我有用戶列表：

當我點擊PM按鈕，我得到javascipt的sceen：

如何填寫的Javascript屏幕領域與用戶價值自動列出並將值發送到其他PHP文件（使用AJAX）？

用戶名單表的代碼：

所有的

 <!-- Table -->

     <tr class="bg_h">

首先，你不`噸需要在表中每一行一個模式對話框。從for-each循環中取出它。 另外，爲每個@PM按鈕添加一個類以便於選擇。以後，將一些操作綁定到@PM按鈕單擊事件。這裏是代碼，請確保jquery已加載。

foreach ($list as $row) { 
     ?> 
     <tr class=""> 
      <td><?php echo $row['user_name']; ?></td> 
      <td><?php echo $row['user_email']; ?></td> 
      <td> 
      <?php 
      //PHP code of getting user rank. 
      ?> 
      </td> 
      <td> 
      <?php 
      //PHP code to chech is user active. 
      ?> 
      </td> 
      <td> 
       <?php echo $row['user_registration_datetime']; ?> 
      </td> 
      <td> 
       <?php echo $row['user_registration_ip']; ?> 
      </td>
