jQuery: Remove class if other element is clicked

Question

I have an ul-list that contains li-elements. When the user clicks on one of these li elements a class should be added to that element.

This is easy to setup, however, when the other li-element is clicked I want the "active"-class to be removed from the non-active li.

I have made a jsfiddle of the problem: http://jsfiddle.net/tGW3D/

There should be one li-element that is red at any one time. If you click the second and then the first, only the first should be red.

Answer 1

<script>
    $(function() {
        $('li').click(function() {
            $("li.active").removeClass("active");
                $(this).addClass('active');
            });
        });
</script>

Answer 2

You can use siblings and removeClass methods.

$('li').click(function() {
    $(this).addClass('active').siblings().removeClass('active');
});

Answer 3

Just remove all instances of .active first, and then add it:

$('ul li').on('click', function() {  
    $('ul li.active').removeClass('active');
    $(this).addClass('active');    
});

Answer 4

You change css class by this code:

$('li').click(function() {
    $(this).addClass('active').siblings().removeClass('active'); 
});

Answer 5

 $('li').click(function() {
      $(this).addClass('active'); // add the class to the element that's clicked.
      $(this).siblings().removeClass('active'); // remove the class from siblings. 
});

If you know jquery you can chain it like below.

 $('li').click(function() {
      $(this).addClass('active').siblings().removeClass('active'); 
});

Above code will do the trick for you. Try this demo

Answer 6

This will remove the active class from each li that have active and than will add to the Element which was clicked.

$('body').on('click', 'li', function() {
      $('li.active').removeClass('active');
      $(this).addClass('active');
});
