method

visual_effect

visual_effect(name, element_id = false, js_options = {})
public

Returns a JavaScript snippet to be used on the AJAX callbacks for starting visual effects.

This method requires the inclusion of the script.aculo.us JavaScript library.

Example: 

  <%= link_to_remote "Reload", :update => "posts",
        :url => { :action => "reload" },
        :complete => visual_effect(:highlight, "posts", :duration => 0.5 )

If no element_id is given, it assumes "element" which should be a local variable in the generated JavaScript execution context. This can be used for example with drop_receiving_element: 

  <%= drop_receving_element (...), :loading => visual_effect(:fade) %>

This would fade the element that was dropped on the drop receiving element.

You can change the behaviour with various options, see http://script.aculo.us for more documentation.
