Manipulating anchor links with jQuery by adding and removing classes

I am struggling to understand why I cannot remove a class from an element and then add a new one. Changing the CSS using .css(...) works, but for some reason .removeClass and .addClass are not functioning.

Interestingly, I am able to successfully add and remove classes on some spans. Can anyone point me in the right direction? Thank you!

Here is the HTML:

<ul id="menu">
  <li><span>&nbsp;</span><span><a href="#">Home</a></span></li>
  <li><span>&nbsp;</span><span><a href="#">Test</a></span></li>
  <li><span>&nbsp;</span><span><a href="#">Test</a></span></li>
  <li><span>&nbsp;</span><span><a href="#">LaLa</a></span></li>
  <li><span>&nbsp;</span><span><a href="#">Test</a></span></li>
  <li><span>&nbsp;</span><span><a href="#">Blah</a></span></li>
 </ul>

Below is the CSS:

.menuText{

    text-decoration: none;
    color: red;

}

.menuTextA{
    text-decoration: none;
    color: #1A4588;
}

And here is the jQuery:

$('li', 'ul#menu').each(function() {

                $(this).mouseover(function() {

                    $('span', this).eq(0).removeClass('menuTabLeft'); // this works
                    $('span', this).eq(1).removeClass('menuTabRight'); // this works

                    $('span', this).eq(0).addClass('menuTabLeftA'); // this works
                    $('span', this).eq(1).addClass('menuTabRightA'); // this works

                    //$('a', this).eq(0).removeClass('menuText'); // this doesn't work 
                    //$('a', this).eq(0).addClass('menuTextA'); // this doesn't work

                    $('a', this).eq(0).css('color', '#1A4588'); // this works
    });
 });

Answer №1

Have you considered leveraging the CSS psuedo-selector for this task?

.menuText:hover{
    text-decoration: none;
    color: #1A4588;
}

Answer №2

What do you think about this quick solution:

$("#menu li").each(function() {
    $(this).mouseover(function() {
        var elements = $("span", this);
        $(elements[0]).removeClass("menuTabLeft").addClass("menuTabLeftA");
        $(elements[1]).removeClass("menuTabRight").addClass("menuTabRightA");
        $('a', this).removeClass("menuText").addClass("menuTextA");
    });
});

If you prefer a more effective solution (no script required):

#menu a {
    text-decoration: none;
    color: red;
     font-size: 30px;
}

#menu a:hover{
    text-decoration: none;
    color: #1A4588;
     font-size: 60px;
}
