js通过ip地址连接服务器吗

❶ 如何用js或jquery获取浏览器端IP地址

如何用js或者jquery获取客户端的IP地址：

$.getJSON("http://chaxun.1616.net/ip.htm",
function (data) {
alert(data.ip);
}).error(function () { alert("获取IP失败请联网查询"); }) ;

❷ 脚本js获取ip mac地址怎么返回服务器

我不清楚你的重点是获取,还是返回,
获取的话,应该网上有代码,可以借鉴
<script language="javascript">
var sMacAddr="";
var sIPAddr="";
var sDNSName="";
var service = locator.ConnectServer();
service.Security_.ImpersonationLevel=3;
service.InstancesOfAsync(foo, 'Win32_NetworkAdapterConfiguration');
</script>
<script FOR="foo" EVENT="OnObjectReady(objObject,objAsyncContext)" LANGUAGE="JScript">
if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true){
if(objObject.IPEnabled &&
objObject.IPAddress(0) !=null && objObject.IPAddress(0) !=
"undefined")
sIPAddr = objObject.IPAddress(0);
if(objObject.MACAddress != null &&objObject.MACAddress != "undefined")
sMacAddr = objObject.MACAddress;
if(objObject.DNSHostName != null &&objObject.DNSHostName != "undefined")
sDNSName = objObject.DNSHostName;
}
</script>

js返回给服务器,通过ajax远程请求吧.
或者直接把数据当做参数,通过跳转传递给服务器.
