("WBEMSCRIPTING.SWBEMLOCator");

var service = local.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 ("<ter>");

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.SystemName +" </td> ");

document.write ("<TD>" + P.Processortype + "</td>");

document.write ("</tr>);

}

document.write ("</table>");

}

Function Button2_ONCLICK () {// CD-ROM information

var local = New ActivexObject ("WBEMSCRIPTING.SWBEMLOCator");

var service = local.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 ("<ter>");

document.write ("<TD>" + P.caption + "</td>");

document.write ("<TD>" " + P.Descript +" </td> ");

document.write ("<TD>" + P.Drive + "</td>");

document.write ("<TD>" " + P.Medialoaded +" </td> ");

document.write ("</tr>);

}

document.write ("</table>");

}

Function Button3_ONCLICK () {// Keyboard information

var service = local.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 ("<ter>");

document.write ("<TD>" " + P.Descript +" </td> ");

document.write ("<TD>" " + P.Name +" </td> ");

document.write ("<TD>" " + P.Status +" </td> ");

document.write ("</tr>);

Var Properties = Service.execquery ("Select * from Win32_baseboard");

var e = New Enumerator (Properties);

document.write ("<table border = 1>");

for (;! E.atend (); e.movenext ())

document.write ("<TD>" " + P. P. P. P. P." </td> ");

document.write ("<TD>" " + P.Version +" </td> ");

document.write ("</tr>);

}

document.write ("</table>");

}

In addition, you can also obtain the relevant information through the following ways:

Copy code code as follows:

<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] .txtMacadr.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 = object.macaddress;

if (ObjObject.iPenabled && Objobject.ipaddress (0)! = Null && Objobject.IPADDDRESS (0)! = "Undefined")

Ipaddr = object.ipaddress (0);

if (Objobject.dnshostname! = Null && Objobject.dnshostname! = "Undefined")

sdnsname = object.dnshostname;

}

</Script>

<Meta content = "mshtml 6.00.2800.1106" name = generator> </head>

<body>

<Object ID = local classid = clsid: 76A64158-CB41-11D1-8B02-00600806D9B6 Viewastext> </Object>

<Object ID = FOO Classid = CLSID: 75718C9A-F029-11D1-A1AC-004FB6C223> </Object>

<script language = jscript>

var service = local.connectserver ();

var macaddr;

var iPaddr;

var domainddr;

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"> </body> </html>

Copy code code as follows:

In fact, the most important thing is to use two ActiveX:

<Object ID = local classid = clsid: 76A64158-CB41-11D1-8B02-00600806D9B6 Viewastext> </Object>

<Object ID = FOO Classid = CLSID: 75718C9A-F029-11D1-A1AC-004FB6C223> </Object>

However, these two ActiveX are systematically built, without having to download or register.

The next job is to interact with ACTIVEX with scripts

<Html>

<head>

<script language = "javascript" type = "text/javascript">

function getcode () {

var local = New ActivexObject ("WBEMSCRIPTING.SWBEMLOCator");

var service = local.connectserver (".");

Var Properties = Service.execquery ("Select * from Win32_NetworkadapterConfiguration WHERE IPENABLD = TRUE");

var e = New Enumerator (Properties);

document.write ("<table border = 1>");

for (;! E.atend (); e.movenext ()) {

var p = e.item ();

//IF.IP.IPADDDRESS (0)!=Null && P.ipaddress (0)! = "Undefined" && P.IPADDDRESS (0)! = "0.0.0.0" && P.ipaddress (0)! = "127.0) .0.1 ") {{

document.write ("<ter>");

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>
