在rails中 Rendering Partials through Ajax

之前做。net的时候,自己做了一个showcontent的插件,用来加载页面的局部partial

之前采用的是ashx的方式

但rails里面不太方面,今天找到一个比较好的方法,试验成功

起初网上找到一个解决方案

HTML Tab

<li class='StreamTab StreamTabRecent active'>
<%= link_to 'Most Recent', mostrecent_schools_path, :remote => true, :class => 'TabText' %>
</li>


<div id='ContentBody'>
<div id='ajax'></div>
<%= render 'users/microposts', :microposts => @microposts %>
</div>
School Controller

class SchoolsController < ApplicationController  
  def mostrecent
    @school = School.find_by_slug(request.url.gsub('http://localhost:3000/','')).id
    @microposts = @user.microposts.order('created_at DESC').paginate(:per_page => 3, :page => params[:page])
     respond_to do |format|
      format.html
      format.js
     end
  end
end

  

Most Recent JS

$("#ContentBody").html('<%= escape_javascript(render :partial => "users/microposts" )%>');

Routes

 resources :schools do collection do get :mostrecent end end

原文:http://stackoverflow.com/questions/17246411/ajax-call-to-render-partial-in-rails-3
但这个方法不太好,会有一些特殊字符过滤问题

后来发现这个方法不错

def mostrecent
  @school = School.find_by_slug(request.url.gsub('http://localhost:3000/','')).id
  @microposts = @user.microposts.order('created_at DESC').paginate(:per_page => 3, :page => params[:page])
  respond_to do |format|
    format.json { render :json => {:success => true, :html => (render_to_string 'users/microposts')} }
    format.html { }
  end
end

  

$('.TabText').live 'ajax:success', (event,data) ->
  $('#ContentBody').html(data.html) if(data.success == true)

  

通过locals可以给partial传直

render_to_string(:partial => 'my_partial', :layout => false, 
                 :locals => {:my_object => my_value})
 
 

利用这个方式可以做无刷新的分页技术,而且相当方便
