Add and remove a class on click using jQuery?

Question

Please see this fiddle.

I am trying to add and remove a class on li elements that are clicked. It is a menu and when one clicks on each li item I want it to gain the class and all other li items have the class removed. So only one li item has the class at a time. This is how far I have got (see fiddle). I am not sure how to make the 'about-link' start with the class current, but then it is remove when one of the other li items are clicked on?

$('#about-link').addClass('current');
$('#menu li').on('click', function() {
    $(this).addClass('current').siblings().removeClass('current');
});

Solution 1

Why not try something like this?

$('#menu li a').on('click', function(){
    $('#menu li a.current').removeClass('current');
    $(this).addClass('current');
});

Solution 2

you can try this along, it may help to give a shorter code on large function.

$('#menu li a').on('click', function(){
    $('li a.current').toggleClass('current');
});

Solution 3

The other li elements are not siblings of the a element.

$('#menu li a').on('click', function(){
    $(this).addClass('current').parent().siblings().children().removeClass('current');
}); 

Solution 4

You can do this:-

$('#about-link').addClass('current');
$('#menu li a').on('click', function(e){
    e.preventDefault();
    $('#menu li a.current').removeClass('current');
    $(this).addClass('current');
});

Solution 5

You can try this,

$(function () {
   $("#btnSubmit").click(function () {
   $("#btnClass").removeClass("btnDiv").addClass("btn");
   });
});

you can also use switchClass() method - it allows you to animate the transition of adding and removing classes at the same time.

$(function () {
        $("#btnSubmit").click(function () {
            $("#btnClass").switchClass("btn", "btnReset", 1000, "easeInOutQuad");
        });
    });
