So let's say I have:
<% form_for :skus do |f|%>
Product: <%= f.text_field :name, :autocomplete => "off", %>
<%= submit_tag "Get Product" %>
<% end -%>
then how should I do the prototype observe code? I tried and no alert
fired:
<script type="text/javascript">
$('sku_name').observe('click', function(event){
alert(Event.element(event).innerHTML);
});
</script>
