判断是移动还是pc，判断是否是微信浏览器

function IsPC()  
                {  
                                   var userAgentInfo = navigator.userAgent;  
                                   var Agents = new Array("Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod");  
                                   var flag = true;  
                                   for (var v = 0; v < Agents.length; v++) {  
                                           if (userAgentInfo.indexOf(Agents[v]) > 0) { flag = false; break; }  
                                   }  
                                   return flag;  
                }  



判断返回结果，来执行脚本；flag=true 为pc；false为移动


<script type="text/javascript">
                                        window.onload = function(){
                                    if(!isWeiXin()){
                                        window.location.href="baidu.com";
                                    }
                                }

                                //判断是否是微信浏览器
                                function isWeiXin(){
                                    var ua = window.navigator.userAgent.toLowerCase();
                                    if(ua.match(/MicroMessenger/i) == 'micromessenger'){
                                        return true;
                                    }else{
                                        return false;
                                    }
                                }
                        </script>
