页面表奇数据通过AJAX传到后台，中文取不到值？为什么

         var userindex = WebClient.Store[0].UserIndex;
      var name = $("name-input").value;
        var phone = $("phone-input").value;
        var babyname = $("babyname-input").value;
        var password = $("password-input").value;
            
         var url = "php/login.php
action=Modify&UserIndex="+userindex+"&Name="+name+"&Phone="+phone+"&BabyName="+babyname+"&Password="+password+"&random="+Math.random();

    $name = "";
    if(array_key_exists('Name',$_GET))
    {
        $name = trim($_GET['Name']);
    }
