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]
