Hi chich,
As everyone has mentioned, you will need unique IDs for your HTML
elements. Fortunately, Rails 2.0 has a helper method that will
generate unique IDs for elements given an ActiveRecord object. div_for
is very easy to use:
<% trainees.each do |trainee| %>
<% div_for trainee do %>
<%= link_to_function h(trainee.name),
"my_javascript_function(#{trainee.id})", :class => 'LINKSON' %>
<% end %>
<% end %>
...
<script type="text/javascript">
function my_javascript_function(id) {
$("trainee_" + id).class = "LINKSOFF";
}
</script>
So, say you have a trainee record with ID 8, then div_for(trainee)
would generate:
<div id="trainee_8"></div>
Hope this helps.
