原标题:Render own partial via javascript in Rails

Say有一部分人叫——hello_world.html.erb。

<% if toggle %>
    HELLO WORLD ON
    <%= link_to "Turn it off", what_should_come_here %>
<% else %>
    HELLO WORLD OFF
    <%= link_to "Turn it on", what_should_come_here %>
<% end %>

部分内容将按此等指数存档。

<%= render :partial =>  test/hello_world , :locals => {:toggle => true} %>

但是,在我点击了“角逐”链路后,它应当从奥恩和拉普邦之间转开,这基本上会使自己部分地再次凌驾于先前的部分。 如何做到这一点?

注:我在http://sscce.org/格式中给出了这个问题。

最佳回答

最好使用<条码>链接_to_remote<>条码>。

index.html.erb

<div id="toggle_div">
  <%= render :partial =>  test/hello_world , :locals => {:toggle => @toggle} %>
</div>

_hello_world.html.erb

<% if toggle %>
    HELLO WORLD ON
    <%= link_to_remote "Turn it off", my_action_path(:toggle => toggle) %>
<% else %>
    HELLO WORLD OFF
    <%= link_to_remote "Turn it on", my_action_path(:toggle => toggle) %>
<% end %>

<>>在行动上>

def myaction
   value = params[:toggle]
   // do something with toggle value

   @toggle = value == "true" ? false: true
   render :update do |page|
     page.replace_html  toggle_div , :partial =>  hello_world , :locals => {:toggle => @toggle}
   end
end
