javascript获取客户端网卡MAC地址和IP地址和计算机名

在做
B/S
结构的系统时,我们常常需要获取客户端的一些信息,如
IP
和
MAC
,以结合身份验证。
要获取服务器端的
MAC
很容易,但是要获取客户端的
MAC
的地址确要花费一翻心思,通常的做法是调用
Win32API
或直接调用
nbtstat
命令,这样做有很多问题,而另一种方法就是直接用客户端脚本,我们这里用
Javascript
,这样做的好处是不需要服务器端进行处理,有客户端自行获取,传递到服务器端,且速度和可靠性都比在服务器端获取好。
具体实现的html和javascript如下:
其实最关键的还是用到两个ActiveX:
<OBJECT id=locator classid=CLSID:76A64158-CB41-11D1-8B02-00600806D9B6 VIEWASTEXT></OBJECT>
<OBJECT id=foo classid=CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223></OBJECT>
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
