javascript - 使用 php 单击打开模态的 anchor 标记时获取模态上​​的 id

Question

我有一个点击 anchor 标记时打开的模式，并使用 javascript 在输入隐藏字段中传递 id 值，并且值显示在此隐藏字段中

    <a href="#modal2" data-toggle="modal" data-id="<?php echo $CRow['id'];?>" 
id="<?php echo $CRow['id'];?>" class="btn-floating 
waves-effect waves-light yellow modal-trigger" title="Test"></a>
        <div id="modal2" class="modal">
             <form action="lst_applicant.php" method="post" enctype="multipart/form-data">
                 <div class="modal-content">
                     <input type="hidden" id="applicantid" name="applicantid" value="" />
                     <p>Applicant Information</p>
                     <?php  
                         $applicant_detail=mysql_query("select * from tbl_useraccount where id=".$applicantid); 
                     ?>
                 </div>
                      <div class="modal-footer">
                          <button type="submit" name='save' class="btn waves-effect waves-light right modal-close">Save</button>
                      </div>
                   </form> 
               </div>

    Here is the code of javascript passing the id value in input hidden field

        <script>
            $(document).on("click", ".modal-trigger", function () {
            var myBookId = $(this).data('id');
            $(".modal-content #applicantid").val( myBookId );
          });
        </script>

问题是，当我在隐藏字段中获取 id 但无法获取 php 变量时。打开模态时如何获取模态上​​的 id？

当我单击 anchor 标记打开模态时，在模态上有一个输入隐藏字段，在该隐藏字段中使用 javascript 显示每个 anchor 标记的 id 值，我希望当该隐藏字段获取 id 值时如何进入php变量？我正在获取 php 变量，但它不起作用

您可以获取这样的数据，您只需在anchor modal data中提供详细信息即可

data-id="<?php echo $CRow['id'];?>"以及名称data-name="<?php echo $CRow['name'];?>"等等

$(document).on("click", ".modal-trigger", function () {
  var myBookId = $(this).data('id');
  var name = $(this).data('name');
  var email = $(this).data('email');
  $(".modal-content #applicantid").val( myBookId );
  $("#appli_name").val(name);
  $("#appli_email").val(email);
});
