我需要一个小功能来显示一个盒子设计来写回复评论

我找了一些 examples (by jsfiddle)或 jsfiddle ，但问题不仅仅是显示响应字段，您还应该通过单击答案图标获取帖子的 ID

然后能够评论并通过ajax发送评论

我的想法:

Answer 1

我会这样做:

1. 给UL#comments-list中的每一个LI添加data-comment_id属性，这样我们就知道是哪条评论了被回复。我还在 class 属性中添加了 comment:

   <li class="comment" data-comment_id="1">
   

2. 在上面的 LI 中的 div.comment-content 之后添加“回复”按钮/链接:

   <button type="button" class="comment-reply-link">Reply</button>
   

3. 使用单个评论回复表单并将其放在评论容器之后(即 div.comments-container):

   <div id="comment-reply">
     <h3>Leave a Reply</h3>
     <form method="post" action="">
       <input type="hidden" class="post-id" value="123">
       <div class="form-field">
         <input class="comment-name" placeholder="Name">
       </div>
       <div class="form-field">
         <textarea class="comment-content" rows="3" placeholder="Message"></textarea>
       </div>
       <button type="button" class="submit">Post Comment</button>
       <button type="button" class="cancel">Cancel Reply</button>
     </form>
   </div>
   

   如果你看到上面的标记，我将帖子 ID 放在一个隐藏的 input 中，带有 class post-id。

现在是 JavaScript 部分..

1. 移动评论回复表单(到适当的评论包装器):

   $(document).on('click', '.comment-reply-link', function(e){
     e.preventDefault();
   
     // Show the previously clicked button.
     $('#comment-reply').closest('.comment')
       .find('.comment-reply-link').show();
   
     // Hide the button.
     $(this).hide();
   
     // Move the comment reply form wrapper.
     $('#comment-reply').insertAfter(this)
       .find('.comment-name').focus()                // focus on the Name field
       .end().find('.cancel').removeClass('hidden'); // show the cancel button
   });
   

2. 取消评论回复:

   $('#comment-reply').on('click', '.cancel', function(e){
     e.preventDefault();
     this.blur();
   
     // Show the previously clicked button.
     $(this).closest('.comment')
       .find('.comment-reply-link').show();
   
     // Place the comment reply form back to its initial position.
     $('#comment-reply')
       .find('.cancel').addClass('hidden')        // show the cancel button
       .end().insertAfter('.comments-container'); // and then move the form
   });
   

3. 点击“发表评论”按钮时:

   $('#comment-reply').on('click', '.submit', function(e){
     e.preventDefault();
   
     const $comment = $(this).closest('.comment');
   
     // Get the post and comment IDs.
     const comment_id = $comment.data('comment_id');
     const post_id = $('#comment-reply').find('.post-id').val();
     console.log(post_id, comment_id);
   
     // Here you can make your AJAX call...
   });

但是...进一步改进样式(即 CSS 代码)取决于您。
