js根據IP地址獲取當前的省市
3.阿里巴巴提供了介面，但不支援js跨域請求回撥，我們可以在java程式碼中請求，返回引數：

js:客戶端呼叫java後臺
<script type="text/javascript">
$(function(){
var ipServer = "localhost:8080/projectweb";
$.ajax({
url:ipServer+"/public/ipquery/getIpInfo?callback=?",
async :false,
dataType:"jsonp",
type:'get',
success:function(data){
console.log(data)
},
error:function(XMLHttpRequest, textStatus, errorThrown) {
console.log(XMLHttpRequest.status);
console.log(XMLHttpRequest.readyState);
console.log(textStatus);
}
});
}
</script>
data 的內容：
{"nation":"中國","city":"蘭州","cityCode":"620100","provice":"甘肅","isp":"電信","proviceCode":"620000","type":"taobao","status":"0"}
2.根據搜狐提供的API獲取當前的地區：
<script src="http://pv.sohu.com/cityjson?ie=utf-8"></script>呼叫該API返回值為：
var returnCitySN = {"cip": "42.91.160.**", "cid": "620000", "cname": "甘肅省"};$(document).ready(function(){
var areaCode = returnCitySN["cid"]; //地區編碼
var thisIp = returnCitySN["cip"]; //IP
var areaName = returnCitySN["cname"]; //只能獲取到省
}
1.根據新浪提供的API獲取：
<script src="http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js"></script>呼叫該API 返回值：
var remote_ip_info = {"ret":1,"start":-1,"end":-1,"country":"\u4e2d\u56fd","province":"\u7518\u8083","city":"\u5170\u5dde","district":"","isp":"","type":"","desc":""};$(document).ready(function(){
alert("當前地區"+remote_ip_info["province"]+"省"+remote_ip_info["city"]+"市"+remote_ip_info["district"]+"區");
｝注：新浪的暫時不能用了，請大家參考搜狐的或阿里巴巴的
