<script>
//var pcUrl = "http://res.meadin.com/HotelData/98986_1.shtml";
var pcUrl = window.location.href;
var str = (pcUrl.split("/")).slice(-1);
if((navigator.userAgent.match(/(iPhone|iPod|Android|ios)/i)) && (str[0].match(/^\d+_\d+.shtml$/g) !== null) ){window.location.href = "http:://m.meadin.com/index/index?url="+pcUrl;}
