我有一个ajax更新特性，其中有一些特定的问题，我确信这只需要一些调整，然后它就可以100%地工作

   <!-- Modal content-->
   <div class="modal-content" style="width: 300px; margin: 0 auto;">
     <div class="modal-header">
       <button type="button" class="close" data-dismiss="modal">&times;</button>
     </div>
     <div class="modal-body">
       <div class="form-group">
         <a href="#" id="update_yes" class="btn btn-success text-center center-block">YES</a><br>
         <a href="#" id="update_no" class="btn btn-danger text-center center-block">NO</a><br>
         <a href="#" id="update_cancelled" class="btn btn-warning text-center center-block">CANCEL</a>
       </div>

     </div>
   </div>

 </div>

我将尽可能清楚地总结以下问题

   <!-- Modal content-->
   <div class="modal-content" style="width: 300px; margin: 0 auto;">
     <div class="modal-header">
       <button type="button" class="close" data-dismiss="modal">&times;</button>
     </div>
     <div class="modal-body">
       <div class="form-group">
         <a href="#" id="update_yes" class="btn btn-success text-center center-block">YES</a><br>
         <a href="#" id="update_no" class="btn btn-danger text-center center-block">NO</a><br>
         <a href="#" id="update_cancelled" class="btn btn-warning text-center center-block">CANCEL</a>
       </div>

     </div>
   </div>

我有两个相互交互的文件：

   <!-- Modal content-->
   <div class="modal-content" style="width: 300px; margin: 0 auto;">
     <div class="modal-header">
       <button type="button" class="close" data-dismiss="modal">&times;</button>
     </div>
     <div class="modal-body">
       <div class="form-group">
         <a href="#" id="update_yes" class="btn btn-success text-center center-block">YES</a><br>
         <a href="#" id="update_no" class="btn btn-danger text-center center-block">NO</a><br>

我的ajax尝试根据单击的按钮更新表int值。否=0，是=1，取消=2

SQL更新

 if(isset($_POST['id'])){

  $orderid = $_POST['id'];
  $scheduled = $_POST['scheduled'];

  $stmt = $db->prepare("UPDATE order SET scheduled = '$scheduled' WHERE orderid = '$orderid'");
  $stmt->execute(); }

问题

   <!-- Modal content-->
   <div class="modal-content" style="width: 300px; margin: 0 auto;">

       </div>

     </div>
   </div>

上面的SQL代码没有更新表（屏幕截图中显示的那一个，但ajax只是从成功函数中更新按钮的外观（当页面刷新时它会返回到其原始值）。我想知道问题是什么。它应该连接到按钮，因为它使用的是“if（isset（$\u POST['id']）”

   <!-- Modal content-->
   <div class="modal-content" style="width: 300px; margin: 0 auto;">
     <div class="modal-header">
       <button type="button" class="close" data-dismiss="modal">&times;</button>
     </div>
     <div class="modal-body">
       <div class="form-group">
         <a href="#" id="update_yes" class="btn btn-success text-center center-block">YES</a><br>
         <a href="#" id="update_no" class="btn btn-danger text-center center-block">NO</a><br>
         <a href="#" id="update_cancelled" class="btn btn-warning text-center center-block">CANCEL</a>
       </div>

     </div>
   </div>

我希望我已经清楚地解释了我的两个问题，谢谢你的帮助

   <!-- Modal content-->
   <div class="modal-content" style="width: 300px; margin: 0 auto;">
     <div class="modal-header">
       <button type="button" class="close" data-dismiss="modal">&times;</button>
     </div>
     <div class="modal-body">
       <div class="form-group">
         <a href="#" id="update_yes" class="btn btn-success text-center center-block">YES</a><br>
         <a href="#" id="update_no" class="btn btn-danger text-center center-block">NO</a><br>
         <a href="#" id="update_cancelled" class="btn btn-warning text-center center-block">CANCEL</a>
       </div>

     </div>
   </div>

 </div>

更新我使用下面的代码检查按钮更新是否有错误：

   <!-- Modal content-->
   <div class="modal-content" style="width: 300px; margin: 0 auto;">
     <div class="modal-header">
       <button type="button" class="close" data-dismiss="modal">&times;</button>
     </div>
     <div class="modal-body">
       <div class="form-group">
         <a href="#" id="update_yes" class="btn btn-success text-center center-block">YES</a><br>
         <a href="#" id="update_no" class="btn btn-danger text-center center-block">NO</a><br>
         <a href="#" id="update_cancelled" class="btn btn-warning text-center center-block">CANCEL</a>
       </div>

     </div>
   </div>

 </div>

console.log( 'scheduled: ' + scheduled + ' orderid: ' + $('#userId').val() );

当按钮更新且页面刷新并注销会话时，我收到以下错误：

   <!-- Modal content-->
   <div class="modal-content" style="width: 300px; margin: 0 auto;">
     <div class="modal-header">
       <button type="button" class="close" data-dismiss="modal">&times;</button>
     </div>
     <div class="modal-body">
       <div class="form-group">
         <a href="#" id="update_yes" class="btn btn-success text-center center-block">YES</a><br>
         <a href="#" id="update_no" class="btn btn-danger text-center center-block">NO</a><br>
         <a href="#" id="update_cancelled" class="btn btn-warning text-center center-block">CANCEL</a>
       </div>

从您列出的内容来看，我认为您的php文件中可能有“session\u destroy（）”（虽然可能没有放在这里）。尝试对此进行注释，看看会话是否结束。希望它能帮助您：）。

我找不到ID为“scheduled”的HTML元素。你能告诉我它在哪里吗？而且，关于第一个问题，您在检查时是否在控制台中发现任何错误？scheduled用于数据目标和变量，在我的第一个问题中，我的控制台中没有错误。用户刚刚注销。否。当您说“#scheduled”时，意味着有一个ID为“scheduled”的HTML元素。你有这样的元素吗？…我的坏，忘了把它去掉，那个代码是多余的。更新了问题，让我们一起来。
