## code

<%= link_to_function "Show or Hide Nutritional Information", visual_effect(:toggle_blind, "nutritional_#{food.id}", :duration => 1) %>
        <div id="nutritional_<%=h food.id %>">


## result

<a href="#" onclick="Effect.toggle("nutritional_12",'blind',{duration:1});; return false;">Show or Hide Nutritional Information</a>
	<div id="nutritional_12">

## source

complete guess but I'm thinking it might have something to do with

:onclick => (html_options[:onclick] ? "#{html_options[:onclick]}; " : "") + "#{function}; return false;"


that line of code from the api source. does #{function} escape the input thereby turning "nutritional_1" into "nutritional_1" ?
