dede判断手机访问电脑端网站跳转代码

这是我用在dede织梦程序上的代码，所以只要是php写的应该都可以用

<?php
////这段放手机站里
header("Cache-Control: no-cache"); 
header("Pragma: no-cache");
$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
$uachar = "/(symbianos|android|iphone|ucweb|blackberry)/i";
if($ua != '' && !preg_match($uachar, $ua)){
    echo 'window.location.href="https://www.domain.com";';
    exit();
}
?>

<?php
//这段放在电脑网站里
header("Cache-Control: no-cache"); 
header("Pragma: no-cache");
$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
$uachar = "/(symbianos|android|iphone|ucweb|blackberry)/i";
if($ua != '' && preg_match($uachar, $ua)){
    echo 'window.location.href="https://https://m.domain.com/";';
    exit();
}


?>

JS的写法

<script>
     var browser_class = navigator.userAgent;
     var browser_class_name1 = browser_class.match("Mobile");
     var browser_class_name2 = browser_class.match("mobile");
     var location_url = window.location.href;
     if (browser_class_name1 != null || browser_class_name2 != null){
         if (location_url.match("wap") == null){
         window.location.href="https://m.domain.com/";
         }
     } else
     {
        if (location_url.match("3g") != null || location_url.match("wap") != null){
        window.location.href="https://m.domain.com/";
        }
     }
</script>
