Re: [jQuery] Form plugin revisited ;-)

> How does jQuery(':input', this) differ from > jQuery('input,textarea,select,button', this) ? Great question, Aaron, The ":input" selector will grab all elements and then filter them using a regex match of the nodeName against "input|select|textarea|button". On the other hand, the "input,textarea,select,button" selector will grab only those elements (using getElementsByTagName I believe) and it will grab them *in that order*. So the first expression guarantees us semantic ordering of the selected elements but is slower due to the regex matching. Mike

Re: [jQuery] Possible changes to hide/show

I totally agree that eventually it should be put in the core. I should have been more clear. I think it will be best as a 'plugin' for now to get all the kinks worked out. Keeping big changes like this as plugins will make it easier for people to test. I say big changes because I believe some of the issue lies in the way jQuery attempts to find the height and width of an element. The fx module depends on this quite heavily. I would also say that this change somewhat ties into seperating out the css logic from the attr method. I have actually been working on this part as well, making it a plugin for easier testing. I think there are several 'quick fixes' that could be applied but it would just clutter up the core and make it harder to maintain. I also used 'plugin' pretty loosely. In this case it is not a new method but rather just overwritting the current implemention of a few methods. However, perhaps this is not the best approach ... it was just my thought process. -- Brandon Aaron On 10/13/06, Blair McKenzie <shib71@xxxxxxxxx> wrote: > I tend to agree with John on this - smoothing away these bumps doesn't make > a lot of difference individually, but all that polish in combination has and > is making jQuery a pleasure to use. > > Blair > > > On 10/14/06, John Resig <jeresig@xxxxxxxxx> wrote: > > > Okay so ... after looking over the code in the 1.0.2 release (and > > > possibly earlier versions) work just fine with the plain ol' show and > > > hide methods.

Re: [jQuery] Possible changes to hide/show

After playin around with this some more ... I'm beginging to wonder if it is even possible to collapse a table row with .hide() and .show() from the fx module. I can't get a row height to be smaller than its conents unless I tell it to be display: block and then that really messes up the table in Firefox and Safari. I'm starting to think the best solution is to just short cut any table related elements to the plain .hide() and .show(). I haven't completely given up but everything I've tried thus far just isn't working ... or even close to working. -- Brandon Aaron On 10/13/06, Richard Thomas <lists@xxxxxxxxxxxx> wrote: > hide and show do not work properly on a table row within firefox, it > does however work in IE > > The reason being, firefox requires you use the "table-row" for the > display method instead of "block". > > > -- > Richard Thomas - CEO > Cyberlot Technologies Group Inc. > 507.398.4124 - Voice > > _______________________________________________ > jQuery mailing list > discuss@xxxxxxxxxx > http://jquery.com/discuss/ >
