Question

Here is the div element on my page:

How can I change a class’s content?

So from existing which is: class=”jcarousel-next jcarousel-next-horizontal”

to class=”jcarousel-next jcarousel-next-horizontal jcarousel-next-
disabled jcarousel-next-disabled-horizontal”

Do I need to completely remove it by using removeClass and then re-add?

Answer 1

no you can just use addClass. if you add a class that is already there jQuery wont add it again

$('#myelem').addClass('jcarousel-next-disabled jcarousel-next-disabled-horizontal');
