I have a simple show/hide function for a div as follows :
<%= link_to_function "Show|Hide",
visual_effect(:toggle_slide, :images, :duration => 1, :queue =>
''end'') %>
I''d like to just display Hide, then when the link is clicked perform
the
toggle_slide and then change the link text to ''Show'' (and back
when
clicked again).
I''d like to do something like :
<%= link_to_function "Hide", update_page{|page|
page.visual_effect(:toggle_slide, :images, :duration => 1, :queue =>
''end'')
if page.select(''toggle_images'') ==
''Hide''
page.select(''toggle_images'').replace_html(:text =>
''Show'')
else
page.select(''toggle_images'').replace_html(:text =>
''Hide'')
end
},
{ :id => ''toggle_images''} %>
However you can''t use Ruby within the block like this (as far as I can
tell). I could use an Ajax call to a partial to do the replace but this
seems overkill.
Does anybody have a solution for this example that doesn''t involve
custom JS or an Ajax call ?

Re: Conditional Protoypte updates - Is there a simple answer ?
I think this code is just screaming for an RJS template. Change your link_to_function to a link_to_remote and name your action after your RJS template name. Don''t define a method for this in your controller and Rails will magically find your RJS template. All of your page.* code should go into the RJS template just fine. Read about RJS stuff here: http://rubynoob.com/articles/2006/05/13/simple-rails-rjs-tutorial And here''s a list to lots of stuff: http://www.rubyinside.com/16-rjs-resources-and-tutorials-for-rails-programmers-5.html Hope that helps!

Re: Conditional Protoypte updates - Is there a simple answer ?
You might want to take a look at the UJS plugin. http://www.ujs4rails.com/ This seems like the kind of thing you want. It''s all ruby, with no javascript anywhere. And can be DRY too if used well. Have a <a href="#" id="toggle">Hide</a>, and your RJS-ish code inside an apply_behavior.

But that means I need to do a remote call to a server to replace some innerHTML for a DOM element for an already known value - not very efficient really ... -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
