I'm trying to change the 'active' class for the clicked list item but I'm missing something. Here is what my HTML and jquery look like:
HTML
<ul class="additional-menu">
<li class="active"> Link1</li>
<li>Link2</li>
<li>Link3</li>
</ul>
jQuery
$("#link2").click(function(){
if ($(this).find('#additional-menu li').hasClass('active')) {
//console.log("Active class seen");
$(this).find('#additional-menu li').removeClass('active');
$(this).addClass('active');
}
});
Any idea what I'm missing? I'm not even detecting the active class at this point...
You could minimize your code to just
$('.additional-menu').on('click','li', function(){
$(this).addClass('active').siblings().removeClass('active');
});
Demo at http://jsfiddle.net/DvHBp/
There are many problems in the code
//from what i can understand you need to change the active class to the clicked li element not just the link2 element
$("#link2").click(function(){
// additional-menu is not an id it is a class and it is not a descendant of the li element
if ($(this).find('#additional-menu li').hasClass('active')) {
//console.log("Active class seen");
$(this).find('#additional-menu li').removeClass('active');
//if you are using a if statement then addClass should be outside the if block
$(this).addClass('active');
}
});
try
jQuery(function(){
var $lis = $('.additional-menu > li').click(function(){
$lis.removeClass('active');
$(this).addClass('active')
});
})
find() get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.
You should use
$(this).parent().siblings('#additional-menu li')
because in your html structure #link2 a tag has no descendant of #additional-menu li
You can make something very generic:
<ul class="additional-menu">
<li class="active"> Link1</li>
<li>Link2</li>
<li>Link3</li>
</ul>
And using this JavaScript:
$(function(){
$('.additional-menu > li').click(function(){
$('.additional-menu > li').removeClass('active');
$(this).addClass('active');
});
});
Try this solution :
HTML:
<ul class="additional-menu">
<li><a id="link1" href="link1"> Link1</a></li>
<li>Link2</li>
<li>Link3</li>
</ul>
CSS:
.active{
background-color : red;
}
jQuery:
//on first time load set the home menu item active
$(".additional-menu a#link1").addClass("active");
//on click remove active class from all li's and add it to the clicked li
$("a").click(function(){
$("a").removeClass("active");
$(this).addClass("active");
});

I have this code
<script>
$("li").hover(
function () {
$(this).addClass('active');
},
function () {
$(this).removeClass('active');
}
);
</script>
In order to add class active to my li in a menu.
<ul class="list-first-level">
<div about="" typeof="" class="ds-1col entity entity-paragraphs-item paragraphs-item-modulo-de-enlaces-item view-mode-modulo_de_enlaces_01_d clearfix">
<li id="elm" class="active always">
Undergraduate programmes
<ul>
<li>
Law
</li>
</ul>
</li>
</div>
</ul>
I need to not remove the active class after Im not hover on the element.
Just use this:
$("li").hover(function(){
$(this).addClass("active");
});
Although, you will end up with many active LI and does not provide a good UX.
When you hover over an element, remove the 'active' class from all li elements then add it back to the current element. This still means that if the user moves away from the last, hovered element - that element will remain in an 'active' state.
<script type="text/javascript">
$("li").hover(
function () {
$("li").removeClass('active');
$(this).addClass('active');
}
);
</script>
I want to add a specific class to next parent element (li) of link. For example I have active class on 'Home" tab but same time I also need 'new-class' to 'About' li.
Here is my markup
This is working for static class but when active class on link added dynamically, This is not working.
I tried this but not able to make working
$('li a').click(function() {
if ($(this).hasClass('active')) {
$(this).parent().next().addClass('active');
}
else{
$(this).parent().next().removeClass('active');
}
});
<ul>
<li><a class="active" href="">Home</a></li>
<li class="new-class">About</li>
<li>Service</li>
<li>Portfolio</li>
<li>Contact</li>
</ul>
I think this is what you want :
$('li a').click(function(e) {
e.preventDefault();
$(this).closest('ul').find('a.active').removeClass('active');
$(this).closest('ul').find('li.new-class').removeClass('new-class');
$(this).addClass('active');
$(this).parent().next().addClass('new-class');
});
.active{ color:red; }
.new-class a { color:blue; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li><a class="active" href="">Home</a></li>
<li class="new-class">About</li>
<li>Service</li>
<li>Portfolio</li>
<li>Contact</li>
</ul>
There is next() function
$(this).parent().next().addClass('active');
However this is not what you looking for. This adds a class to li. If you want to add the class to a inside that , you need
$(this).parent().next().find("a").addClass('active');
$(this).parent().next().addClass('active');
This will first get to the li of the anchor being clicked.
Then, it will select the next element in order which be the 2nd li in case the first li is clicked and then, we add the class to that element.
If I understand you correctly (on clicking a having class active add class new-class to subsequent li?), this should work:
$('.tab a').click(function() {
if ($(this).hasClass('active')) {
$(this).parent().next().addClass('new-class');
} else{
$(this).parent().next().removeClass('new-class');
}
});
$(document).on('click', '#ul li:not(.info)', function(){
alert();
});
My html is like this
<ul id="ul">
<li></li>
<li><a href="#" class="info"></li>
</ul>
why it still trigger when I click on .info?
Because your HTML defines .info class on the <a> descendant instead of the <li> itself, while your selector denotes :not(.info) which means the <li> is not having the .info class.
Try this instead:
$(document).on('click', '#ul li:not(:has(.info))', function(){
alert();
});
Alternatively, you can simply move your .info class to the <li> itself:
<li class="info"><a href="#"></li>
See jQuery's has and Fiddle
can you make it this and try
$(document).on('click', '#ul li a:not(.info)', function(){
alert();
});
#ul li:not(.info) looks for a class in li that is not info
#ul li a:not(.info) will give you the right result

I'm working with the off-canvas script from Foundation and it isn't working out of the box (of course) when I try to use the submenu options. I realized it wasn't adding a class (move-right) to the ul's of the li's in the off-canvas navigation. So I wrote a script to add that class which can be found here:
jQuery(document).ready(function() {
jQuery('ul.off-canvas-list li a').click(function() {
jQuery('ul.off-canvas-list li ul.left-submenu').addClass('move-right');
});
});
And here is how my HTML is structured:
<ul class="off-canvas-list">
<li class="has-submenu">Name 1
<ul class="left-submenu">
<li class="back">Back</li>
<li><a href="#"></li>
<li><a href="#"></li>
</ul>
</li>
<li class="has-submenu">Name 2
<ul class="left-submenu">
<li class="back">Back</li>
<li><a href="#"></li>
<li><a href="#"></li>
</ul>
</li>
<li class="has-submenu">Name 3
<ul class="left-submenu">
<li class="back">Back</li>
<li><a href="#"></li>
<li><a href="#"></li>
</ul>
</li>
...etc
</ul>
My problem is that my script is adding the class to ALL ul.left-submenu's instead of just the one directly under the li that I click on. I can't figure out how to add the class 'move-right' to only the 'ul.left-submenu' child of the parents li that I clicked on and remove the 'move-right' class from the other 'ul.left-submenu'
I thought maybe using the sibling() selector, but I wasn't quite sure how to implement that into my script. Any and all help is greatly appreciated.
Another issue has arose and that is being able to close the opened "ul.left-submenu" by clicking on the "Back" which comes before the other li's in each ul.left-submenu. I updated the HTML above to include the "" and also have provided the script below that I tried using that hasn't worked.
jQuery('li.back').on('click', function() {
console.log('close submenu');
jQuery('ul.left-submenu').removeClass('move-right');
});
The target element is the grandparent of the clicked element so you can use the closest method:
$('ul.off-canvas-list li a').click(function() {
$('.move-right').removeClass('move-right');
$(this).closest('ul.left-submenu').addClass('move-right');
});
you can add it directly to the clicked element by using this
jQuery(document).ready(function() {
jQuery('.left-submenu li a').click(function() {
jQuery('.left-submenu').removeClass('move-right'); // remove class move-right from every elements with class left-submenu
jQuery(this).parents('.left-submenu').addClass('move-right'); // add class move-right to the parent with class left-submenu of current element
});
});
Edit:
if in your updated code, you want to click only by a right after .has-submenu, you need this probably, so it didn't trigger on click for a inside .left-submenu
jQuery(document).ready(function() {
jQuery('.has-submenu > a').click(function() {
jQuery('.left-submenu').removeClass('move-right'); // remove class move-right from every elements with class left-submenu
jQuery(this).children('.left-submenu').addClass('move-right'); // add class move-right to the children with class left-submenu of current element
});
});
sorry for my mistakes not looking again for the code before posting it, because ul.left-submenu is in the same position with a and not it's children, you need to use .siblings to get ul.left-submenu, so change the code to this
jQuery(document).ready(function() {
jQuery('.has-submenu > a').click(function() {
jQuery('.left-submenu').removeClass('move-right');
jQuery(this).siblings('.left-submenu').addClass('move-right');
});
});
here's the working Example in Fiddle
Ok, so you want to add a class move-right to the ul.left-submenu that is directly under the has-submenu li that you clicked, right?
So:
$(document).ready(function() {
//Trigger the click only on the li's has-submenu
$('li.has-submenu').on('click', function() {
//Remove the class from other ul, if there's any
$('ul.left-submenu').removeClass('move-right');
//Finds the direct ul child using the '>' selector, and adds the class.
$(this).find('> ul.left-submenu').addClass('move-right');
});
});
The way you have your selector it targets all the ul.left-submenu elements you have, another way to target just the element clicked would be like this:
$('.off-canvas-list').on('click', 'ul.off-canvas-list li a', function (){
$('.move-right').removeClass('move-right');
$(event.target).closest('ul.left-submenu').addClass('move-right');
});
Your selector is too broad. If what you want to do is to add move-right to left-submenu when you click has-submenu, that's what you need to do:
$('.has-submenu').click(function() {
$(this).find($('.left-submenu')).addClass('move-right');
});
Fiddle: http://jsfiddle.net/x9zcav0p/
If you need to reset move-right, do this:
$('.has-submenu').click(function() {
$('.move-right').removeClass('move-right');
$(this).find($('.left-submenu')).addClass('move-right');
});
Fiddle: http://jsfiddle.net/x9zcav0p/1/
Updated markup:
For your updated markup, you can target the next() element after the anchor tag:
$('.has-submenu > a').on('click', function() {
$('.move-right').removeClass('move-right');
$(this).next().addClass('move-right');
});

I am a newbie in web development. Not sure if it is a dumb question.
<nav class="navigation">
<ul class="navigation-items-container">
<li class="navigation-items">Home</li>
<li class="navigation-items">about</li>
<li class="navigation-items">blog</li>
<li class="navigation-items">contacts</li>
</ul>
/nav>
On hover of each li I want to know its in which children Number of ul.
i.e
On hovering "Home" it should give as children Number 0 and on hovering "blog" it should give children number 2.
As you've included the jQuery tag I'll post a jQuery based answer - if you want a non-jQuery answer let me know:
$(".navigation-items-container li").hover(function(e) {
var index = $(this).index();
});
And FYI your markup is wrong, the anchors should be inside the li tags
The version for your current code (though it should be changed):
$(".navigation-items-container a").hover(function(e) {
var index = $(this).index();
});
Due to the fact that your li elements are within a elements, you should use this:
$(".navigation li").hover(function(){
var index = $(".navigation li").index(this);
alert(index);
});
Here is a working example
Of course, it would be better to have your a elements with the li elements like so:
<li class="navigation-items">Home</li>
That way the li elements will be direct children of the ul element, then you could do this:
$(".navigation li").hover(function(){
var index = $(this).index();
alert(index);
});
Here is a better example
Alternatively, and I am not saying this is better, but you could also use data-* attributes to store the value you want:
<li class="navigation-items" data-myindex="0">Home</li>
with this:
$(".navigation li").hover(function(){
var index = $(this).data("myindex");
alert(index);
});
This has the benefit that you could specify different values if required, such as record IDs for example.
Here is an example
Try this.
$('li').on('mouseover', function(){
console.log($('ul li').index($(this)));
})
Try index()
http://api.jquery.com/index/
$(".navigation ul li").hover(function(e) {
alert($(this).index());
});
More possiblities
this help you
Working Demo http://jsfiddle.net/cse_tushar/7SmfR/
$(".navigation ul li").hover(function() {
alert($(this).index('li'));
});
Correct your markup anchor(a) tag should be enclosed within li tags
<nav class="navigation">
<ul class="navigation-items-container">
<li class="navigation-items">
Home
</li>
<li class="navigation-items">
about
</li>
<li class="navigation-items">
blog
</li>
<li class="navigation-items">
contacts
</li>
</nav>
