我們想要的效果是pc文件和mobile文件統一入口，適配不同的設備。
先看看項目的目錄：

在index.html里面配置js控制選擇那一個文件夾下的文件就可以了。
我們要利用：Navigator 對象，Navigator 對象包含有關瀏覽器的信息。
index.html很簡單，直接上碼吧：

<!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) {	  //跳轉移動端頁面	  window.location.href="http://f.jcngame.com/fanfan20171208/mobile/index.html" rel="external nofollow" rel="external nofollow" ;	  } else {	  //跳轉pc端頁面	  window.location.href="http://f.jcngame.com/fanfan20171208//fanmai/index.html" rel="external nofollow" rel="external nofollow" ;	  }	 }			browserRedirect(); 		</script>	</head>	<body>			</body></html>

補充，感覺之前代碼太冗余了，現在用正則來優化了一下：

<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)) {  //跳轉移動端頁面  window.location.href="http://f.jcngame.com/fanfan20171208/mobile/index.html" rel="external nofollow" rel="external nofollow" ;  } else {  //跳轉pc端頁面  window.location.href="http://f.jcngame.com/fanfan20171208//fanmai/index.html" rel="external nofollow" rel="external nofollow" ;  } }	browserRedirect(); </script>
