Good afternoon to you all,
I have an order form where people can check the fruits they want and
select the price of each fruit that they have checked.
When I click the checkbox now, it does not seem to affect the
corresponding price dropdown. What am I doing wrong?
Here''s the javascript:
<script type="text/javascript">
function toggle_fruit_price(lqname) {
$(lqname).disabled = (!$(lqname).disabled);
}
</script>
Then, inside my loop of @fruits:
<%= fruit.name %>
<%= check_box_tag fruit.name, 1, false, :onchange =>
"toggle_fruit_price(#{fruit.name}_price);" %>
<%= select_tag("#{fruit.name}_price", options_for_select((0..100)))
%>
Does anyone see what I''m doing wrong? Any help is appreciated.
