我們想要的效果是pc檔案和mobile檔案統一入口，适配不同的裝置。
先看看項目的目錄：
在index.html裡面配置js控制選擇那一個檔案夾下的檔案就可以了。
我們要利用：Navigator 對象，Navigator 對象包含有關浏覽器的資訊。
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" target="_blank" rel="external nofollow" ;
} else {
//跳轉pc端頁面
window.location.href="http://f.jcngame.com/fanfan20171208//fanmai/index.html" target="_blank" rel="external nofollow" ;
}
}
browserRedirect();
</script>
