Hi there! Can anyone point me in the direction of some resources for building your own view helpers?

I want to acheive something simple:

In the view,

<%= button do %>   Delete <% end %>

will give

<div class='button'>   Delete </div>

in the source?

Can anybody help out? thanks

mmmh, I guess

def button   content_tag :div, :class => "button" end

will to the trick. but it is just because it is simple... If you have something complex, you hav to play with capture()

Another simple way, is to play with partials. you can use

def button   render :layout => '/shared/button' end

# app/view/shared/_button.html.erb <div class="button">   <%= yield %> </div>

hope it will help

Hey Gabriel - thanks for the advice.

Sorry for the late reply.

I've managed to get this working

  def delete_button_for(value, path, confirm=nil, id=nil)     content_tag :div,(link_to_remote value, {:url => path,       :method => :delete, :confirm => confirm}), :class => 'button', :id => id   end

:smiley:

Thanks again

Gavin
