判断当前运行设备

1.根据设备加载不同地址系统

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";  
   if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {  
   window.location.href = "http://m.chekuaiping.com";   //移动端
 } else {  
     window.location.href = "http:baidu.com";  //PC端
   }  
 }
