javascript 获取客户端计算机硬件及系统信息
通过wmi来实现获取客户端计算机硬件及系统信息:
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;
//内存信息
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}
//系统信息
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}
}
代码实现主要包括这几部分：
先通过new activexobject (wbemscripting.swbemlocator); 访问到wbemscripting对象。
通过locator.connectserver(.);连接我们本地电脑（.代表本地电脑，当然
也可以访问其他计算机）。
通过service.execquery(select * from win32_processor)这个类似sql的语句（其实系统信息也是存储在计算中一个类似数据库的文件中）获取我们需要的对象的记录集。
通过new enumerator来创建一个可枚举的对象，下面就可以遍历取信息了。
注意：运行的前提是要修改浏览器安全设置，“允许对未标记为可安全执行的activex
脚本的运行”。
这里主要取了cpu、内存及系统用户几个信息，大家利用wmi的api或者借助jsedit获取
到更多的信息。下面列出了常用信息的类：
win32_processor // cpu 处理器
win32_physicalmemory // 物理内存
win32_keyboard // 键盘
win32_pointingdevice // 点输入设备，如鼠标
win32_diskdrive // 硬盘驱动器
win32_cdromdrive // 光盘驱动器
win32_baseboard // 主板
win32_bios // bios 芯片
win32_parallelport // 并口
win32_serialport // 串口
win32_sounddevice // 多媒体设置

win32_potsmodem // modem
win32_potsmodemtoserialport // modem 端口
win32_desktopmonitor // 显示器
win32_videocontroller // 显卡细节。
win32_videosettings // 显卡支持的显示模式。
win32_timezone // 时区
win32_systemdriver // 驱动程序
win32_diskpartition // 磁盘分区
win32_logicaldisk // 逻辑磁盘
win32_logicalmemoryconfiguration // 逻辑内存配置
win32_pagefile // 系统页文件信息
win32_pagefilesetting // 页文件设置
win32_bootconfiguration // 系统启动配置
win32_operatingsystem // 操作系统信息
win32_startupcommand // 系统自动启动程序
win32_service // 系统安装的服务
win32_group // 系统管理组
win32_groupuser // 系统组帐号
win32_useraccount // 用户帐号
win32_process // 系统进程
win32_thread // 系统线程
win32_share // 共享
win32_networkclient // 已安装的网络客户端

示例：
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( + p.caption + );
document.write( + p.deviceid + );
document.write( + p.name + );
document.write( + p.cpustatus + );
document.write( + p.availability + );
document.write( + p.level + );
document.write( + p.processorid + );
document.write( + p.systemname + );
document.write( + p.processortype + );
document.write(
);
}
document.write(
);
}
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( + p.caption + );
document.write( + p.description + );
document.write( + p.drive + );
document.write( + p.status + );
document.write( + p.medialoaded + );
document.write(
);
}
document.write(
);
}
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();
for (;!e.atend();e.movenext ())
{
var p = e.item ();
document.write();
document.write( + p.description + );
document.write( + p.name + );
document.write( + p.status + );
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();
for (;!e.atend();e.movenext ())
{
var p = e.item ();
document.write();
document.write( + p.hostingboard + );
document.write( + p.manufacturer + );
document.write( + p.poweredon + );
document.write( + p.product + );
document.write( + p.serialnumber + );
document.write( + p.version + );
document.write(
);
}
document.write(
);
}
另外，通过以下方式也可以获得系统的相关信息：
wmi scripting html
其实最关键的还是用到两个activex：
不过这两个activex都是系统自带，不用去下载或注册。
接下来的工作就是用脚本和activex交互
