CForms: immediate validation of input fields
Hello Cocooners!
I have a CFrom with many fields and other input elements. Validation (based
on the Cforms validation tags) happens when i submit the form. So far so
good. Now is it possible (and how) to have Cforms validate user inputs right
away after one field is filled out? So can I call the validation not only on
submit but also when the user focuses (clicks on) the next field on the
page? Maybe through the Javascript "onBlur" event handler?
Thank you in advance!

thank you guys! that helped a lot.
the <fi:styling onBlur="test();">
works fine too. thank you for that hint!
so i guess there can be a 3-level validation (used seperate OR together):
1- client-side via custom javascript through <fi:styling onBlur="xyz">
2- server-side both, the widget validation AND the fd:javascript stuff
3- application level in the database (or simular applications)
right?

Ofcoz multi-browser support isn't the easiest thing but it would already
be very handy if CForms automatically generates a js-structure with the
specification of each widget; for example:
aField = {required=true,datatype="datetime",format="dd/mm/yyyy"};
...
Then you've got all necessary data and metadata on the clientside and
everybody can produce it's own specific functions
(onblur,onchange,onclick,onsubmit,...) etc;

Re: CForms: immediate validation of input fields
I think that they were aiming to support more browsers by leaving most
actions on the server-side. Validation on server-side or client-side is,
in the end, a difference of opinion as you said. So you're right to
suggest a mechanism to choose between both. Like an attribute defining
"client-side" or "server-side" on each widget, and one default setting.
It's not there yet and I don't know if the developers are already
discussing/implementing this issue.

I think that they were aiming to support more browsers by leaving most
actions on the server-side. Validation on server-side or client-side is,
in the end, a difference of opinion as you said. So you're right to
suggest a mechanism to choose between both. Like an attribute defining
"client-side" or "server-side" on each widget, and one default setting.
It's not there yet and I don't know if the developers are already
discussing/implementing this issue.

CForms still doesn't have any clientside validations, which in my opinion
is currently a huge disadvantage coz now you have to declare the
specifications (datatype, required, format) in the form definition and
again in your own clientside javascript stuff. It would be perfect that
the CFormTemplateTransformer could automatically create those clientside
javascript pieces or at least give a javascript-structure with the
metadata of each field in it.

Re: CForms: immediate validation of input fields
If I am correct, all stuff happens server-side. The fd:javascript will
happen at the same moment as the other validations (meaning sever-side,
on-submit). If you really want to have a client-side validation, you
can try to set some extra stuff in your template:
<ft:widget id=" ... "><fi:styling onchange=""></ft:widget>
The fi:styling attributes that are not used by the cform stylesheets
will be copied into your html input element (ending up with <input ....
onchange=""/>). So you can set a javascript piece in which you validate
your field in those attributes.

Jan
