window.navigator.userAgent用来区分设备和浏览器_window.navigator.useragent.match

var sUserAgent = window.navigator.userAgent.toLowerCase();
                            var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
                            var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
                            var bIsMidp = sUserAgent.match(/midp/i) == "midp";
                            var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
                            var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
                            var bIsAndroid = sUserAgent.match(/android/i) == "android";
                            var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
                            var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
                            if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {

                            }
