Question

我尝试从data属性获取值并将其传递给java脚本变量，但它给出了未定义的值

    $(document).on("click","#edit_cust",function(){
        var customer_id=$(this).data("id");
        var customer_name=$(this).data("name");
        var customer_phone=$(this).data("phone");
        var customer_addr=$(this).data("mail");
        var customer_mail=$(this).data("phone");   
    });

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class='btn-group' role='group' >
     <a id="edit_cust" data-target="#edit" data-toggle="modal"><button 
     type='button' class='btn btn-primary btn-sm' data-id="<?php echo 
     $customer["cus_id"]; ?>" data-name="<?php echo $customer["cus_name"]; ?>" 
     data-phone="<?php echo $customer["cus_phone"]; ?>" data-addr="<?php echo 
     $customer["cus_address"]; ?>" data-mail="<?php echo $customer["cus_mail"]; ? 
     >"><span class="fas fa-user-edit edit_data" aria-hidden='true'></span> 
     </button></a>
    </div>

所有这些数据属性都存在于内部public static Function<Integer, Double> tariff = t -> { if (t = 500) { t * t; } else { t + t; } };中，因此请在单击的元素内获取button。
