It was the first thing I tried, using the same view and the following
script, but nothing happens in this case when the quantity changes. Maybe
it interferes with the 'add' and 'sub' callbacks?
<script>
jQuery(document).ready(function(){
jQuery('.e').change(function(){
jQuery('#910').slideToggle();
ajax("{{=URL(r=request,c='downld',f='order_reload')}}",[],'910');
jQuery('#910').slideToggle();
});
</script>
