It then calls [...]

Last night’s jQuery Meetup was once again pretty awesome. Thanks again to BrightMix for hosting it and providing the Pizza and to Jonathan Sharp for making it all happen. Andrew from Blue Cross Blue Shield presented on AJAX. He showed us his concept of building a global jQuery handler using a Namespace. This would allow other programmers in [...]

I have a selection list, that once selected I would like to remove or disable the option choosen. However, at a later time I may want to add or enable it again. There is a bug in Internet Explorer that does not allow you to use the .hide() method on an option. It works just [...]
