JavaScript判断设备是移动还是PC代码

<script type="text/javascript">function browserRedirect() { var sUserAgent= navigator.userAgent.toLowerCase(); var bIsIpad= sUserAgent.match(/ipad/i) == "ipad"; var bIsIphoneOs= sUserAgent.match(/iphone os/i) == "iphone os"; var bIsMidp= sUserAgent.match(/midp/i) == "midp"; var bIsUc7= sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4"; var bIsUc= sUserAgent.match(/ucweb/i) == "ucweb"; var bIsAndroid= sUserAgent.match(/android/i) == "android"; var bIsCE= sUserAgent.match(/windows ce/i) == "windows ce"; var bIsWM= sUserAgent.match(/windows mobile/i) == "windows mobile";  if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) { alert('WAP');//window.location.href= '手机站链接'; } else { alert('PC');//window.location= 'PC站链接'; } } browserRedirect(); </script>
