JS get the network IP address of this machine

JavaScript is a scripting language that can't manipulate files and read local information, so you want to get IP, and you need back-end technology. Here's how:

//获取本机的网络ip地址function jsonpCallback(res) {    var ip = res.Ip;    // ip地址    var aa = res.Isp.split("市");    var isp = aa[0];    // ip省份    alert(ip);}function getIntnetIP() {    var JSONP=document.createElement("script");    JSONP.type="text/javascript";    JSONP.src="http://chaxun.1616.net/s.php?type=ip&v=&output=json&callback=jsonpCallback";    document.getElementsByTagName("head")[0].appendChild(JSONP);}getIntnetIP();

The implementation principle is to access a network address, through the backend to get to your network IP, back to the front end.
