Question

为什么这不会加载部分？（聊天评论DOM）但它会加载网址/评论。

如何只加载部分？我在这里缺少什么？

的routes.rb

.
.
.
resources :comments
get ":lang/v/:site/:uid/refresh_part_after_comment" => 'movies#refresh_part_after_comment'
get ':lang/v/:site/:uid' => 'movies#show', :via => :get, :as => :watch_v
resources :movies
.
.
.

views / movies / show.html.erb（此处输入表单！）

.
.
.
<div id="chat_comment">
    <%= render 'movies/comment' %>
</div>

<form action="/comments" method="post" data-remote="true" >
    <input type="text" name="body" size="50" id="body_input"/>
    <input type="hidden" name="elapsed_time" id="elapsed_time">
    <input type="hidden" name="video_id" value="<%= params[:uid] %>">
    <button type="submit" >Submit</button>
</form>

comments_controllr.rb

            @user.twitter_id = session[:id]
            @user.save

视图/电影/ refresh_part_after_comment.js.erb

$('#chat_comment').html("<%= j(render(:partial => 'movies/comment')) %>");

视图/电影/ _comment.html.erb

如果我理解你，你想在创建评论后显示views/movies/refresh_part_after_comment吗？

render中的CommentsController#create来电似乎没有意义，因为您使用的是网址作为参数：

render 'en/v/yt/' + @movie.uid + '/refresh_part_after_comment'

我认为你需要重定向到新创建的评论。与上面相同的URL应该有效：

redirect_to 'en/v/yt/' + @movie.uid + '/refresh_part_after_comment'

为什么在使用ajax加载时不会加载部分？
