replaceClass

[rudeboiidevil2k7@…]

jQuery should include a function that replace a class, for example if you wish to replace a class you could do it like this:

$('#element').replaceClass('classname', 'tothisclassname');

Instead of doing something like this:

Would be easier to have this feature, don't you think? :)

$('#element').removeClass('classname');
$('#element').addClass('tothisclassname');

You can actually use toggleClass in this fashion as shown here:  http://jsfiddle.net/mv6mB/

As mentioned above (and can be seen  here), toggleClass's syntax supports easily switching classes (or replacing as you refer to it) already. Unless there are use-cases which toggleClass would not be appropriate for, we'll be closing this feature/enhancement request as the behavior is already supported.

Also, jQueryUI's toggleClass adds animation support incase you're itching to make that feature request.
