JS代码判断访问网站客户端的操作系统，实现跳转

<script type="text/javascript">

function uaredirect(){ 
//平台、设备和操作系统

var  system={win:false,mac:false,xll:false,iPhone:false,iPad:false,ios:false};
//检测平台
var p = navigator.platform;
system.win = p.indexOf("Win") == 0;
system.mac = p.indexOf("Mac") == 0;
system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
system.iPhone = p.indexOf("iPhone") == 0;
system.iPad = p.indexOf("iPad") == 0;
system.ios = p.indexOf("ios") == 0;
//跳转语句
if(system.win||system.mac||system.xll||system.iPhone||system.iPad||system.ios){

}else
{
window.location.href="index.asp";
}
} 

 

</script>

<script type="text/javascript">uaredirect();</script>
