我正在尝试使用 Jquery 在单击按钮时编辑引导表的值。我参考了这篇文章making row editable 它工作得很好。我唯一的问题是双击按钮进入编辑模式。这是我的代码 sn-p

$('.editbtn').click(function () {
              var currentTD = $(this).parents('tr').find('td');
              if ($(this).html() == 'Edit') {
                  currentTD = $(this).parents('tr').find($("td").not(":nth-child(1)"));
                  $.each(currentTD, function () {
                      $(this).prop('contenteditable', true).css({
                        'background':'#fff',
                        'color':'#000'

                    })
                  });
              } else {
                 $.each(currentTD, function () {
                      $(this).prop('contenteditable', false).removeAttr("style");
                  });
              }
    
              $(this).html($(this).html() == 'Edit' ? 'Save' : 'Edit')
              if ($(this).html() == 'Save'){
                $(this).prop('contenteditable',false)
              }
    
          });

                    <button type="button" class="btn btn-danger">

               <tr>
                  <td>21st August</td>
                  <td>abc</td>
         
                    <td  contenteditable="false"><button type="button" class="btn btn-primary editbtn" >
                     Edit

                    Delete
                     </button></td>
               </tr>  <tr>
                  <td>21st August</td>
                  <td>abc</td>
              

                  <td  contenteditable="false"><button type="button" class="btn btn-primary editbtn">
                     Edit
                     </button>
                    <button type="button" class="btn btn-danger">
                    Delete
                     </button></td>
               </tr>
            </tbody>
    </table>

这里我禁用了编辑一列中的数据。如您所见，当我们单击第一行中的编辑按钮时，只需单击一次，但对于其余行，则需要多次单击。多次单击后，它会在单击编辑模式，直到刷新页面。我不知道我错过了哪里。我会感谢你的帮助。

【解决方案1】：

问题在于这一行：它考虑了 line，而您却考虑了 $(this).html()。

<button type="button" class="btn btn-primary editbtn" >
                     Edit
                     </button>

为什么它在下次点击时起作用，因为在您的代码中您更改为 Edit

$(this).html($(this).html() == 'Edit' ? 'Save' : 'Edit')

您可以尝试以下操作：

使用$(this).text().trim() 或更正该行：

<button type="button" class="btn btn-primary editbtn" >Edit</button>
