我们想要的效果是pc文件和mobile文件统一入口，适配不同的设备。
先看看项目的目录：

JS,判断,手机端,PC端

在index.html里面配置js控制选择那一个文件夹下的文件就可以了。
我们要利用：Navigator 对象，Navigator 对象包含有关浏览器的信息。
index.html很简单，直接上码吧：

<!DOCTYPE html><html>	<head>		<meta charset="UTF-8">		<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no" />		<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";	  if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {	  //跳转移动端页面	  window.location.href="http://f.jcngame.com/fanfan20171208/mobile/index.html" rel="external nofollow" rel="external nofollow" ;	  } else {	  //跳转pc端页面	  window.location.href="http://f.jcngame.com/fanfan20171208//fanmai/index.html" rel="external nofollow" rel="external nofollow" ;	  }	 }			browserRedirect(); 		</script>	</head>	<body>			</body></html>

补充，感觉之前代码太冗余了，现在用正则来优化了一下：

<script type="text/javascript">	function browserRedirect() {  var sUserAgent = navigator.userAgent.toLowerCase();  if (/ipad|iphone|midp|rv:1.2.3.4|ucweb|android|windows ce|windows mobile/.test(sUserAgent)) {  //跳转移动端页面  window.location.href="http://f.jcngame.com/fanfan20171208/mobile/index.html" rel="external nofollow" rel="external nofollow" ;  } else {  //跳转pc端页面  window.location.href="http://f.jcngame.com/fanfan20171208//fanmai/index.html" rel="external nofollow" rel="external nofollow" ;  } }	browserRedirect(); </script>
