JavaScript method to obtain client computer hardware and system information_javascript skills

JavaScript to obtain client computer hardware and system information
Acquire client computer hardware and system information through WMI:

Copy code The code is 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 access the WbemScripting object through new ActiveXObject ("WbemScripting.SWbemLocator");.
Connect to our local computer through locator.ConnectServer("."); (. represents the local computer, of course
can also access other computers).
Get the record set of the object we need through service.ExecQuery("SELECT * FROM Win32_Processor"), a SQL-like statement (in fact, the system information is also stored in a database-like file in the calculation).
Use new Enumerator to create an enumerable object, and then you can traverse to get the information.

Note: The prerequisite for running is to modify the browser security settings to "Allow the running of ActiveX
scripts that are not marked as safe for execution".
The main information here is CPU, memory and system user. You can use WMI API or JSEDIT to get
more information. Classes for common information are listed below:

Example:

Copy code The code is as follows:

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("");
for (;!e.atEnd();e.moveNext ())
{
var p = e.item ();
document.write("");
document.write("");
document.write("");
document.write("");
document.write("");
document.write("");
document.write("");
document.write("");
document.write("");
document.write("");
document.write("");
}
document.write("

" p.Caption "

" p.DeviceID "

" p.Name "

" p.CpuStatus "

" p.Availability "

");
}

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("");
for (;!e.atEnd();e.moveNext ())
{
var p = e.item ();
document.write("");
document.write("");
document.write("");
document.write("");
document.write("");
document.write("");
document.write("");
}
document.write("

" p.Caption "

" p.Description "

" p.Drive "

" p.Status "

" p.MediaLoaded "

");
}

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("");
document.write("");
document.write("");
}
document.write("

");
}

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("");
