Re: [jQuery] Fast form serializer function for review
I don't think that's proper behavior, though. *Both* values of foo should be posted if both are present. So, you'd either get foo=offValue, or foo=offValue,onValue. Either way, your backend code shouldn't break if the submitted fields are in the wrong order. - Brian On 10/3/06, Mike Alsup [EMAIL PROTECTED] wrote: So I think this new serialize method is pretty damn good! Is there *anyone* out there that cares about the semantic ordering of the posted values? Personally, I do not, and I definitely would like to have only a single serialize method. Maybe the semantic version could be left as a separate plugin for anyone that needs that capability. I vote for updating the form plugin with this new version. Yes, I care. Case: An unchecked checkbox doesn't post. However, you usually want to work with an on/off value. I use this construct (stolen from Rails I think): input type=hidden name=foo value=offValue input type=checkbox name=foo value=onValue This way, when the checkbox is not checked, offValue is posted for foo.

Re: [jQuery] Full featured form validation library in jQuery?
That's a lot of stuff! Seriously, I think that what is being requested here, more than anything else, is organization. Can we start grouping our code into plugin packs, or something? One for forms and friends, one for all kinds of visual effects (perhaps a package that groups the best of the best visual plugins with Interface?), one for language extensions, and so on. It might even be a Good Thing to version them, and pack them to save space. There are a lot of really great plugins here, but they're not as easily accessible as they can be. For everyone else: All these plugins are done on a largely volunteer basis. This is an unfunded, we-do-this-because-we-love-it open source project. Generally, our response to I need ___ is Great! I can't wait to see how it looks after you've written it! So, don't expect anything huge to be done upon request. But, a lot of useful plugins are already rolling around here. So, don't despair. :) - Brian One thing I'd also like to request is a complete form widgets plugin. At the moment there are a plethora of form widgets, each of them single plugins. That's not very useful for someone that wants something that gets included once and called multiple times. Ideally, someone would come out with a forms plugin that includes basic validation and error display along with form widgets. ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/

Re: [jQuery] Chainable if/else - hot or not?
I'm not crazy about the .filter()/.$else() as presented for one reason: It calls .end() as part of its implementation. Most programmers will expect to have to call .end() themselves, and it will be a bit confusing if it doesn't have to be explicitly called in this case. In fact, I don't think that people will expect the object returned by .$else(), which is the result of the .not() in the implementation (that they didn't call explicitly). The object that .$else() returns should be the original object returned by .filter() . That ends up being the making the most sense, I think. Agree? - Brian Brandon Aaron schrieb: ** Going to re-read to make sure I'm not complete off-base ** Okay ... so after re-reading I think that Jörn's first idea is the better one than the other suggestions. My only concern is that it changes the behavior of the is method. I still think making this its own method is the best option. With that said I think either modifying the is method, not method or *preferably* adding a new method with this simple syntax will be very useful! The modification to is() won't break any existing code that uses is() as documented (with only one paramter).

I'm not sure I like that. If .filter() is destructive, it should be destructive all the time. It's less confusing that way. Just my opinion. :) that is cool, but destructive... is there a non-destructive if alternative available? Or do they just remove the filtered items from the chain, and let the rest of the chain calls deal with else cases?

Re: [jQuery] Single Value Attributes
What happens if you call .checked() with no args? Wouldn't that

Hey everyone -
I stumbled across a point of optimization today, all of the following
attributes (and probably more - let me know) can only have a single
value.
checked=checked
multiple=multiple
disabled=disabled
readonly=readonly
disabled=disabled
selected=selected
I'd like to add in methods like:
.checked( true | false )
Which does this in the background (but for each attribute):
$.fn.checked = function(b) {
if ( b )
this.attr( checked, checked );
else
this.removeAttr( checked );
};
What do you think?

Re: [jQuery] unchange() - how does it work?
The event code only deals with unobtrusive events. If you have an
inline event in the tag, you need to use the attr() method to overwrite
the onchange attribute with a blank string. It sounds dumb, and... it
is. But, it works.
$( #myradiobutton ).attr( onchange, ).change( function() { ... } );
You can throw in unchange() anyway, for good measure, in case there may be
events registered the not-inline way as well.
This brings up an interesting question. Should unevent simply deal with
this case? I think that adding .attr( onevent, ) to each unevent
would help enforce the Principle of Least Surprise.
- Brian
I have a number of controls on a form that have a default onchange()
function. In some places I would like to change the onchange function to

Re: [jQuery] jQuery Projects
Here's an idea: label for=foo class=validate 000h000h00/label input name=foo id=foo type=text / It's HTML 4.01, will probably pass for strict, and it semantically separates the validation from the field. The idea is that for every label with class validate, there's a validation mask somewhere within the classes that should be applied to the associated field. This can conceivably apply to any input, if you want to do the work. This could guarantee a set number of checkboxes are checked, one of the radio buttons has been chosen, a select is not left on its default value, etc. Some gotchas: * The only legal place to put the mask would be as a class. It would be a Bad Thing if you tried to make it the ID, since each element should have only one unique ID, and you may want to apply the same mask to a different field. The bonus here is that you can also style by validation mask. How cool would that be? (e.g.: Use a background-image of a phone icon for fields that want a phone number.) * One would need to create a language for expressing a mask using only alphanumerics and underscores, since that's what's legal in a class. This, in turn, may require enough regexp magic to make the best of us go running for the aspirin bottle. :) * One would need to support two legal HTML syntax cases - label for=foo and labelinput //label . * For broken use cases (e.g.: class=validate -- no mask is provided), one would want to bail out silently rather than throwing an error. What do you think? I'm almost feeling crazy enough to take a whack at it. It all starts with $(label), how hard could it be? :) - Brian And the using it like this: input validate=pattern:###-###-## / And I still vote for doing in a standards compliant way... -- Klaus ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/ ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/
Re: [jQuery] jQuery Projects
I don't think that, technically, things like parens and colons are permitted in a class.

Re: [jQuery] jQuery Projects
After checking the W3C spec, it doesn't say much about what is and isn't
legal in a class in HTML. It simply says that it's a CDATA. But, the
examples in the spec doc do allow hyphens. I'd be cautious about what
characters I use in a class, because CSS is stricter about what may be in
a selector than HTML itself is, and it would be a Good Thing to be able to
style by validation mask.
From the CSS spec:
***
In CSS 2.1, identifiers (including element names, classes, and IDs in
selectors) can contain only the characters [A-Za-z0-9] and ISO 10646
characters U+00A1 and higher, plus the hyphen (-) and the underscore (_);
they cannot start with a digit, or a hyphen followed by a digit. Only
properties, values, units, pseudo-classes, pseudo-elements, and at-rules
may start with a hyphen (-); other identifiers (e.g. element names,
classes, or IDs) may not. Identifiers can also contain escaped characters
and any ISO 10646 character as a numeric code (see next item). For
instance, the identifier BW? may be written as B\W\? or B\26 W\3F.

I've never had problems with parenthesis and colons in the classname.
They are just ignore by the css parser. Quick test:
style type=text/css
.bold {
font-weight: bold;
}
.underline {
text-decoration: underline;
}
/style
span class=bold $(something:12) underlineSome text/span
Not sure how this will impact on the use of addClass and removeClass
using jQuery though.
As an alternative, you can still do it standards-compliant (or write
an
XHTML module):
input class=$v(pattern:###-###-##) /
The plugin checks the class if there is no validate attribute.

The validation plugin uses $v(...) as a default to hide validation rules
from stylesheets. But as you can override that via an option, that would
be no problem either. Just setup the validation options like this:
var options = {
rulesClassStart: ,
rulesClassEnd: ,
rulesDelimiter: ,
// other options
};
That would allow you to define your validation like this:
input class=required pattern:###-###-## /
Obviously, it wouldn't allow you to use 'pattern' as a style class. In
that case, you should just seperate styles and validations.
Well, it looks like Joern more or less has it covered. I'd simply use
something like { rulesClassStart: val-, rulesClassEnd: ;
rulesDelimiter: }.
He also mentions (in another email) that using label to semantically
separate the validations from the inputs can be done with relatively small
modifications to his existing plugin. Worth looking into.

Re: [jQuery] jQuery Projects
I think that people are going to want more flexibility in terms of what they want to validate. It would be great to include very common shortcuts, like us-phone-number, credit-card-number, or email-address. But, we can't predict what everyone's data will look like. There must be a way to provide custom formats. - Brian What about when you want to change some aspect of the mask? Say, the phone number mask now needs to handle international numbers as well. Why not separate the mask from the class name like this: label for=foo class=validate phoneNum/label input name=foo id=foo type=text / And put the mask in the jQuery code? -- Tim ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/
Re: [jQuery] Form plugin's serialize(): performance issues
Perhaps there should be a FastSerialize method, that doesn't guarantee semantic order, and uses every shortcut to cut down on dom-walking time? This way, the developer can choose whether to use the faster method, or the slower-but-correctly-ordered method. - Brian Can you explain why processing elements in semantic order is important? Two reasons: $(input | select).eq(0) This should access the first matched element of input or select - when the order isn't important, you'll never know which element will actually be first. It's important that the element is actually the first element in the document. Secondly, when serializing forms, the order of the elements that comes back is frequently important - having a different order can cause problems for certain applications. --John ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/ ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/
