如何判断是否是 iPad 浏览器呢，关键是看它的 User Agent 中是否有 iPad。iPad 使用的是 Safari Mobile 浏览器，他的的 User Agent 是：

Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10Javascript代码function is_iPad(){     var ua = navigator.userAgent.toLowerCase();     if(ua.match(/iPad/i)=="ipad") {        return true;     } else {        return false;     } }因此，判断ipad,iphone,android的代码为：

<script type="text/javascript"> 
varbForcepc = fGetQuery("dv") =="pc"; 
functionfBrowserRedirect(){  
    varsUserAgent = navigator.userAgent.toLowerCase();  
    varbIsIpad = sUserAgent.match(/ipad/i) == "ipad";   
    varbIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os"; 
    varbIsMidp = sUserAgent.match(/midp/i) == "midp"; 
    varbIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4"; 
    varbIsUc = sUserAgent.match(/ucweb/i) == "ucweb"; 
    varbIsAndroid = sUserAgent.match(/android/i) == "android"; 
    varbIsCE = sUserAgent.match(/windows ce/i) == "windows ce"; 
    varbIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile"; 
    if(bIsIpad){ 
        varsUrl = location.href;      
        if(!bForcepc){ 
            window.location.href ="http://ipad.mail.163.com/"; 
        } 
    } 
    if(bIsIphoneOs || bIsAndroid){ 
        varsUrl = location.href;      
        if(!bForcepc){ 
            window.location.href ="http://smart.mail.163.com/"; 
        } 
    } 
    if(bIsMidp||bIsUc7||bIsUc||bIsCE||bIsWM){ 
        varsUrl = location.href;      
        if(!bForcepc){ 
            window.location.href ="http://m.mail.163.com/"; 
        } 
    } 
}  
functionfGetQuery(name){//获取参数值 
    varsUrl = window.location.search.substr(1);  
    varr = sUrl.match(newRegExp("(^|&)"+ name + "=([^&]*)(&|$)")); 
    return(r == null? null: unescape(r[2]));  
}  
functionfShowVerBlock(){     
    if(bForcepc){ 
        document.getElementById("dv_block").style.display ="block"; 
    } 
    else{ 
        document.getElementById("ad_block").style.display ="block"; 
    } 
}  
fBrowserRedirect(); 
</script>
