This is for Bootstrap v3. I wanted to use the following code to change active class when I click on the list item but it doesn't work.
<script type="application/javascript">
$( document ).ready(function() {
$(".nav li").on("click", function() {
$(".nav li").removeClass("active");
$(this).addClass("active");
});
});
</script>
Here is the full html.
