fadeIn working on hover but not onClick/click

Question

Showing sublist items fades in on hover(), but not click() or onclick(). http://jsfiddle.net/gymbry/mgMK4/

Answer 1

Simplest solution:

$('ul li').click(function (e) { //  jQuery click event. The "e" is the "event" argument
    e.stopPropagation();    //  prevents a parent elements "click" event from fireing (useul here since this asigns to inner li's as well)
    var ul = $(this).children('ul');    //  find any children "ul" in this li
    //  check if ul exist and toggle (not completely neccesary as jquery will simply preform no action if element is not found)
    if (ul.length) ul.fadeToggle('fast');
});

$('ul li').click(function (e) { //  jQuery click event. The "e" is the "event" argument
    e.stopPropagation();    //  prevents a parent elements "click" event from fireing (useul here since this asigns to inner li's as well)
    var ul = $(this).children('ul');    //  find any children "ul" in this li
    if (ul.length) {    //  check if ul exist
        if (ul.is(':visible')) {    //  check ul is visible
            ul.fadeOut('fast');
        }
        else {
            ul.fadeIn('fast');
        }
    }
});

Keep in mind, the above solution doesn't deal with siblings or deeper menus being open upon close. For a more full solution, try the following:

$('ul li').click(function (e) {
    e.stopPropagation();
    var ul = $(this).children('ul');

    $(this).siblings().each(function(i) {
        var ul = $(this).children('ul');
        if (ul.length) if (ul.is(':visible')) {
            ul.find('ul').fadeOut('fast');
            ul.fadeOut('fast');
        }
    });

    if (ul.length) {
        if (ul.is(':visible')) {
            ul.find('ul').fadeOut('fast');
            ul.fadeOut('fast');
        }
        else ul.fadeIn('fast');
    }
});
