thank you so much for your detail explaination anthony.
i've spent more time following your advice to learn about javascript/jquery
and python through update my code but still not work (no error occured, but
what i'm expected is not realize). the basic logic is when user click the
button it will increase the quantity and update the total price (total =
price per unit * quantity), i know there is some mistake in my code, but i
don't know where. do you have any idea about this?
here is my updated code :
*controller : default.py*
def order_callback():
id=int(request.vars.id)
if request.vars.action=='add':
session.order[id]=session.order.get(id, 0)+1
if request.vars.action=='subtract':
session.order[id]=max(0,session.order.get(id, 0)-1)
return str(session.order[id])
def order_reload():
qty=int(request.vars.qty)
price=int(request.vars.price)
total=qty*price
return dict(total=total)
*view : order.html*
<table width="100%">
{{for id, qty in order.items():}}
{{p=db.product(id)}}
<tr>
<td>{{=SPAN(p.product_name)}}</td>
<td>{{=SPAN('Rp. %s' % p.unit_price)}}</td>
<td>{{=SPAN(qty, _id='item_%s' % p.id)}}</td>
<td>{{=SPAN(qty*p.unit_price, _id='total_%s' % p.id)}}</td>
<td>{{=SPAN(A('Add', callback=URL('order_callback',
vars=dict(id=p.id, action='add')), target='item_%s' % p.id, _title='Add
Quantity', _class='btn btn-navbar'))}} {{=SPAN(A('Subtract',
callback=URL('order_callback', vars=dict(id=p.id, action='subtract')),
target='item_%s' % p.id, _title='Substract Quantity', _class='btn
btn-navbar'))}}</td>
</tr>
<script>
jQuery(document).ready(function(){
jQuery('#item_{{=p.id}}').change(function(){
ajax('{{=URL('order_reload', vars=dict(qty=qty,
price=p.unit_price))}}', '', 'total_{{=p.id}}'));
});
</script>
{{pass}}
</table>
