[jQuery] Form Handling
Another newbie question. I was looking at some cool form handling features of prototype (about half-way down this article: http://www.sitepoint.com/print/painless-_javascript_-prototype) and was trying to figure out jQuery has similar features. I'm a little confused I see the form plugin referenced from http://proj.jquery.com/plugins does some of what I'm looking for (such as serialize), but it also looks like some (maybe all?) of this functionality is already baked into the core jQuery library. Is this just simply not documented yet? Is there a good current overview of the latest built-in form handling features? 2 specific functions of prototype that I think look particularly useful are Form.Observer and Form.EventObserver. The former checks all form fields at a specified periodic interval and calls a specified callback if anything changes. The latter is similar only it listens for all relevant change events (onchange, onclick) of all form fields rather than polling at intervals. Does the core jQuery and/or an existing plugin have a similar feature? Sorry if I completely missed it - I dug around a bit and didn't find anything. Also, until the new site is launched, is proj.jquery.com the place to go (rather than jquery.com) for the most current info and documentation? Thanks!

Re: [jQuery] jQuery form handling
Hm, spiffy. If I wanted to get an element that didn't have an ID, I
should be able to do that with something like:
$('[EMAIL PROTECTED]myfield]').val();
Right? What about multi-value fields like select boxes or radio button sets?

jQuery has great ways to interact with forms built right in.
$('#formfieldID').val() gets the value
$('#formfieldID').val(someVar) sets the value
Those are just the two basics. There's loads more built in.

Hey folks. I'm evaluating jQuery for my company, and have a few questions
that I've not been able to find answers to in the Docs on the site yet.
The major question I have is about form handling. Specifically, does
jQuery (either core or a well-supported plugin) provide functions to
easily manage forms? By manage, I mean things like pulling values out,
setting or changing form values programmatically, attaching events in a
browser-independent way (Safari and events are vil, IME), validation
rules, etc. Compound form elements (date pickers, time pickers, drag-drop
ordering of elements in a multi-select box, etc.) are good, too.
Where does jQuery stand on these? I'm hoping well, but am not sure
presently. :-) Thanks.

Re: [jQuery] jQuery form handling
It was originally written the way you suggested but John rearranged them in svn v97. You'll have to ask him why. But I agree that pre/post is a more natural ordering. Wouldn't it make more sense if it was preCallback then postCallback - ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/
Re: [jQuery] jQuery form handling
I believe that would be this:
$('[EMAIL PROTECTED]myfield]')get[0].val();
Where 0 relates to the order of the items?

Nope, what he had was just fine - doing a .val() gets the value of the
first element matched.
