<script type="text/javascript">
wapurl="http://test.com/";if(window.location.toString().indexOf('pref=padindex')!=-1){}else{if(/AppleWebKit.*Mobile/i.test(navigator.userAgent)||(/MIDP|SymbianOS|NOKIA|SAMSUNG|LG|NEC|TCL|Alcatel|BIRD|DBTEL|Dopod|PHILIPS|HAIER|LENOVO|MOT-|Nokia|SonyEricsson|SIE-|Amoi|ZTE/.test(navigator.userAgent))){if(window.location.href.indexOf("?mobile")<0){try{if(/Android|Windows Phone|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)){window.location.href=wapurl}else if(/iPad/i.test(navigator.userAgent)){window.location.href=wapurl}else{window.location.href=wapurl}}catch(e){}}}}
