在点击时渲染部分

我想对某些标准操作进行部分调用。 我正在使用此方法来调用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 

然后在我的部分，

 #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 

我怎么能有这样的东西：

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

所以我只在点击时渲染部分，而不是在页面加载时渲染？

Answer 1

你可以用javascript做到这一点：

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

然后，相应控制器中的操作将是：

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中创建delete_content.js.erb ，并在其中放置以下代码：

delete_content.js.erb

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

然后在你看来：

delete_content.html.erb

 
 #this div is html div that will render your partial  

不要忘记将部分_my_partial.html.erb放在同一个文件夹中。

Answer 2

要添加到接受的答案，我只是在将js部分更改为以下后才能使用它：

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

没有escape_javascript它只是在后台呈现部分而不是更新视图。

Answer 3

在视图上这样做：

 link_to "Delete #{item}", '/model/confirm_deletion', :method => :delete, :remote => true #add the class and extra attributes if neeeded 

在你的控制器上

 def confirm_deletion end 

并在js中添加一个视图到confirm_deletion动作

 #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 :javascript $(body).append($('#RevealDelete')); 

这将使ajax请求加载该自定义确认对话框，也许你想添加一些包装器来插入对话框而不是使用body.append
