呃呃，直接上代码了：

<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) {

window.location.href= ’手机网站地址’;

} else {

window.location= ’电脑网站地址’;

}

}

browserRedirect();

</script>
