JavaScript access to information such as client computer hardware and systems _javascript tips

JavaScript access to client computer hardware and system Information
Access to client computer hardware and system information through WMI:

Copy Code code as follows:

function Getsysinfo () {
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
var service = Locator. 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.item (). 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. NumberOfProcessors

return {CPUTYPE:CPUTYPE,CPUCOUNT:CPUCOUNT,HOSTNAME:HOSTNAME,CURUSER:CURUSER,MEMCAP:PHYSICMENCAP,MEM:MEM}
}

The code implementation mainly includes these parts:

First through the new ActiveXObject ("WbemScripting.SWbemLocator"); Access to the WbemScripting object.
Through the locator. ConnectServer ("."); Connect our local computer (. On behalf of the local computer, of course
You can also access other computers).
Through service. ExecQuery ("SELECT * from Win32_Processor") This SQL-like statement (in fact the system information is stored in a similar database file in the calculation) gets the recordset of the object we need.
With the new enumerator to create an enumerable object, you can iterate through the information below.

Note: The prerequisite for running is to modify browser security settings, "Allow ActiveX that is not marked for safe execution
Script run. "
This mainly takes CPU, memory and system user several information, everybody utilizes WMI's API or uses the Jsedit to obtain
to more information. The following lists the classes for common information:

Win32_Processor//CPU processor

Example:

Copy Code code as follows:

function Button1_onclick () {//CPU information
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 information
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 () {//keyboard information
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 () {//motherboard information
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>");
}

In addition, information about the system can be obtained in the following ways:

Copy Code code as follows:

&LT;HTML&GT;&LT;HEAD&GT;&LT;TITLE&GT;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><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>

Copy Code code as follows:

In fact, the key is to use two ActiveX:
<object Id=locator Classid=clsid:76a64158-cb41-11d1-8b02-00600806d9b6 viewastext></object>
<object Id=foo classid=clsid:75718c9a-f029-11d1-a1ac-00c04fb6c223></object>
However, these two ActiveX systems are self-contained and do not need to be downloaded or registered.
The next task is to use scripting and ActiveX interaction

<HTML>
<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>
<BODY>
<button id= "test" value= "test" onclick= "GetCode ()" >TEST</button>
</BODY>
