How to override a class using jquery

Question

A jQuery CSS class sets the following:

 .newwidget { border: 1px solid #5a9ee9; background: #5a9ee9 url(t6.gif) 50% 50% repeat-x; color: #ffffff; font-weight: bold; text-transform: uppercase; padding:3px 3px 3px 10px; font-size:10px}

How can this class be overridden and a new class added so that I can put different styles in it? Maybe I have to remove before classes before adding them. How is this done?

Thanks

Answer 1

Use the class selector with addClass and removeClass.

$('.newwidget').removeClass('newwidget').addClass('newerwidget');

Answer 2

I think it's worth noting that you can remove all the classes by leaving off the parameter from removeClass():

$('.newwidget').removeClass().addClass('newerwidget');
