如何获得jquery和模态窗口的按钮ID？

Question

我有一个HTML表单,单击该按钮将生成一个模态窗口.按钮如下.

<button type="button" class="btn" id="gs_one" data-toggle="modal" data-target="#BASIC">Get Started</button>

启动的模态类型将是"基本"类型.Modal实际上是另一种形式,然后通过POST方法提交给另一个PHP页面.模态如下.

<div class="modal fade" id="BASIC" role="dialog">
   <div class="modal-dialog modal-lg">
      <div class="modal-content">
         <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal">&times;</button>
            <h4 class="modal-title">Header</h4>
         </div>
         <div class="modal-body">
            <form class="contact-work-form2 mar" id="contact-form" action="" method="post">
               <div class="text-input">
                  <div class="float-input">
                     <input type="text" placeholder="Name" id="name2" name="name" required>
                  </div>
                  <div class="float-input2">
                     <input type="text" placeholder="Email" id="mail2" name="mail" required>
                  </div>
               </div>
               <div class="text-input">
                  <div class="float-input">
                     <input type="text" placeholder="Phone" id="phone" name="phone" required>
                  </div>
                  <div class="float-input2">
                     <input type="text" placeholder="Company" id="company" name="company" required>
                  </div>
               </div>
               <div class="text-input">
                  <div class="float-input1">
                     <input type="text" required name="country" id="country" placeholder="Country">
                  </div>
               </div>
               <input type="submit" value="Submit" class="submit_contact main-form" name="mailing-submit">
            </form>
         </div>
         <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
         </div>
      </div>
   </div>
</div>

我可以POST到PHP页面.但是,在发布时,我还需要传递一个变量,该变量具有启动模态的按钮的值或ID.

你可以访问按钮ID

$(document).ready(function(){
  $('.btn').click(function(){
    var a=$(this).attr('id');
    alert(a);
  });
});
