您好，我正在尝试切换隐藏显示评论，我最初让它工作得很好，因为我将我的所有评论都放在一个带有 class 的 div 中.forum-comments。

但是，现在我将每个评论与具有.forum-comments类的 div 分开

这是原始代码：

   // Button dynamic comment show
    $("#forum").delegate(".btn-forum-comment-show", "click", function() {
      $(this).parent().next(".forum-comments").toggle();
      var change = $(this).parent().find(".btn-forum-comment-show").text();
      var show = '<i class="icon-plus-sign icon-white"></i> show';
      var hide = '<i class="icon-minus-sign icon-white"></i> hide';
      if(change == ' show')
      {
        $(this).parent().find(".btn-forum-comment-show").html(hide);
      }
      if(change == ' hide')
      {
        $(this).parent().find(".btn-forum-comment-show").html(show);
      }
    });

该功能停止工作，因为我对班级$(this).parent().next(".forum-comments").toggle();有每条评论。.forum-comments所以它只会打开和关闭第一条评论。其余的不受影响。如何更改此行为以便切换每个评论。？

      <pre class="forum-body">2nd comment1</pre>
      <div class="btn-group"><a class="btn btn-mini btn-danger btn-forum-comment-del-comment" id=""><i class="icon-remove-sign icon-white"></i> delete</a></div>
    </div>

默认情况下，这些评论是隐藏的，style="display:none"并且$.toggle()启用/禁用

这是整个部分的转储：

<div class="forum-post">
        <div><span class="forum-title">Welcome to the forum!</span><span class="forum-type label label-forum-Discussion">Discussion</span></div>

更新：解决了创建一个新的类.forum-comments和.forum-comment

var post = $(this).parents(".forum-comment");

和

$(this).parent().next(".forum-comments").toggle();

替换此行

$(this).parent().next(".forum-comments").toggle();

和

var $parent = $(this).parent();
$parent.next(".forum-comments").length ? $parent.next(".forum-comments").toggle()
                                       : $parent.prev(".forum-comments").toggle()

最后一个评论部分将不起作用，因为$parent.next(".forum-comments")它将评估为空选择器。所以在这种情况下它不起作用

尝试使用nextAll而不是next

$(this).parent().nextAll(".forum-comments").toggle();

检查文件
