前提要引入百度API：<script src="http://api.map.baidu.com/api?v=1.4"
type="text/javascript"></script>。
2. PC端通过IP实现方法：
采用腾讯提供的接口，这个目前已经不能使用。
<script type="text/javascript" src="http://fw.qq.com/ipaddress"></script>
<script type="text/javascript">
document.write(IPData[0]) //显示IP地址
document.write(IPData[2]) //显示省
document.write(IPData[3]) //显示市
</script>
3 . 获取客户端IP方法
<script>
var url = 'http://chaxun.1616.net/s.php?type=ip&output=json&callback=?&_=' + Math.random()
$.getJSON(url, function(data) {
alert(data.Ip)
})
</script>
