jQuery Drop down menu without setTimeout

I worked a lot with drop-down menus like most of you. There are many stable versions of DD menus using pure javascript & CSS or only CSS with cross-browser support and you’ll get them free from many menu maker websites or desktop applications. So I’m not going to reinvent the wheel.

I’m a freaking fan of jQuery and always use it for drop-down menus with my custom jQuery code. It’s a must to use a delay for javascript driven dd menus even for jQuery when you want to give it some effect like slideDown or slideUp (For CSS dropdown menus it’s not possible & thus no need to use delay). I always wished to use jQuery without any setTimeout function for the drop-down menus. And I did it which I’m gonna share with you.

$(function () {
    $("ul>li").hover(function () {
        $(this).find("ul.sub").slideDown('fast');
        $(this).addClass("hover");
        $(this).hover(
        function () {},
        function () {
            $(this).find("ul.sub").slideUp('fast');
        });
    },
    function () {
        $(this).removeClass("hover");
    })
})

Here it is in action

The main tricky part is using hover inside hover function:

$(this).hover(
function () {},
function () {
    $(this).find("ul.sub").slideUp('fast');
});

This removes the mouseover function (first function of hover) when mouse hover into the li so the slideDown does not happen again when the mouse enter into the inner ul/li. Hope that makes sense. You may like to add a delay and do some more fine tunes.

Happy Coding!
