判断移动端并跳转到m域名的代码

<script>
    if (/(iPhone|iPad|iPod|iOS)/i.test(navigator.userAgent)) {
    
    window.location.href =window.location.href.replace("www","m");
    } else if (/(Android)/i.test(navigator.userAgent)) {
        window.location.href =window.location.href.replace("www","m");
    } 
  </script>

代码判断了当前环境的UA，如果是移动端，则将当前域名的www替换成m
