单击时呈现局部 [英] render partial on click

问题描述

我想在一些标准操作上调用局部函数.我正在使用这种方法来调用局部的:

I would like to call partials on some standard operations. I am using this method for calling the partial:

 %li= link_to 'Delete Event', 'javascript:void(0);', :class => 'alert tiny button', :data => {'reveal-id' => :RevealDelete}
= render 'layouts/reveal_delete', :item => event_display(@event.event), :resource => @event

然后在我的局部

#RevealDelete.reveal-modal


 %a.close-reveal-modal ×
  %h3= "Delete #{item}"
  %p Are you sure you want to delete this?
  =link_to "Delete #{item}", resource, :method => :delete, :remote => :true, :confirm => resource, :class => 'button close-reveal-modal'
  %a.button.alert.close-reveal-modal Cancel

我怎么能拥有这样的东西?

How can I have this has as something like:

link_to 'Delete', '#', :partial => 'layouts/delete', :remote => :true? 

这样我只在单击时渲染该部分，而在页面加载时不渲染?

so that I only render that partial when clicked and not when the page loads?

推荐答案

您可以使用javascript这样的代码:

You can do that with javascript like:

<%= link_to "Delete", delete_content_path, :remote => true %>

相应控制器中的操作将是这样:

The action in your corresponding controller then will be this:

我的控制器:

def delete_content
  respond_to do |format|               
    format.js
  end        
end 

然后，您可以在链接的正确目录内创建delete_content.js.erb，并在其中放置以下代码:

Then you can create the delete_content.js.erb inside your correct directory of the link and there you put the following code:

delete_content.js.erb

$('#div_id').html("<%= render :partial => 'my_partial' %>");

然后在您看来:

delete_content.html.erb

<div id = "div_id">
#this div is html div that will render your partial

</div>

请不要忘记将部分 _my_partial.html.erb 放在同一文件夹中.

Don't forget to put your partial _my_partial.html.erb in the same folder.
