如何用js判断是否为手机访问

<script type="text/javascript">

var ua = navigator.userAgent;

var ipad = ua.match(/(iPad).*OS\s([\d_]+)/),

isIphone =!ipad && ua.match(/(iPhone\sOS)\s([\d_]+)/),

isAndroid = ua.match(/(Android)\s+([\d.]+)/),

isMobile = isIphone || isAndroid;

//判断

if(isMobile){

}else{

}

</script>
