Js本身无法，用Jquery去ajax一个后端地址，获得IP，就要获得了IP，就能知道是内网还是*了（内网一般都是192.168.XXX.XXX)

既然楼主用java的话

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.Authenticator;
import java.net.URL;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

import com.eehome.app.mail.IMailConstant;
import com.eehome.app.mail.model.RouterPassAuth;

/**

public class RouteIpUtils {

private final static RouteIpUtils routeIpUtils = new RouteIpUtils();

private RouteIpUtils() {

}

public static RouteIpUtils getInstance() {
//验证器工具的实例进行注册
Authenticator.setDefault(new RouterPassAuth());
return routeIpUtils;
}

public String getRouteIp() throws IOException {
StringBuffer wanPacket = getWanPacket();
return getFirstIp(wanPacket);
}

/**
* 获得路由Web中的状态页面上的数据
*
* @return
* @throws IOException
*/
private StringBuffer getWanPacket() throws IOException {
URL url = new URL(IMailConstant.ROUTE_WEB_STATE);
InputStream ins = null;
try {
ins = url.openConnection().getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(ins));
String str;
boolean flag = false;
StringBuffer wanPacket = new StringBuffer();
int num = 3;
while ((str = reader.readLine()) != null && num > 0) {
if (str.contains("var wanPara = new Array(")) {
flag = true;
}
if (flag) {
wanPacket.append(str);
num--;
}
}
return wanPacket;
}finally{
if(ins!=null){
ins.close();
}
}
}

private String getFirstIp(StringBuffer wanPacket) {
// 找出数据包中第一个匹配的IP,即为Ip
Pattern p = Pattern.compile("\\d+\\.\\d+\\.\\d+\\.\\d+");
Matcher m = p.matcher(wanPacket);
if (m.find()) {
return m.group();
} else {
return null;
}
}

public static void main(String[] args) {
try {
System.out.println(RouteIpUtils.getInstance().getRouteIp());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
然后调用我上面的方法，用servlet的response打印到网页上不就可以了吗
然后用js调用获取显示
