Many Thanks!!
<script>
var QunarUtil=new function(){var prefix='/scripts/';var suffix='';var host='';if(location.host.indexOf('src.')!=-1){prefix='/scripts/src/';host='http://hstatic.qunar.com';suffix='.js';}else if(location.host.indexOf('enc.')!=-1){prefix='/scripts/';host='http://hstatic.qunar.com';suffix='.js';}else if(location.host.substring(0,10)=='sdev-'){prefix=location.host.substring(5,location.host.indexOf('.'));prefix='/'+prefix.replace(/\-/ig,'/');host='http://hstatic.qunar.com';suffix='.js';}else if(location.host.indexOf("h.qunar.com")!=-1){host='http://hstatic.qunar.com';suffix='';}
this.getScriptURL=function(name,isList){if(name.charAt(0)!='/')
return this.getScript(prefix+name,isList);else
return this.getScript(name,isList);}
this.getScript=function(src,isList){return'<'+'script type="text/javascript" src="'+host+src+(isList?suffix:'.js')+'?'+__QUNARVER__+'"></'+'script>';}

document.write(this.getScriptURL(list[i]));}
