我想要做的是一些如何仅将下面的 jquery 函数应用于刚刚发布的评论的类。相反,该功能被应用于所有类。
这是我目前正在使用的代码:
控制器:
class CommentsController < ApplicationController
def create
@comment = Micropost.find(params[:comment][:micropost_id]).comments.build(params[:comment])
respond_to do |format|
if @comment.save
unless params[:comment][:recipient].blank? # this will be blank when current user is commenting/replying on their own wall
recipient = User.find(params[:comment][:recipient])
UserMailer.new_wall_post_comment_notification(recipient, current_user).deliver if recipient.email_notification == 1
end
format.js { render :post_comment }
else
format.js { render :form_errors }
end
end
end
end
jQuery:
$.ajax({
success: function(){
$('.post_container').append('test <br />');
}
});
<% sleep 1 %>
它类似于我用于单个主微帖子表单的代码,但是有几个使用相同类的评论,因此测试将应用于所有 post_containers 而不是刚刚发布帖子的那个。“测试”文本最终将替换为包含用户发布的实际评论的 div。
通常我会使用“this”,但这在这里不起作用。
HTML:
<div class="post_content">
<div class="post_container">
<div class="userNameFontStyle">
<%= link_to current_users_username.capitalize, current_users_username %> -
<div class="post_time">
<%= time_ago_in_words(m.created_at) %> ago.
</div>
</div>
<%= simple_format h(m.content) %>
</div>
<% if m.comments.any? %>
<% comments(m.id).each do |comment| %>
<div class="comment_container">
<%= link_to image_tag(default_photo_for_commenter(comment), :class => "commenter_photo"), commenter(comment.user_id).username %>
<div class="commenter_content">
<div class="userNameFontStyle">
<%= link_to commenter(comment.user_id).username.capitalize, commenter(comment.user_id).username %> - <%= simple_format h(comment.content) %>
</div>
</div>
<div class="comment_post_time">
<%= time_ago_in_words(comment.created_at) %> ago.
</div>
</div>
<% end %>
<% end %>
<% if logged_in? %>
<%= form_for @comment, :remote => true do |f| %>
<%= f.hidden_field :user_id, :value => current_user.id %>
<%= f.hidden_field :micropost_id, :value => m.id %>
<%= f.text_area :content, :placeholder => 'Post a comment...', :class => "comment_box", :rows => 0, :columns => 0 %>
<div class="commentButtons">
<%= f.submit 'Post it', :class => "commentButton" %>
<div class="cancelButton">
Cancel
</div>
</div>
<% end %>
<% end %>
</div>
</div>
我将如何处理?
亲切的问候
