我将Edit按钮添加到我的jQuery Datatable. 当用户单击此按钮时，该行变为可编辑的。更新的行应该保存到 MySQL DB，但问题来了 - 更新的行没有保存到 DB。Firebug 不显示任何错误消息。有人可以帮我解决问题吗？

<script type="text/javascript" charset="utf-8">
         $(document).ready(function(){
              $('#newspaper-b').dataTable({
              "sPaginationType":"full_numbers",
              "aaSorting":[[3, "asc"]],
              "bJQueryUI":true
              });
             $(".edit_but").click(function() {
              var ID=$(this).attr('id');
              $("#first_"+ID).hide();
              $("#last_"+ID).hide();
              $("#first_input_"+ID).show();
              $("#last_input_"+ID).show();
          });
             $(".edit_tr").change(function() {
                  var ID=$(this).attr('id');
                  var first=$("#first_input_"+ID).val();
                  var last=$("#last_input_"+ID).val();
                  var dataString = 'flightNum='+ ID +'&from='+first+'&STADate='+last;
                  $("#first_"+ID).html('<img src="load.gif" />'); // Loading image
                  if(first.length>0&& last.length>0) {
                  $.ajax({
                      type: "POST",
                      url: "callpage.php?page=tables/edit.php",
                      data: dataString,
                      cache: false,
                      success: function(html) {
                              $("#first_"+ID).html(first);
                              $("#last_"+ID).html(last);
                      }
                  });
                  } else
                  {
                    alert('All fields must be filled out.');
                  }
                });

尝试 $(".edit_tr input").change() 作为触发器。

更改事件仅限于输入、选择和文本区域，但您已尝试将其绑定到表格行。上面的代码会将其绑定到该类所在行内的任何输入。
