Change Class Of Links With Default Values With Jquery

I have three links on which I manually set classes: One defaults to .active and the others default to .inactive. I have some jQuery that I'm using to toggle the class of the links

Solution 1:

If I do get you correct, your selector is too strict: handling only the inactive links.
Tried the following?

$(function(){
    var sidebar=$('#sidebar');
    sidebar.delegate('a', 'click',function(){
        sidebar.find('.active').toggleClass('active inactive');
        $(this).addClass('active').removeClass('inactive');
    });
});
