One opportunity to interact with the menu by clicking only once

I am encountering an issue with a menu div that starts off with opacity set to 0 and visibility hidden. The purpose is for this div to become visible when clicking on another div (a menu that sticks to the top of my page, toggle-able via click).

Everything works perfectly... the FIRST TIME...

When I click on "#menuIcon" the menu becomes available. I can show and hide it without any problems. However, after hiding the menu once, it remains hidden and cannot be made visible again. Can someone assist me in resolving this issue??

jQuery code
/* Toggles menu visibility on clicks */
$('#menuIcon').click(function () {
    if ($('#menu ul').css('visibility') == 'hidden') {
        $('#menu ul').css('visibility', 'visible');
        $('#menu ul').animate({
            opacity: 1
        }, 500);
    } else {
        $('#menu ul').animate({
            opacity: 0
        }, 500,
        function () {
            $('#menu ul').css('visibility', 'hidden');
        });
    }
});

Answer №1

Don't forget to properly close the parentheses in your animate script. Here is the corrected version:

$('#menuIcon').click(function () {
    if ($('#menu ul').css('visibility') == 'hidden') {
        $('#menu ul').css('visibility', 'visible');
        $('#menu ul').animate({
            opacity: 1
        }, 500);
    } else {
        $('#menu ul').animate({
            opacity: 0
        }, 500,
        function () {
            $('#menu ul').css('visibility', 'hidden');
        });
}
});

Remember, JSFiddle can be a helpful tool to clean up your script and spot errors.

Spelling Mistake:

$('#menu ul').animate({opacity : 0 }, 500, function() {
            $('#menu ul').css('visibility','hidden');
        });

JS

$(".menu").click(function()
                 {

                 });

Answer №4

Give this a try: Use a variable to track if the menu has been displayed at least once, and include it in your conditional statement.

Please note: You can utilize is(':visible') instead of .css('visibility'), and employ show() / hide() to toggle the visibility of the menu as demonstrated in the code snippet below

var hasBeenShown = false;
/* Reveals menu upon clicks */
$('#menuIcon').click( function() {
    // Check if the menu has not been shown before and is currently invisible
    // If so, display the menu
    if(!hasBeenShown  && !$('#menu ul').is(':visible')) {
        // Set hasBeenShown to true
        hasBeenShown  = true;
        $('#menu ul').animate({opacity : 1 }, 500,function(){
           $('#menu ul').show();
       });
    }
    else {   
        $('#menu ul').animate({opacity : 0 }, 500), function() {
            $('#menu ul').hide();
        });
    }
});
