Migrating plugins from Redmine 1.x to 2.x - Javascript does not work

Question

Sorry about my English. I have migrated plugins to Redmine 2.x, but Javascript functions does not work. At the top of one of my plugins show.html.erb:

<% content_for :javascript_includes do %>
<%= javascript_include_tag 'hgp_markers.js', :plugin => 'hgp_markers' %>
<% end %>

hgp_markers.js:

function hideEditableMarkers() {
  $$('.edit_marker').each(function(el) {
    el.hide();
    });
  $$('.show_marker').each(function(el) {
    el.show();
    });
}

Event.observe(window, 'load', hideEditableMarkers);

And this line with javascript:

<%= link_to_function l(:button_edit), "hideEditableMarkers(); $('marker_#{m.id}_row').hide(); $('marker_#{m.id}_row_edit').show(); return false;", :class => 'icon icon-edit' %>

What am I doing wrong? thanks in advance

Redmine 2.x (Rails 3.x) switches from Prototype to jQuery. So you need to migrate too.

Thus, Event.observe is a Prototype function.
