Remove container when all children is dismissed - javascript

I am trying to remove the parent container when the children li are removed. Each li has a dismissal anchor that once it is clicked, the li is removed.
What I would like is for that when all the li are removed, the div container will also be removed.
I am currently using backbone.js
<div class="container>
<ul>
<li><a class="dismiss"></a></li>
<li><a class="dismiss"></a></li>
<li><a class="dismiss"></a></li>
</ul>
</div>
Thanks for your help!

$(document).on("click",".dismiss",function(e){
e.preventDefault();
$(this).parent("li").remove();
if(!$(".container ul li").length){
$(".container").remove();
}
});

How to add class to next parent li?

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');
}
});

Dropdown Menu Open width Jquery

I have a problem with a drop down menu that must remain open to the click.
After the menu is open, you can click the link inside and the menu item just clicked.
How can I do to remedy the preventDefault ?
Menu HTML:
<nav class="main-menu">
<ul id="" class="menu">
<li>
Menu One
<div class="sub-menu">
<ul>
<li>test test test</li>
... More links ...
</ul>
</div>
</li>
... More items ...
</ul>
</nav>
This is a portion of code
$('.main-menu li a').click(function(event) {
event.preventDefault();
$('.main-menu').find('.sub-menu').removeClass('open');
$(this).parent().find('.sub-menu').addClass('open');
});
An example is visible here JSFIDDLE
Just remove
$('.main-menu').find('.sub-menu').removeClass('open');
Here is a fiddle you can check out
Get rid of event.preventDefault();
Instead do like this
<a href="#" onclick="return false">
Then give each main menu a class name. And call the click event on that class.
https://jsfiddle.net/btevfik/9m9rufqx/3/
You can replace your selector with a more targeted (.menu > li > a) :
$('.menu > li > a').click(function(event) {
event.preventDefault();
$('.sub-menu.open').removeClass('open');
$(this).parent().find('.sub-menu').addClass('open');
});

How to Remove a Class from a Sibling of a Parent

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');
});

Add css class to parent li and sub li

I have a submenu like below:
<ul id="main-menu" class="" style="">
<li class="root-level has-sub">
Menu 1
<ul>
<li>Sub-menu 1</li>
<li>Sub-menu 2</li>
</ul>
</li>
<li>Menu 2</li>
<li class="root-level has-sub"> <!-- here -->
Menu 3
<ul>
<li class="root-level has-sub"> <!-- add class 'opened' here and -->
Sub-menu 3
<ul>
<li>Sub-sub-Menu 1</li> <!-- this -->
<li>Sub-sub-Menu 2</li> <!-- when user click this or -->
</ul>
</li>
</ul>
</li>
What I would like to have is, when I click to the child, it will add 'opened' class to parent and highlight the clicked element. My code only success on Menu 1 and failed on Menu 3.
Notice that, in Menu 3, there are 2 parents for Sub-sub-Menu 1 and Sub-sub-Menu 2. So my question is, if i click on Sub-sub-Menu 1 or Sub-sub-Menu 2 it will highlight and add 'opened' class to 2 parents li above.
Note: I try to implement unlimited level of menu
Here is my full code Fiddle
I think you should use a different selector(for the click event). Look for all li>a pairs, corresponding to the submenu items, inside your #main-menu list
$('#main-menu li>a').click(function (e) {
e.preventDefault();
$('.active').removeClass('active');
$('.opened').removeClass('opened');
$(this).parent('li').addClass('active').parents('.root-level').addClass('opened');
//------------------------------------------------------^-----------------------------
// selects all parents with the 'root-level' class
});
Modifying the css to:
#main-menu .active {
background-color:#df0000;
color:#fff;
}
DEMO
you simply use the not: attribute in your closest() method to exclude all classes root-level
$(function () {
$('ul#main-menu li ul li').click(function (e) {
e.preventDefault();
//we search for the first ancestor of this which is a li
$(this).closest('li:not(".root-level")').addClass('active').siblings().removeClass('active');
$('.active:first').closest('ul').addClass('opened');
});
});
check the link http://jsfiddle.net/GEj4z/11/
If I understood correctly what was desired was being able to produce a menu like behavior and it is because of that I would like to present an alternate solution:
Sample Fiddle
$('#main-menu').on('click','li:not(.root-level)',function(e){
$('.parent').removeClass('parent');
$('.selected').removeClass('selected');
$(this).parents('li.root-level').children('a').addClass('parent');
$(this).children('a').addClass('selected');
});
In this solution the parent menus are highlighted and the clicked item is marked as selected again I wanted to share my POV of this problem. I hope it helps.
Inside your click event use $(this).parents('li') to get the top level parent li of the clicked element. I hope this helps.
I found the solution! my jquery is:
$(function () {
$('ul#main-menu li ul li').click(function (e) {
e.preventDefault();
$(this).closest('li:not(".root-level")').addClass('active').siblings().removeClass('active');
$(this).parents('li').addClass('opened');
$(this).closest('li:has(".root-level")').removeClass('active');
});
});

changing active class for list element

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");
});
