第一种， jquery
var deviceAgent = navigator.userAgent.toLowerCase();
var agentID = deviceAgent.match(/(iphone|ipod|ipad|android)/);
if(agentID.indexOf("iphone")>=0){
alert("iphone");
}
if(agentID.indexOf("ipod")>=0){
alert("ipod");
}
if(agentID.indexOf("ipad")>=0){
alert("ipad");
}
if(agentID.indexOf("android")>=0){
alert("android");
}

第二种 Java：
Enumeration typestr = request.getHeaderNames();
String s1 = request.getHeader("user-agent");
if(s1.contains("Android")) {
System.out.println("Android移动客户端");
} else if(s1.contains("iPhone")) {
System.out.println("iPhone移动客户端");
} else if(s1.contains("iPad")) {
System.out.println("iPad客户端");
} else {
System.out.println("其他客户端");
}

} else if(s1.contains("iPad")) {
System.out.println("iPad客户端");
} else {

}

第二种情况测试下来，一般情况下可以满足需要，遇到像UC浏览器这些第三方浏览器，可能就不准了！
python, php, ror, .Net这些的话都可以借鉴第二种方式！
