我无法再渲染的部分通过Ajax请求。我可以通过js文件目前正在通过其他的东西，如警报（），甚至改变当前DIV的HTML。但是，当我试图使部分（等级，在这种情况下），什么都不会刷新。谐音做工精细，因为它们呈现在分页和负载感，但不是在我单击upvote或downvote。我使用嵌套的谐音，使其首先渲染_tracks，然后_rating。这是我have..what我缺少什么？

vote.js.erb

  $（等级）HTML（＆LT;％= escape_javascript（渲染（：部分=＆GT;'评级'））％＆gt;中）
 

有了这个，我也是这些，没有成功。

  $（等级）HTML（＆LT;％= escape_javascript（渲染（等级））％＆gt;中）
   $（等级）HTML（＆LT;％= escape_javascript（渲染（：部分=＆gt;中等级，：当地人=＆GT; {：轨道=＆GT;轨道}））％＆gt;中）
 

这，在另一方面，没有工作：

  $（等级）HTML（＆LT;％= escape_javascript（测试文本在这里）％＆gt;中）
 

_tracks.html.erb

 ＆LT;％的轨道@tracks％GT;
            ＆LT; D​​IV CLASS =span4＆GT;
                ＆LT; D​​IV CLASS =跟踪＆GT;
                    ＆LT; D​​IV CLASS =评级＆GT;
                        ＆LT;％=渲染：部分=＆GT; 评级，：当地人=＆GT; {：轨道=＆GT;轨道}％GT;
                    ＆LT; / DIV＆GT;

                    ＆所述; A HREF =＆其中;％= track.youtube_link％＆gt;中＆GT;＆所述; / a取代;

                    ＆LT;如果current_user.admin％？ ％＆GT;

                        ＆LT;％=的link_to编辑，edit_track_path（轨道）％＆GT;
                    ＆LT;％结束％GT;
                ＆LT; / DIV＆GT;
            ＆LT; / DIV＆GT;
＆LT;％结束％GT;
 

_rating.html.erb

 ＆LT;％VT = track.votetype（CURRENT_USER）％＆GT;

                ＆LT;％如果VT =向上％GT！;
                    ＆LT;％=的link_to image_tag（up_arrow.png，ALT：Upvote），vote_path（轨道，：类型=＆gt;中达），：远程=＆GT;真％＆GT;
                ＆LT;％ELSIF％GT;
                    ＆LT;％=向上％GT;
                ＆LT;％结束％GT;

                ＆其中;％= track.rating％GT;

                ＆LT;％！如果VT =下％＆GT;
                    ＆LT;％=的link_to image_tag（down_arrow.png，ALT：Downvote），vote_path（轨道，：类型=＆gt;中下），：远程=＆GT;真％＆GT;
                ＆LT;％ELSIF％GT;
                    ＆LT;％=下降％＆GT;
                ＆LT;％结束％GT;
 

跟踪控制器

  @ vote.update_attributes（：vote_type =＆GT; PARAMS [：类型]）
        如果@ vote.save
      respond_to代码做|格式|
        的format.html {redirect_to时：回}
        format.js
      结束
 

解决方案

  $（等级）HTML（＆LT;％= escape_javascript（渲染（：部分=＆GT; 评级，：当地人=＆GT; {：轨道=＆GT;轨道}））％＆gt;中）
 

必须是

  $（等级）HTML（＆LT;％= escape_javascript（渲染（：部分=＆gt;中等级，：当地人=＆GT; {：轨道=＆GT ; @track}））％＆gt;中）
 

@符号通过变量，不同的是循环在previous部分，你并不需要它。现在工作的罚款。

I am having trouble re-rendering a partial through an Ajax request. I can currently pass other things through the js file such as alert() and even changing the html in the current div. But when I try and render the partial (rating, in this instance), nothing will refresh. The partials work fine in the sense that they render on pagination and on load, but not after I click an upvote or downvote. I'm using nested partials so that it renders _tracks first, then _rating. Here's what I have..what am I missing?

vote.js.erb

$(".rating").html("<%= escape_javascript(render(:partial => 'rating')) %>")

With this I also these, with no success.

   $(".rating").html("<%= escape_javascript(render("rating")) %>")
   $(".rating").html("<%= escape_javascript( render( :partial => "rating", :locals => { :track => track }) ) %>")

This, on the other hand, does work:

$(".rating").html("<%= escape_javascript("test text here) %>")

_tracks.html.erb

    <% for track in @tracks %>
            <div class="span4">
                <div class="track">
                    <div class="rating">
                        <%= render :partial => "rating", :locals => { :track => track } %>
                    </div>

                    <a href="<%= track.youtube_link %>"></a>

                    <% if current_user.admin? %> 
                        <%= link_to "delete", track, method: :delete, confirm: "You sure?" %>
                        <%= link_to "edit", edit_track_path(track) %>
                    <% end %>
                </div>
            </div>
<% end %>

_rating.html.erb

<% vt = track.votetype(current_user) %>

                <% if vt != "up" %>
                    <%= link_to image_tag("up_arrow.png", alt: "Upvote"), vote_path(track, :type => "up"), :remote => true %>
                <% elsif %>
                    <%= "up" %>
                <% end %>

                <%= track.rating %>

                <% if vt != "down" %>
                    <%= link_to image_tag("down_arrow.png", alt: "Downvote"), vote_path(track, :type => "down"), :remote => true %>
                <% elsif %>
                    <%= "down" %>
                <% end %>

track controller

@vote.update_attributes(:vote_type => params[:type])
        if @vote.save
      respond_to do |format|
        format.html {redirect_to :back}
        format.js
      end

$(".rating").html("<%= escape_javascript( render( :partial => "rating", :locals => { :track => track }) ) %>")

needs to be

$(".rating").html("<%= escape_javascript( render( :partial => "rating", :locals => { :track => @track }) ) %>")

The @ symbol passes the variable through, unlike the for loop in the previous partial where you didn't need it. Working fine now.
