Check if element is hovered over in jQuery

How can one check if the cursor is hovered over in jquery or js.
I have tried $('#id').is(':hover') but this doesnt seem to be working at all.
I have to mention that i am calling this line inside of a hover() function could this maybe be the problem?
here is my code:
$(document).ready(function() {
/* On hover function, over the menu items */
$('nav ul li').hover(function(){
$('nav ul li').css("background-color", "");
$('#append').css("background-color", "");
$(this).css("background-color", "#9999FF");
$('#append').css("background-color", "#9999FF");
var append;
if($('#menu-item-12')) {
append = 'news';
}else if($('#menu-item-9:hover')) {
append = 'account';
}else if($('#menu-item-11').is(':hover')) {
append = 'check out';
}
$('#appendp').empty();
$('#appendp').append(document.createTextNode(append));
});
Hope someone can tell me whats wrong.
here is jsfiddle link, i did my best :) https://jsfiddle.net/xsv325ef/

A nice way to do it is to store the related texts into an Object literal,
and recall the text depending on the hovered element ID:
fiddle demo
$(function() { // DOM ready shorthand ;)
var $appendEl = $('#appendp');
var id2text = {
"menu-item-12" : "unlock this crap",
"menu-item-9" : "check your gdmn account",
"menu-item-11" : "check the hell out"
};
$('nav ul li').hover(function(){
$appendEl.text( id2text[this.id] );
});
});
Regarding the colors... use CSS :hover

You just need to check if hovered item has this id.
Something like this: https://jsfiddle.net/hrskgxz5/5/
if(this.id === 'menu-item-11') {
append = 'check out';
alert('hovered');
}

$('li').hover(function(){
$(this).css("background-color", "#9999FF");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<ol>
<li>Coffee</li>
<li>Tea</li>
<li>Milk</li>
</ol>
<ul>
<li>Coffee</li>
<li>Tea</li>
<li>Milk</li>
</ul>

You should notice that jQuery .hover() function takes 2 handler function, and here you only provide one. Check the official documentation here.
In your case, you may just use .mouseover() to add a class on top of it, and then set your styles in css file. (Document here)
For example:
$(document.ready(function(){
$('nav ul li').mouseover(function() {
$(this).addClass('active');
});
});
If you do need to toggle the class for that element, the hover function should be as follow:
$(document.ready(function(){
$('nav ul li').hover(function() {
// Stuff to do when the mouse enters the element
$(this).addClass('active');
// Other styles you want to do here
// ...
}, function() {
// Stuff to do when the mouse leaves the element
$(this).removeClass('active');
// Other styles you want to remove here
// ...
});
});
Edit:
As I found out, jQuery .hover() function DO accept single handler. In that case, you'll have to let the class toggle inside:
$(document.ready(function(){
$('nav ul li').hover(function() {
// Stuff to do when the mouse enters the element
$(this).toggleClass('active');
});
});

jQuery: Clicking anywhere to remove class, without using $('body').on('click'

I want to remove all active classes when clicking anywhere on the screen, but if a clicked element has the .dropdown class, I would also want to toggle the .active class into that element.
// remove all .active classes when clicked anywhere
hide = true;
$('body').on("click", function () {
if (hide) $('.dropdown').removeClass('active');
hide = true;
});
// add and remove .active
$('body').on('click', '.dropdown', function () {
var self = $(this);
if (self.hasClass('active')) {
$('.dropdown').removeClass('active');
return false;
}
$('.dropdown').removeClass('active');
self.toggleClass('active');
hide = false;
});
I have this working with the above but I'm worried capturing a body click is overkill, and unnecessary. Is there a better solution?
jsiddle - I've set several li's to the .active class, if you click around you will see they get removed. Clicking an li will trigger toggleClass('active'), whilst still removing all .active classes.

you could try doing:
$('body').on("click", function (ev) {
if( $(ev.target).hasClass('.dropdown') ) {
//you clicked on .dropdown element, do something
}
else {
//you clicked somewhere other than dropdown element
}
});

How to prevent assigning click event on child items?

I made an click event for .menu li which has ul in it using $(".menu li:has(ul)"). It works but it also assigns the same event to .menu li ul li. I tried using e.stopPropagation();, e.PreventDefault(); and return false; inside function but that didn't worked at all. How to prevent that?
Here's the fiddle to show up actual problem.
jQuery I used:
$(".menu li:has(ul)").click(function() {
console.log('has ul');
if($(this).children("ul").is(':visible')){
$(this).children("ul").slideUp();
}else{
$(this).children("ul").slideDown();
}
});

Try this instead:
$('.menu a').click(function() {
var next=$(this).next();
if(next.prop('tagName')=='UL') {
if(next.is(':visible')){
next.slideUp();
}else{
next.slideDown();
}
}
});

It's Works now Fiddle you need to add return false on child UL

Basic issue with jQuery Accordion

I am using a jQuery Accordion for my sidebar navigation. Currently I have 2 links which both have 'children' beneath them.
Here is my jsFiddle: http://jsfiddle.net/6Eh8C/
You'll notice that when you click 'About Us', the Gallery closes. This shouldn't happen. Gallery should only close when I click 'Gallery'.
How do I fix this?
Here is my jQuery:
jQuery(function($) {
$('#accordion > li > a').click(function (e) {
if ($(this).next('ul').length == 0) {
// link is for navigation, do not set up accordion here
return;
}
// link is for accordion pane
//remove all the "Over" class, so that the arrow reset to default
$('#accordion > li > a').not(this).each(function () {
if ($(this).attr('rel')!='') {
$(this).removeClass($(this).attr('rel') + 'Over');
}
$(this).siblings('ul').slideUp("slow");
});
//showhide the selected submenu
$(this).siblings('ul').slideToggle("slow");
//addremove Over class, so that the arrow pointing downup
$(this).toggleClass($(this).attr('rel') + 'Over');
e.preventDefault();
});
$('.slides_item').children('div').css('background','#ededed')
});
Many thanks for any pointers :-)

I think you just want to remove one line:
$('#accordion > li > a').not(this).each(function () {
if ($(this).attr('rel')!='') {
$(this).removeClass($(this).attr('rel') + 'Over');
}
// Remove this line, you don't want to slide up other uls.
// $(this).siblings('ul').slideUp("slow");
});

How to add a class onto the selected li element and make li full-sized-clickable

I want to add a class to the selected 'li' and at the same time, remove the class:selected from previous selected li element.
I have worked on it hours and still haven't got any luck. I also checked others questions, but their solutions don't work for me.
Help please....
<ul id='mainView' class='menu' style='float: left; clear: both;'>
<li>Patient</li>
<li>Recommendations</li>
</ul>
<script type="text/javascript">
$(document).ready(function () {
$('.menu ul a').on('click', function (event) {
$('.menu ul a.selected').className = '';
alert($(this).attr('id'));
$(this).attr('class') = 'selected';
});
});
// $('.menu li').on('click', function () {
// $('.menu li.selected').className = '';
// this.className = 'selected';
// });
</script>
Update:
I did put a inside li, but if I click on the li not the a inside of the li, the webpage does not redirect. That's the reason why I do it in a reversed way.
Update 2
The reason why the selected li does not get the "selected" class is because the whole webpage is redirected to a new page which has the same navigation bar.
So now the question is how to highlight the selected li(it was selected on the previous page) on the new webpage.

Inside an UL everybody (even a browser) is expecting to see a LI
so your HTML:
<ul>
<li>Patient</li>
<li>Recommendations</li>
</ul>
And your jQ:
$('ul li').click(function(){
$(this).addClass('selected').siblings().removeClass('selected');
});
Building web pages you should know how to treat LI elements. Simple, like dummy containers with minimal styling.
That means that you rather add a display:block ... float:left and other cool stuff to the <A> elements, than setting a padding there you go with your full-sized-clickable A elements.
Additionally (if you don't have time to play with CSS) to make a LI fully clickable use:
$('ul li').click(function(){
var goTo = $(this).find('a').attr('href');
window.location = goTo ;
// $(this).addClass('selected').siblings().removeClass('selected'); // than you don't need this :D
});
After the OP late edit - and to answer the question
After the pages refreshes to get which one is the active one use:
// ABSOLUTE PATH
var currentPage = window.location;
// RELATIVE PATH
// var currentPage = window.location.pathname;
$('li a[href="'+ currentPage +'"]').addClass('selected');

<script type="text/javascript">
$(document).ready(function () {
$('.menu ul a').on('click', function (event) {
$('.menu ul a.selected').removeClass('selected');
alert($(this).attr('id'));
$(this).addClass('selected')
});
});
</script>

Try addClass and removeClass, they're jQuery functions:
$(document).ready(function () {
$('.menu ul a').on('click', function (event) {
$('.menu ul a.selected').removeClass("selected");
$(this).addClass('selected');
});
});
