Struggling to make fadeIn() function properly in conjunction with addClass

I've been struggling with this issue for quite some time now and I just can't seem to make it work. The JavaScript I'm working on involves using addClass and removeClass to display and hide a submenu element. While the addclass and removeClass functions are functioning properly, I'm having trouble getting fadeIn and fadeOut to work as intended. I have experimented with the animate function, but so far, it hasn't provided a solution. Someone suggested trying out toggleClass, which I plan to investigate further at a later time.

jQuery(document).ready(function (e) {
    function t(t) {
        e(t).bind("click", function (t) {
            t.preventDefault();
            e(this).parent();
        });
    }
    e(".dropdown-toggle").click(function () {
        var t = e(this).parents(".button-dropdown").children(".dropdown-menu").is(":hidden");
        e(".button-dropdown .dropdown-menu").hide();
        e(".button-dropdown .dropdown-toggle").removeClass("active");
        if (t) {
            e(this).parents(".button-dropdown").children(".dropdown-menu").toggle().parents(".button-dropdown").children(".dropdown-toggle").addClass("active"); //i believe that this is where i need to toggle the fadeIn and FadeOut
        }
    });
    e(document).bind("click", function (t) {
        var n = e(t.target);
        if (!n.parents().hasClass("button-dropdown")){ 
            e(".button-dropdown .dropdown-menu").hide();
        }
    });
    e(document).bind("click", function (t) {
        var n = e(t.target);
        if (!n.parents().hasClass("button-dropdown")){
            e(".button-dropdown .dropdown-toggle").removeClass("active"); 
        }
    })
});

The HTML snippet related to this issue:

<nav class="nav2">
<a href="profile.php" class="imglink"><img src="img/icon-profile.png" WIDTH=40 HEIGHT=40></a>
<li class="button-dropdown">
<a href="javascript:void(0)" class="dropdown-toggle"><img src="img/cart.png" class="cart"WIDTH=40 HEIGHT=40></a>
<ul class="dropdown-menu" style="list-style:none;">
<p>
<h2 class="profileH2">Winkelwagen</h2>
</p>
</ul>
</li>
</nav>

This piece of code controls the visibility of the submenu within the button-dropdown. Any assistance in resolving this issue would be greatly appreciated.

Thank you

Replace the use of fadeOut with hide, and switch from fadeIn to toggle (which essentially works as show since it begins by hiding the element).

https://jsfiddle.net/eyemsa34/

e(".dropdown-toggle").click(function () {
    var t = e(this).parents(".button-dropdown").children(".dropdown-menu").is(":hidden");
    e(".button-dropdown .dropdown-menu").fadeOut();
    e(".button-dropdown .dropdown-toggle").removeClass("active");
    if (t) {
        e(this).parents(".button-dropdown").children(".dropdown-menu").fadeIn().parents(".button-dropdown").children(".dropdown-toggle").addClass("active"); //I think this is where I should toggle between fadeIn and fadeOut
    }
});

You can simplify the toggling logic by using fadeToggle and toggleClass provided by jQuery.

https://jsfiddle.net/eyemsa34/1/

e(".dropdown-toggle").click(function () {
    e(".button-dropdown .dropdown-menu").fadeToggle();
    e(".button-dropdown .dropdown-toggle").toggleClass("active");
});

Answer №2

Perhaps not the definitive solution, but a step in the right direction. This code snippet utilizes fading effects for dropdown menus without using addClass.

jQuery(function($) {
var $dropdownMenus = $('.dropdown-menu');
    
    $dropdownMenus.hide();
    
    $(".dropdown-toggle").on('click', function() {
    var $toggle = $(this),
        $toggleContainer = $toggle.parent(),
            $toggleMenu = $toggleContainer.find('.dropdown-menu');
        
        if ($toggleMenu.is(':hidden')) {
        $dropdownMenus.fadeOut('slow');
          $toggleMenu.fadeIn('slow');
        } else {
        $toggleMenu.fadeOut('slow');
        }
    });
});
