JS代码如下：
function browerType() {
var sUserAgent = navigator.userAgent.toLowerCase(); //浏览器的用户代理设置为小写，再进行匹配
var isIpad = sUserAgent.match(/ipad/i) == "ipad"; //或者利用indexOf方法来匹配
var isIphoneOs = sUserAgent.match(/iphone os/i) == "iphone";
var isMidp = sUserAgent.match(/midp/i) == "midp"; //移动信息设备描述MIDP是一套Java应用编程接口，多适用于塞班系统
var isUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4"; //CVS标签
var isUc = sUserAgent.match(/ucweb/i) == "ucweb";
var isAndroid = sUserAgent.match(/android/i) == "android";
var isCe = sUserAgent.match(/windows ce/i) == "windows ce";
var isWM = sUserAgent.match(/windows mobil/i) == "windows mobil";
if (isIpad || isIphoneOs || isMidp || isUc7 || isUc || isAndroid || isCe || isWM) {
alert(‘该设备为移动设备‘);
} else {
alert(‘该设备为PC设备‘);
}
}
browerType();
