用js获取本地电脑信息（但是只能在IE浏览器下才行，其他浏览器其获取不到的）：
复制代码 代码如下:

<script type="text/javascript">
window.onload = getusername;
function getusername(){
//js获取电脑信息
var WshNetwork = new ActiveXObject("WScript.Network");
var WshShell = new ActiveXObject ("WScript.Shell");
var $lDomain = document.getElementById('lDomain'),
$lcName = document.getElementById('lcName'),
$luName = document.getElementById('luName'),
$lDomainDn = document.getElementById('lDomainDn');
$lDomain.value =WshNetwork.UserDomain;
$lcName.value =WshNetwork.ComputerName;
$luName.value =WshNetwork.UserName;
$lDomainDn.value =WshShell.RegRead ("HKCUVolatile EnvironmentUSERDNSDOMAIN");
WshNetwork = null;
WshShell = null;
};
</script>
</head>
<body>
<input type='text' id='lDomain' value='' />
