JS 判断浏览器客户端类型(ipad,iphone,android)

//平台、设备和操作系统 
var system = { 
    win: false, 
    mac: false, 
    xll: false, 
    ipad: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.ipad = (navigator.userAgent.match(/iPad/i) != null)?true:false; 
//跳转语句，如果是手机访问就自动跳转到wap.baidu.com页面 
if (system.win || system.mac || system.xll||system.ipad) { 

} else { 

    window.location.href = "http://www.jdpatro.com/3g/";

如何判断访问网站的机器类型-如何判断ipad

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/531.21.10

function is_iPad(){        
 [object Object] [object Object] [object Object]var ua = navigator.userAgent.toLowerCase();
 [object Object] [object Object] [object Object]if(ua.match(/iPad/i)=="ipad") {                
 [object Object] [object Object] [object Object] [object Object] [object Object] [object Object]return true;
 [object Object] [object Object] [object Object]} else {
 [object Object] [object Object] [object Object] [object Object] [object Object] [object Object]return false;
 [object Object] [object Object] [object Object]}
}


$is_iPad = (bool) strpos($_SERVER['HTTP_USER_AGENT'],'iPad');

RewriteCond %{HTTP_USER_AGENT} ^.*iPad.*$
RewriteRule ^(.*)$ http://ipad.fairyfish.net [R=301]
