jQuery.addClass function not functioning correctly

I am encountering an issue where the functionality in this code snippet isn't quite working as expected. Specifically, I would like the 'huh' div to become opaque when the menu is hovered over. While attempting to achieve this with fadein/out methods, it only worked once which was rather peculiar.

 <script type="text/javascript">
    $( function() {
        $('#menuNav').hover( function() {
            $('#huh').addClass('.opacity');
        }, function(){
            $('#huh').removeClass('.opacity');
        });
    });

</script>

.opacity {
    opacity: 0.3;
}

Answer №1

Try utilizing it without the period:

 $(function(){

        $('#menuNav').hover(function(){

            $('#huh').addClass('opacity');
        }, function(){
            $('#huh').removeClass('opacity');
        });
    });

Answer №2

$(document).ready( function() {
    $('#menuNav').on('mouseenter', function() {
        $('#huh').toggleClass('opacity');
    });
});

Answer №3

.hover() can trigger many events, so it's generally recommended to use .mouseenter() instead. It's important to note that when adding a class, you don't need to include the . (dot).

$(function(){

        $('#menuNav').mouseenter(function(){

            $('#huh').addClass('opacity');
        }, function(){
            $('#huh').removeClass('opacity');
        });
    });

Answer №4

Utilize this method to eliminate the period:

    $('#huh').addClass('opacity'); // remove .

 $('#huh').removeClass('opacity'); // remove .

==============

Or you can use: 

toggleClass in jquery

$(function(){

        $('#menuNav').hover(function(){
            $('#huh').toggleClass('opacity');
        });
    });

Answer №5

Give this a shot

 <script>
    $(document).ready(function(){
        $('#menuNav').hover(function(){
            $('#huh').addClass('opacity');
        }, function(){
            $('#huh').removeClass('opacity');
        });
    });
</script>

Answer №6

You must remember not to include the dot in your class name when using addClass and removeClass. Simply add or remove the class without the dot when calling these methods. For example:

$(function() {
    $('#menuNav').hover(function(){
        $('#huh').addClass('opacity');
    }, function(){
        $('#huh').removeClass('opacity');
    });
});

Answer №7

. In order to achieve this effect, first delete the existing code and then implement the following JavaScript:

 $(function(){
    $('#menuNav').hover(function(){
        $('#huh').toggleClass('opacity');
    });
});

Answer №8

Give this a shot

$("#menuNav").hover(function() {
    $('#huh').toggleClass('opacity');
});
