<script type="text/javascript">

            function browserRedirect() {

              var sUserAgent = navigator.userAgent.toLowerCase();

              console.log(sUserAgent);

              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>

直接将这段代码放进去，在页面一打开的时候就可以判断出是什么打开了。

navigator.包含用户的全部信息
userAgent.属性方法 可返回从客户端到服务端的user-agent的值
toLowerCase()将获取到的信息全部转化为小写的
