For example, js gets local and public IP addresses.

  1. <scrip去掉t language="javascrip去掉t" type="text/javascrip去掉t">
  2. //获取本地IP
  3. function GetLocalIPAddress()
  4. { var obj = null; var rslt = "";
  5. try{ obj = new ActiveXObject("rcbdyctl.Setting");
  6. rslt = obj.GetIPAddress; obj = null; }
  7. catch(e)
  8. { alert("ErrInfoIS:"+e) } return rslt; }
  9. document.write("你的IP是：" + GetLocalIPAddress());
  10. </scrip去掉t>
Copy code

The above is how js obtains a local IP address, let's take a look at an example of js obtaining an external IP address.


  1. <scrip去掉t language="javascrip去掉t">
  2. //获取外网IP
  3. xml=new ActiveXObject("Microsoft.XMLHTTP");
  4. xml.open("GET","http://city.ip138.com/city0.asp",false);
  5. xml.send(); kk=xml.ResponseText;
  6. i=kk.indexOf("["); ie=kk.indexOf("]");
  7. ip=kk.substring(i+1,ie); document.write("<span style='color:red;font-size:12;' cursor='hand'>您的IP地址是:" + ip + "</span>"); </scrip去掉t>
Copy code
