I have a menu-submenu-subsubmenu construction in HTML like this:
<menu>
<li>Item 1</li>
<li><ul>
<li>Subitem 1</li>
<li>Subitem 2</li>
<li><ul>
<li>Sub-subitem 1</li>
<li>Sub-subitem 2</li>
<li>Sub-subitem 3</li>
</ul>
Subitem 3</li>
<li>Subitem 4</li>
</ul>
Item 2
</li>
<li>Item 3</li>
<li>Item 4</li>
...using whit this css formating:
menu {
display: block;
width: 200px;
}
/* hide subitems */
menu li ul,
menu li ul li ul {
display: none;
position: absolute;
}
/* set up positions */
menu li ul {
left: 200px;
width: 200px;
}
menu li ul li ul {
left: 400px;
width: 200px;
}
I use this jQuery code:
$(function() {
/* hide all submenu */
$('menu').find('ul').hide();
/* show submenu on mouseenter */
$('menu li a').mouseenter(function() {
$(this).parent().children('ul').show();
}).mouseleave(function() {
$(this).parent().children('ul').hide();
});
});
How can I detect mouse is leaving the element to their child? Or how can I get the child element to stay if it's necessary?
Change your code to be like this:
$(function() {
/* hide all submenu */
$('menu').find('ul').hide();
/* show submenu on mouseenter */
// here, just select the direct child
$('menu').find('li > a, li > ul').mouseenter(function() {
var time = new Date().getTime();
$(this).parent().find('ul').show().data('showing-time', time);
}).mouseleave(function() {
var leaveTime = new Date().getTime();
var $this = $(this);
window.setTimeout(function () {
var $ul = $this.parent().find('ul');
var beginTime = $ul.data('showing-time') || 0;
if (leaveTime > beginTime) {
$this.parent().find('ul').hide().data('showing-time', 0);
}
}, 100);
});
});
Hope this helps.

Code updated.
I suggest just put the sub menus next to the parent menu item(here, means li > a element) to get a better result.
Here's how I would go about it. You don't need javascript at all, at least not for simple hiding/showing. But, if you want to add delays, I would strongly suggest using jquery only to add/remove appropriate css classes with a settimeout.
css:
.menu {
position: relative;
display: inline-block;
}
.submenu {
display: none;
position: absolute;
left: 100%;
}
.menu li:hover > .submenu, .submenu.show {
display: inline-block;
}
html:
<ul class="menu">
<li>Item 1</li>
<li><ul class="submenu">
<li>Subitem 1</li>
<li>Subitem 2</li>
<li><ul class="submenu">
<li>Sub-subitem 1</li>
<li>Sub-subitem 2</li>
<li>Sub-subitem 3</li>
</ul>
Subitem 3</li>
<li>Subitem 4</li>
</ul>
Item 2
</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
js:
$('body').on('mouseleave','.submenu', function(e) {
var jTarget = $(e.currentTarget).addClass('show');
setTimeout(function() {
jTarget.removeClass('show');
}, 500);
})

I wonder if someone can please advise me how I can do the following?
I have the below JS which changes the background colour of an li based on id (I'm using the li as buttons). When the li is clicked the background turns white. Can someone please tell me what I should add to return all other li elements to their original colour?
Many thanks
$(function () {
$("li").click(function (e) {
document.getElementById(e.target.id).style.backgroundColor = "#fff";
});
});
You can do this more easily with a class:
$('li').on('click', function() {
$('.whitebg').removeClass('whitebg');
$(this).addClass('whitebg');
});
body {
background: deepskyblue;
}
li {
background: green;
display: inline-block;
cursor: pointer;
padding: 4px 8px;
}
.whitebg {
background: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
<li>Item 5</li>
</ul>
Okay so here is a cut down of what I have so far JSFiddle. Hovering over 'Aviation' brings down the menu. I would like it so that when you open the menu the first menu item is already set to active but also need the current hovered selection to stay selected when they move over the the "Related Links" side of the drop down.
I know very little JS but this is what I have come up with so far to make the menu appear.
$(document).ready(function() {
$(".aviation").hover(function() {
$(".aviation-menu").toggleClass("active");
});
});
$(document).ready(function() {
$(".aviation-menu").hover(function() {
$(".aviation-menu").toggleClass("active");
});
});
$(document).ready(function() {
$("#top li").hover(function() {
$(this).addClass("active");
}, function() {
$(this).removeClass("active");
});
});
Any help would massively be appriciated thank you.
I think you can use it like below, I gave the Jsfiddle link at the bottom as well:
$(document).ready(function() {
$(".aviation").hover(function() {
$(".aviation-menu").toggleClass("active");
});
});
$(document).ready(function() {
$("li").hover(function() {
$("li").each(function() {
$(this).removeClass("active");
});
$(this).addClass("active");
});
});
JSFIDDLE
Basically you will be removing all the "active" classes on the other list items when any of them gets hovered, so it will have one active all the time.
Edit: You can also add this $("li").first().addClass("active"); at the beginning so it will have "Home" as active by default.
You should consider the following: There is no "hovering" on mobile devices and what you're doing with JS (adding a class on hover, but actually what you want is a visual change) can be done with CSS, which is nicer in my opinion.

I have a scrollable dropdown menu and I want to keep the last item fixed and always visible on top while all the other items would scroll. However, with my solution it's really jumpy. Here's what I have so far:
HTML:
<ul class="menu">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
<li>Item 5</li>
<li>Item 6</li>
<li>Item 7</li>
<li>Item 8</li>
<li>Item 9</li>
<li class="fixed">Item 10</li> <!-- this item will be fixed and always on top -->
</ul>
Javascript:
this.$('.menu').on('scroll', function() {
if (stickyItem = $('.fixed')) {
//get the y position of the parent
topHeight = stickyItem.parent().offset().top;
//how far apart the sticky item should always be from the top of the bar
heightDiff = stickyItem.parent().height() - stickyItem.height();
if ((stickyItem.offset().top - topHeight) < heightDiff) {
heightApply = heightDiff + ( heightDiff - (stickyItem.offset().top - stickyItem.parent().offset().top));
stickyItem.css('top', (heightApply)+'px');
}
}
});
CSS:
ul li.fixed {
position: absolute;
bottom: 0;
}
Is there an easier way to accomplish what I'm trying to do? Thanks!
I have not tested anywhere besides chrome, but here's a pure CSS solution for your problem:
html,body{height:100%; margin:0; padding:0}
ul {margin: 0; padding:0; height:auto;
/*this padding bottom allows the penultimate element to be displayed*/
padding-bottom:39px}
ul li {padding:10px; background:#eee; color:#333;
font-family:sans-serif; border-bottom:1px solid #CCC; }
ul li.fixed { /*you could also use the :last pseudo selector*/
width:100%;
position: fixed;
bottom: 0;
background:lightblue;
}

I have recently started designing a mobile website using media queries and browsing a few websites to see what they've done it seems accordion navigation menus are the way to go, scaling up to a normal horizontal navigation bar. I have browsed and browsed the internet looking for an accordion walkthrough but I can not seem to find one that explains it well enough.
A good example is the one from microsoft on their website. Here is my code so far:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<style>
body {
padding: 0;
margin: 0;
}
#topMenu {
height: 50px;
width: 100%;
background-color: #cde;
display: block;
}
nav {
width: 100%;
height: auto;
display: block;
margin: 0;
padding: 0;
}
nav a {
text-decoration: none;
padding-left: 40px;
}
nav ul {
list-style: none;
display: block;
margin: 0;
padding: 0;
background-color: #ccc;
}
nav ul li {
display: block;
width: 100%;
padding: 20px 0px 20px 0px;
border-top: 2px solid #abc;
}
nav ul ul {
height: 0;
overflow: hidden;
padding-top: 0px;
}
nav ul ul li a {
padding-left: 100px;
}
</style>
</head>

These navigation bars have submenus [nav ul ul] that slide out when nav ul li is clicked. I was hoping somebody could point me in the right direction as to how I go about making a slide down sub menu on click, or help me with the code.
I thought there may have been a basic one people could start using and edit to customise themselves.
Thanks for any help.
There is no need for Javascript - you may use a Checkbox instead.
Check out: http://codepen.io/TimPietrusky/pen/CLIsl
If you still want to do it with Javascript go for something like this:
// asuming, that nav-items that should trigger slidedown will have "#" as href
// while actual nav-items will have URLs
$('nav li a[href="#"]').on('click', function (e) {
// prevent Click from redirecting
e.preventDefault();
// get the next ul after the li a clicked
if ($(this).hasClass('visible')) {
$(this).next('ul').slideUp(200).removeClass("visible");
} $(this).next('ul').slideDown(200).addClass("visible");
});
CSS animation for height form 0 to auto wont work. See: How can I transition height: 0; to height: auto; using CSS?

Unfortunately CSS does not have any click events, instead you will need to use JavaScript and/or jQuery. I used jQuery
All i did was add a class hide-nav to your nav with display none. And a button to click of course.
And a bit of jQuery
$(document).ready(function() {
$('#topMenu-btn').on('click', function() {
$('nav').slideToggle();
});
});
Try something like this:
http://jsfiddle.net/kb668aag/
You'll need to modify the code a bit.
<div id="topMenu"></div>
<nav>
<ul>
<li>Link</li>
<li class="has_children">Link
<ul class="sub-menu">
<li>Link 1</li>
<li>Link 2</li>
<li>Link 3</li>
<li>Link 4</li>
<li>Link 5</li>
<li>Link 6</li>
<li>Link 7</li>
</ul>
</li>
<li class="has_children">Link
<ul class="sub-menu">
<li>Link 1</li>
<li>Link 2</li>
<li>Link 3</li>

Everything works as it should as far as the animation, ect.
However, when I add a link into the

var button = buttons[i];
button.onclick = setSelected;
}
function setSelected(e) {
if (this.classList.contains("selected")) {
this.classList.remove("selected");
if (!this.parentNode.classList.contains("radmenu")) {
this.parentNode.parentNode.parentNode.querySelector("a").classList.add("selected")
} else {
this.classList.add("show");
}
} else {
this.classList.add("selected");
if (!this.parentNode.classList.contains("radmenu")) {
this.parentNode.parentNode.parentNode.querySelector("a").classList.remove("selected")
} else {
this.classList.remove("show");
}
}
return false;
}
Just modify your javascript code to following,
function setSelected(e) {
if(this.getAttribute("href") == "#"){
if (this.classList.contains("selected")) {
this.classList.remove("selected");
if (!this.parentNode.classList.contains("radmenu")) {
this.parentNode.parentNode.parentNode.querySelector("a").classList.add("selected")
} else {
this.classList.add("show");
}
} else {
this.classList.add("selected");
if (!this.parentNode.classList.contains("radmenu")) {
this.parentNode.parentNode.parentNode.querySelector("a").classList.remove("selected")
} else {
this.classList.remove("show");
}
}
return false;
}
else{
return true;
}
}
Basically the return false; was preventing the page to perform the default action of going to the assigned href.
