js判断当前浏览器是pc端还是移动端

根据用户的访问设备的不同来显示不同的页面样式，主要是判断移动设备还是电脑浏览器访问的。

下面给出js判断处理代码，以作参考。

<script type="text/javascript">
        function browserRedirect() {
            var sUserAgent = 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";
            document.writeln("您的浏览设备为：");
            if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {
                document.writeln("phone");
            } else {
                document.writeln("pc");
            }
        }

        browserRedirect();
    </script>
