To know if mouse still hover menu - javascript

I have the following menu construction very resumed (cant change HTML code due is impossible, only CSS and JS!):
$('span').on("hover", handleHover('span'));
function handleHover(e) {
$(e).on({
mouseenter: function() {
$(this).addClass('selecc');
$(this).next("ul").show();
},
mouseleave: function() {
$(this).removeClass('selecc');
$(this).next("ul").hide();
}
});
}
span {
display:block;
}
ul {
background-color:#CCC;
color:#000;
display:none;
margin:0;
}
.selecc {
background-color:Red;
color:#FFF
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<span>Option 1</span>
<ul>
<li>suboption 1-1</li>
<li>suboption 1-2</li>
<li>suboption 1-3</li>
</ul>
<span>Option 2</span>
<ul>
<li>suboption 2-1</li>
<li>suboption 2-2</li>
<li>suboption 2-3</li>
</ul>
I need to move the mouse over the suboptions but the menu closes and i dont know how to tell to jquery that UL is part of menu group. Some idea for this?

No-one said you cannot alter the HTML dynamically using jQuery :)
So, yes, group your SPAN+UL into groups, and attach the hover function to your .group wrapper:
jsBin demo
$("span").each(function(){
var ul = $(this).next("ul");
$(this).add(ul).wrapAll("<div class='group'/>");
});
$(".group").hover(handleHover);
function handleHover() {
$("span",this).toggleClass('selecc');
$("ul",this).stop().slideToggle();
}

Make CSS Hover work when the element is hidden using javascript

I have a menu where there are the heading and the submenus. Whenever the user hovers over the heading, submenus show up.
And whenever any of the items in submenus is clicked, the submenu is set to hidden using Javascript. Now, when the user hovers over the menu, the submenus don't show up! Please help me to fix this.
function closesSan() {
document.getElementsByClassName('submenu')[0].style.setProperty('display', 'none', 'important');
}
#main:hover .submenu {
display: block!important;
}
<ul>
<li id="main">
List
<ul class="submenu" style="display: none;">
<li onclick="closesSan()">Bacon</li>
<li onclick="closesSan()">Tuna</li>
<li onclick="closesSan()">Chicken</li>
</ul>
</li>
</ul>
I had to write some additional code to get the desired result. Actually, the base problem in your code was important and property {both works same} in sense both get prioritized by code.
So to get rid of I have added an additional class on click and removing that class on every new hover. Hope it will satisfy the needs.
var main = document.getElementById("main");
main.onmouseover = function() {
document.querySelector('.submenu').classList.remove("displayNoneImp");
}
function closesSan() {
document.querySelector('.submenu').classList.add("displayNoneImp");
}
.submenu {
display: none;
}
#main:hover .submenu {
display: block;
}
.displayNoneImp {
display: none !important;
}
<ul>
<li id="main">
List
<ul class="submenu">
<li onclick="closesSan()">Bacon</li>
<li onclick="closesSan()">Tuna</li>
<li onclick="closesSan()">Chicken</li>
</ul>
</li>
</ul>
Since you don't use a pure CSS implementation, use event listeners and avoid using !important whenever possible:
var main = document.querySelector('#main');
var submenu = document.querySelector('.submenu');
var items = document.querySelectorAll('#main li');
main.addEventListener('mouseover', function () {
submenu.style.display = 'block';
});
main.addEventListener('mouseout', function () {
submenu.style.display = 'none';
});
items.forEach(function(item) {
item.addEventListener('click', function () {
console.log('clicked on:', item)
submenu.style.display = 'none';
});
});
.submenu {
display: none;
}
<ul>
<li id="main">
List
<ul class="submenu">
<li>Bacon</li>
<li>Tuna</li>
<li>Chicken</li>
</ul>
</li>
</ul>
When Using !important is The Right Choice
You can try something simple like this:
function closesSan() {
document.getElementsByClassName('submenu')[0].classList.add("hide");
setTimeout(function() {
document.getElementsByClassName('submenu')[0].classList.remove("hide");
},100)
}
#main .submenu {
display: none;
}
#main:hover .submenu {
display: block;
}
#main .submenu.hide {
display: none;
}
<ul>
<li id="main">
List
<ul class="submenu" >
<li onclick="closesSan()" >Bacon</li>
<li onclick="closesSan()">Tuna</li>
<li onclick="closesSan()">Chicken</li>
</ul>
</li>
</ul>
use visibility instead of display
visibility: hidden;
save those kittens

Dropdown Menu: Infinite Slide on Hover with jQuery

I have created a simple dropdown menu with jquery
https://jsfiddle.net/pmksgz3w/
HTML
<ul>
<li>Page A</li>
<li>Page B
<ul>
<li>Dropdown</li>
<li>Dropdown</li>
</ul>
</li>
</ul>
Jquery
$(document).ready(function(){
$('ul> li').hover(function() {
$(this).find('ul').slideToggle();
});
});
When I hover over Page B, then the dropdown menu is shown. If I move the curser from Page B very slowly to the right (see picture) then the drop-down menu will close, since the li is not hovered for a short moment. How can I prevent that the dropdown menu will instantly close?
An even worse problem happens if I move the cursor extremely fast to the dropdown menu. Because then, the dropdown menu will slideUp and slideDown in an infinite loop.
I found at How to tell .hover() to wait? a promising solution from 2009 but the answer does not work when I try it,(Edit note: It works now, see edit below). Further it is mentioned that one should use hoverIntend plugin. I downloaded the plugin and changed my jQuery code to
$(document).ready(function(){
$('ul> li').hoverIntend(function() {
$(this).find('ul').slideToggle();
});
});
and although it improves some things, the above problem that it instantly closes and the infinite loop remains. How can I solve this problem?
Edit: I managed to solve the first problem! Now the dropdown does not close instantly!
https://jsfiddle.net/5sxvsu8w/
I had to change the jQUery code as follows:
$(document).ready(function(){
var timer;
$('ul> li').hover(function() {
clearTimeout(timer);
$(this).find('ul').slideDown('fast');
}, function() {
var list = $(this).find('ul');
timer= setTimeout(function() {
list.slideUp('fast');
}, 2000);
});
});
However, the infinite loop problem remains.
The solution you found in here is usefull, this javascript code maybe can help:
$(document).ready(function(){
$('.menu li').hover(
function () {
$('.sub', this).stop().slideDown(650);
},
function () {
$('.sub', this).stop().slideUp(650);
}
);
});
/*$('ul >li').hover(function() {
clearTimeout($(this).data('timeout'));
$('li > ul').slideDown('fast');
}, function() {
var t = setTimeout(function() {
$('li > ul').slideUp('fast');
}, 650);
$(this).data('timeout', t);
});*/
li{
list-style-type:none;
display: inline-block;
position: relative;
padding: 20px;
background-color: #08c;
}
li ul li{
min-width:200px;
}
li ul{
margin:0;
padding:0;
position: absolute;
top: 100%;
left:0;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<ul class="menu">
<li>Page A</li>
<li>Page B
<ul class="sub">
<li>Dropdown</li>
<li>Dropdown</li>
</ul>
</li>
</ul>
EDIT: I have changed my javascript code after some reseach; this solution unfortunately does not solve completely the first problem (it is still based on a timer) but avoids the infinite loop.

jQuery navigation-items with nested submenus should open on click

I need to add a second level of submenus here.
Is there a dynamic solution, so only one submenu is opened, when clicking on the link?
And when clicking a link to a submenu (in the first submenu), then open this one?
And so on…
I already changed the jsfiddle a little, to have one level of sublevels more: http://jsfiddle.net/cRsZE/363/
Working example with one level of submenus: JSFiddle Demo
HTML:
<ul id="nav">
<li>Home</li>
<li class="parent">About
<ul class="sub-nav">
<li>Johnny</li>
<li>Julie</li>
<li>Jamie</li>
</ul>
</li>
<li>Contact</li>
</ul>
CSS:
#nav ul.sub-nav {
display: none;
}
#nav ul.visible {
display: block;
}
jQuery:
$(document).ready(function() {
$('.parent').click(function() {
$('.sub-nav').toggleClass('visible');
});
});
Source: Creating Drop Down Menu on click CSS
Try,
CSS:
.hidden {
display: none;
}
JS:
$('ul ul').addClass('hidden');
$(document).ready(function () {
$('.parent').click(function (e) {
e.stopPropagation();
$(this).find('ul').first().toggleClass('hidden');
});
});

Menu Item Hover JavaScript

If someone could help me point in the right direction that would be awesome as I have been looking for a solution to this issues for hours.
http://jamessuske.com/will/
I have a menu with 3 menu items on it. if you hover over the last two menu items, a div with items from a different list appear. That part works fine, but if I go to roll over the other menu items from another list, they disappear again.
This is my JavaScript:
<script type="text/javascript">
function showGalleryNav(){
document.getElementById('headerNavGallery').style.display = "";
}
function showInfoNav(){
document.getElementById('headerNavInfo').style.display = "";
}
function hideGalleryNav(){
document.getElementById('headerNavGallery').style.display = "none";
}
function hideInfoNav(){
document.getElementById('headerNavInfo').style.display = "none";
}
</script>
And The HTML
<div class="headerNav">
<ul>
<li>Home</li>
<li>Gallery</li>
<li>Info</li>
</ul>
</div><!--headerNav-->
<div class="headerNavGallery" id="headerNavGallery" style="display:none;">
<ul>
<li>Categoies</li>
<li>Products</li>
</ul>
</div><!--headerNavGallery-->
<div class="headerNavInfo" id="headerNavInfo" style="display:none;">
<ul>
<li>William Ruppel</li>
<li>CV</li>
<li>Artist Bio</li>
<li>Video</li>
<li>Contact</li>
</ul>
</div><!--headerNavInfo-->
I've tried different Attributes, but none of them are working, I have also tried switching to jQuery with
$('#headerNavGallery").css("display", "");
also didn't work,
Any ideas would be greatly apperiated.
Actually what you are trying to accomplish is all css-only doable but not with that markup structure. First you need to nest your lists.
<ul class="menu">
<li>item 1</li>
<li>
item 2 with sub
<ul>
<li>sub menu item 1</li>
<li>sub menu item 2</li>
... so on ..
</ul>
</li>
</ul>
some css
.menu li {
position: relative;
}
.menu li ul {
position: absolute;
top: 30px; /* the height of the root level item */
display: none;
}
.menu li li {
position: static; /* or you could float these for horizontal menu */
}
.menu li:hover ul {
display: block;
}
These are pretty much the basics. But I strongly suggest you go and study superfish menu as it's jquery drop drop menu but it degrades nicely with js off, so you could just study the css of it. http://users.tpg.com.au/j_birch/plugins/superfish/
Check that typeo, nvm...
Setting the display property should always have a value "none" or "block", empty("") is a bad reset... try this:
<script>
$(".galleryNavToggle").on("mouseenter mouseleave", function(event){
var headNavGal = $("#headerNavGallery");
if(event.type === "mouseenter"){
headNavGal.show();
}else if(event.type ==="mouseleave" &&
((event.relatedTarget !== headNavGal[0] && $.inArray(event.relatedTarget, headNavGal.find("*")) <=0) ||
$.inArray(event.relatedTarget, $(".galleryNavInfoToggle")) > 0)){
headNavGal.hide();
}
});
$("#headerNavGallery").on("mouseleave", function(event){
var headNavGal = $(this);
if(event.type ==="mouseleave"){
headNavGal.hide();
}
});
</script>
HTML
<div class="headerNav">
<ul>
<li>Home</li>
<li><a href="" class='galleryNavToggle'>Gallery</a></li>
<li><a href="" class='galleryNavInfoToggle'>Info</a></li>
</ul>
</div><!--headerNav-->
<div class="headerNavGallery" id="headerNavGallery" style="display:none;">
<ul>
<li>Categoies</li>
<li>Products</li>
</ul>
</div><!--headerNavGallery-->
AND CSS
.headerNav{
border:thin solid black;
float:left;
}
.headerNavGallery{
float:left;
border:thin solid black;
margin-left:-1px;
}
1) Gallery
You don't need to specify javascript:. This is redundant.
2) It is working exactly the way you programmied it to work. When you mouse-out, it disappears.
3) You have code for "headerNavInfo" but no matching HTML.

2 column layout for submenus

I am trying to create sort of Jquery Ui megamenu's or even suckerfish style. But can not use them as a plugin in my code.
I have a 2 column layout in my sub menus. How do I tweak the existing code to show it in a 2 column layout? Here's my jsfiddle.
To my understanding, i will have to play a lot with css in this. As I tried doing it by having 2 Unordered list in the main list and gave float right and left consecutively and used clear both.
As you can find that one column already exists.the other column would be dynamically updated through ajax call.
Any help would be appreciated.
Here's a simple demo:
http://jsfiddle.net/brvX3/11/
html:
<ul>
<li>Menu item
<div style="display:none">
<ul>
<li>Menu2 item1</li>
<li>Menu2 item1</li>
</ul>
<ul>
<li>Menu2 item2</li>
<li>Menu2 item2</li>
</ul>
</div>
</li>
<li>Menu item</li>
<li>Menu item</li>
</ul>
CSS:
body {
font-family:arial;
font-size:10px;
}
ul, li {
margin:0;
passing:0
}
ul > li {
float:left;
position:relative;
}
ul li a {
display:block;
padding:3px;
width:80px;
background-color:#e0e0e0
}
ul div {
position:absolute;
width:180px;
background-color:#e0e0e0
}
ul ul {
float:left;
width:90px
}
ul li a:hover > div {
display:block;
}
JS:
$("ul a").hover(
function(){ $(this).next().show() },
function() { $(this).next().hide() }
);
$("ul div").hover(
function(){ $(this).show() },
function() { $(this).hide() }
)
