assistance in incorporating CSS classes using jQuery

In an attempt to modify the bottom border color of my navigation bar based on the link being hovered over, I want the bottom border color to change to match that of the hovered link. When the link loses focus or hover, the navigation bottom-border should revert to its original color. Below you can find my HTML and jQuery code snippet.

<nav>
            <ul class="<?php echo $ul; ?>">
                <li class="home"><a class="home" href="/">Home</a></li>
                <li class="letters"><a class="letters" href="/product/type/letters">Letters</a></li>
                <li class="business active"><a class="active business" href="/product/type/business">Business</a></li>
                <li class="cards"><a class="cards" href="/product/type/cards">Cards</a></li>
                <li class="gifts"><a class="gifts" href="/product/gifts">Gifts</a></li>
            </ul>
        </nav>

/jQuery/

$('nav li a').hover(function(){
            var orginalClass = $(this).parent().parent().attr('class');
            $(this).parent().parent().attr('class', '');
            var classType = $(this).attr('class');
            $(this).parent().parent().addClass(classType);
        }, 
        function() {
            $(this).parent().parent().attr('class', '');
            $(this).addClass(orginalClass);
        });

Answer №1

The issue lies within the scope of your "originalClass" variable. It is confined to the initial hover function, making it off-limits in the subsequent function.

A better approach would be to incorporate a secondary CSS class for toggling, allowing it to override the properties of the first class.

Answer №2

let currentClass='';   
$('header ul li a').hover(function(){
    let ul = $(this).closest('ul');
    currentClass = ul.attr('class');
    let classType = $(this).attr('class');
    ul.removeClass().addClass(classType);
}, 
function() {
    ul.removeClass().addClass(currentClass);
});

Answer №3

Check out this code snippet:

$('nav li a').each(function() {
  var savedClass = $(this).parents('nav').first().attr('class');
  $(this).hover(function() {
    $(this).parents('nav').first().attr('class', $(this).attr('class'));
  }, function() {
    $(this).parents('nav').first().attr('class', savedClass);
  });
});

Answer №4

$('nav ul li a').hover(function(){
            var ulElement = $(this).closest('ul');                                              
            ulElement.data('originalStyle', ulElement.attr('style') );             
            ulElement.removeClass( ulElement.data('originalStyle') );             
            ulElement.addClass( $(this).attr('style') );
        }, 
        function() {
            var ulElement = $(this).closest('ul'); 
            ulElement.removeClass( $(this).attr('style') ); 
            ulElement.addClass( ulElement.data('originalStyle') );
        }
);
