JavaScript 获取客户端计算机硬件及系统信息

浏览器信息

[javascript]
view plain copy

//浏览器信息

function BrowserInfo() {

var userLanguage = navigator.userLanguage; // 用户在自己的操作系统上设置的语言（火狐没有）

var userAgent = navigator.userAgent; //包含以下属性中所有或一部分的字符串：appCodeName,appName,appVersion,language,platform

var systemLanguage = navigator.systemLanguage; // 用户操作系统支持的默认语言（火狐没有）

var info = "";

info += "浏览器属性信息： " + userAgent + "<br />";

info += "用户设置的操作系统语言： " + userLanguage + "<br />";

info += "操作系统支持的默认语言： " + systemLanguage + "<br />";

return info;

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
