The web2py book uses the following example to demonstrate how to call the ajax
function in the views page.
*Controller*:
def one():
return dict()
def echo():
return request.vars.name
*Views:*
{{extend 'layout.html'}}
<form>
<input name="name" onkeyup="ajax('echo', ['name'], 'target')" />
</form>
<div id="target"></div>
However,I would like to know what modifications to above code would need to be
made in order for the ajax function to work with the built in
forms function, instead of writing out the html input fields?
So for example, I have the following code below.
Model:
db.define_table('product',
Field('quantity', 'integer'),
Field('price', 'integer'))
Controller:
def product_form():
form = SQLFORM(db.product)
if form.process().accepted:
session.flash = 'form accepted'
redirect(URL('next_page'))
return dict(form=form)
def total_cost():
price = request.vars.price
quantity = request.vars.quantity
total = int(price) * int(quantity)
return total
Views:
{=form}
How can I modify the code below with the code I have above?
*{{extend 'layout.html'}}
<form>
<input name="name" onkeyup="ajax('echo', ['name'], 'target')" />
</form>
<div id="target"></div>*
