本文介绍了一段JavaScript代码，该代码仅适用于Internet Explorer浏览器，用于获取客户端的网卡MAC地址、IP地址及计算机名称。通过利用WMI（Windows Management Instrumentation）对象模型，实现跨页面的数据填充。

javascript获取客户端网卡MAC地址和IP地址和计算机名，只能在IE下使用，代码如下：

<HTML>
<HEAD><TITLE>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>
</HEAD>
<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 name="txtMACAddr"> <br>
    <INPUT name="txtIPAddr"><br>
    <INPUT name="txtDNSName"></FORM>
