jQuery accordion slides up multiple times - javascript

I'm making a jquery accordion and I have some issues
My jQuery searches for a ul inside a class and if it has a certain class it slides down, but it slides down as many times as the element ul exists in the whole nav
Here is my jquery code so far:
if($(this).has("ul").length){
$(".menu ul li").on('click',function(e){
$(this).addClass('open').siblings().removeClass('open').children();
$('.menu ul li ul').slideUp();
if($(this).parents().find(".open").length){
$(this).children('ul').slideDown();
}
//$(this).parents().find(".open").children('ul').slideDown();
e.preventDefault();
});
};
this is my html:
<div class="menu">
<a id="jump" href="#"><p>Menu</p><span class="right">▼</span></a>
<nav class="row">
<div class="page_wrapper">
<ul class="niveau_1">
<li class="active">Home</li>
<li>Group
<ul class="sub-menu">
<li>QHSE/Awards</li>
<li>Vacatures/</li>
</ul>
</li>
<li>Nieuws & Media
<ul class="sub-menu">
<li>Van Moer in de media</li>
<li>Nieuwsarchief</li>
</ul>
</li>
<li>Sport & Events
<ul class="sub-menu">
<li>Casual Friday
<ul>
<li>Inschrijving</li>
<li>Foto's</li>
</ul>
</li>
<li>Thursday Lounge</li>
<li>Triatlon</li>
<li>Sponsoring</li>
<li>Beurzen</li>
<li>Kalender</li>
</ul>
</li>
<li>Vestigingen</li>
<li>Contact</li>
</ul>
</div>

just guessing sincei don't have HTML to look too... your problem is here in parents()
Get the ancestors of each element in the current set of matched elements, optionally filtered by a selector.
i think u need parent() here
Get the parent of each element in the current set of matched elements, optionally filtered by a selector.
if($(this).parent().find(".open").length){ //try this
$(this).children('ul').slideDown();
}
note: it would be easy if you provide us with your HTML too

Jquery show or hide children link if it is available

I have a question on Jquery. If I click on Link1, which does not have any ul.children and the class current_page_item will be added(not shown in this code as it will be added automatically by Wordpress), then ul.children in Link2 should be hidden.
If i click on Link 2, which will have both class page_item_has_children current_page_item, in this case ul.children should be shown. I have tried my code bellow, which is i know it is absolutely wrong. Please give me your advices. Many thanks.
if($(.navigation).hasClass(page_item_has_children)){
(.navigation .page_item_has_children .children).hide();
}else if( $(.navigation).hasClass(page_item_has_children) && $(.navigation).hasClass(current_page_item)){
(.navigation .page_item_has_children .children).show();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="navigation">
<li>Link1</li>
<li class="page_item_has_children current_page_item">Link2
<ul class="children">
<li class="page_item">Link3</li>
<li class="page_item ">Link4</li>
</ul>
</li>
</ul>
This solution is a bit more towards your scenario (edited based on comment):
$(".navigation li").on("click", function() {
if ($(this).hasClass("page_item_has_children") && $(this).hasClass("current_page_item")) {
$(".navigation .children").show();
} else {
$(".navigation .children").hide();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="navigation">
<li>Link1
</li>
<li class="page_item_has_children current_page_item links">Link2
<ul class="children">
<li class="page_item">Link3
</li>
<li class="page_item ">Link4
</li>
</ul>
</li>
</ul>
How about simply hiding all nested UL elements, then simply showing the children of the clicked one?
$(".navigation li").each(function() {
// When we first load, hide all nested menus.
$(this).children("ul").hide();
if (localStorage.menuNumber) {
$(".navigation li").eq(localStorage.menuNumber).children().show();
}
})
.on("click", function() {
// When any top-level ul is clicked, hide the
// nested menus then show the current one.
$(this).parent().children().find("ul").hide();
$(this).children().show();
// We also want to persist this selection,
// should the user refresh...
localStorage.menuNumber = $(this).index;
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="navigation">
<li>Link1
</li>
<li class="page_item_has_children current_page_item">Link2
<ul class="children">
<li class="page_item">Link3
</li>
<li class="page_item ">Link4
</li>
</ul>
</li>
</ul>
Edited it so that when it initially loads, all nested uls are hidden. Hope this helps! And edited again, to store the clicked menu in local storage. Sadly, for security reasons, this won't work here. See it as a fiddle: https://jsfiddle.net/snowMonkey/fnuvvLwb/

Slide up multiple <ul> elements using jQuery

I am trying to construct a jquery statement that will slideUp() all <ul> elements whose siblings don't contain a set of specific classes (.clicked, .chosen).
Suppose I have the following nested <ul> structure:
<ul class="mainmenu">
<li>Dogs</li>
<ul>
<li>Fido</li>
<li class="chosen">Barney</li>
<li>Turbo</li>
</ul>
<li>Cats</li>
<ul>
<li>Sylvester</li>
<li>Felix</li>
<li>Garfield</li>
</ul>
<li class="clicked">Hamsters</li>
<ul>
<li>Chubbs</li>
<li>Oreo</li>
<li>Ruby</li>
</ul>
</ul>
For the above example, I would like to slideUp() only the 'Cats' <ul> element ('Sylvester', 'Felix', 'Garfield') because none of it's elements use the 'chosen' or 'clicked' classes.
My current jquery statement reads:
$('.mainmenu').first().siblings().not('.clicked, .chosen').slideUp();
This, and everything else I have tried, returns nothing. Suggestions?
You HTML looks challenging :) but somehow, I've managed to create a query to perform what you're looking for.
And if you want to check multiple class for particular element you can use is() as well.
//Check li doesn't have clicked class and then filter ul next to the li
$('.mainmenu > li').not('.clicked').next('ul').filter(function(){
//Find the ul, if it's any of li doesn't have chosen class
if(!$(this).find('li').hasClass('chosen'))
{
return $(this);
}
}).slideUp();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="mainmenu">
<li>Dogs</li>
<ul>
<li>Fido</li>
<li class="chosen">Barney</li>
<li>Turbo</li>
</ul>
<li>Cats</li>
<ul>
<li>Sylvester</li>
<li>Felix</li>
<li>Garfield</li>
</ul>
<li class="clicked">Hamsters</li>
<ul>
<li>Chubbs</li>
<li>Oreo</li>
<li>Ruby</li>
</ul>
</ul>

Twin unordered lists

So i have this structure:
<ul>
<li class="paginator"><a class="active">1</a></li>
<li class="paginator"><a>2</a></li>
<li class="paginator"><a>3</a></li>
</ul>
... bunch of html code
<ul>
<li class="paginator"><a class="active">1</a></li>
<li class="paginator"><a>2</a></li>
<li class="paginator"><a>3</a></li>
</ul>
Which is an unordered anchor, every time the user clicks on an anchor it becomes of the active class. My question is: What's the best way to duplicate this effect on both anchors. So far, when i click on the anchor 2 of the bottom, it succesfully get the active class, but the anchor 2 of top doesn't. Is there a way to have something like twin or cloned elements?
You can get the index of the clicked li.paginator element, and set the active class to any other li.paginator with the same index using nth-child, that way the class gets added to both UL's
var lis = $('.paginator').on('click', function(e) {
e.preventDefault();
var idx = $(this).closest('li').index();
lis.find('a').removeClass('active');
lis.filter(':nth-child('+(idx+1)+')').find('a').addClass('active');
});
a {cursor : pointer}
a.active {
text-decoration: underline;
color: red!important;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li class="paginator"><a class="active">test 1</a></li>
<li class="paginator"><a>test 2</a></li>
<li class="paginator"><a>test 3</a></li>
</ul>
<!-- ... bunch of html code -->
<ul>
<li class="paginator"><a class="active">test 1</a></li>
<li class="paginator"><a>test 2</a></li>
<li class="paginator"><a>test 3</a></li>
</ul>
If you set it up like this is should work the same for both ul elements, unless you are wanting the elements to mirror each other:
$('.paginator').click(function(){ $(this).find('a').addClass("active") });

Finding Child of Parent Jquery

I am have a link in a li and when you click on it, it should open a ul, also contained in the li. I can't seem to get it to select the right element though. Code below
HTML
<ul>
<li>
hi
<ul>
<li class="hidden">more stuff</li>
</ul>
</li>
</ul>
CSS
.hidden{display:none;}
Js
$( "a" ).click(function() {
$(this).parent("li").children("ul").css("display","block");
});
Since the ul is the next sibling to the a, you'd use next to access it. Then you can look at the ul's children (children) or descendants (find) for the .hidden one and remove the class (removeClass):
$(this).next().children(".hidden").removeClass("hidden");
Live Example:
$("a").on("click", function() {
$(this).next().children(".hidden").removeClass("hidden");
return false;
});
.hidden {
display: none;
}
<ul>
<li>
one
<ul>
<li class="hidden">more stuff</li>
</ul>
</li>
<li>
two
<ul>
<li class="hidden">more stuff</li>
</ul>
</li>
<li>
three
<ul>
<li class="hidden">more stuff</li>
</ul>
</li>
</ul>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
In your code you are trying to make ul displayed although it is visible and it does not effect the li under it so you need to access that li like this. Removing the hidden class of the element to make it displayed is a better approach than assigning inline style as the commentators said
$(this).parent("li").children("ul").children("li").removeClass("hidden");
check here fiddler link...
hope it will help you....
$( "a" ).click(function() {
$(this).next().children(".hidden").removeClass("hidden");
});

click on li if no leaf node its append in another div

I have one Activity xml file and I am try to get from activity when click on activity there child display. Its look like end of the all click.
<ul id="firstLevelChild">
<ul id="ul">
<li id="4">Activities
<ul class="ul">
<li id="10066">Physical1
<ul class="ul">
<li id="10067">Cricket
<ul class="ul">
<li id="10068">One Day</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</ul>
Now I want that if li have no leaf node then its display in other another div. Something like:
Click on Acitivities there have child node Physical1 and there also child Cricket and there chil One Day now one day have no child when click on one day its display in my <div id="result"></div>
I would add this as a comment, but I don't have enough rep. ChildNodes() isn't a function - since it looks like you're using jQuery, try children() instead.
I think javascript could helpr you there. A part from the fact that you first build your DOM correct ;)
The hasChildNodes() method returns TRUE if the current element node has child nodes, and FALSE otherwise.
http://www.w3schools.com/dom/met_element_haschildnodes.asp
Assuming the markup you provided is how it's going to be always i.e. ul as child for all li. You just check if ul exists inside the current li. See fiddle
HTML
<div id="content">
<ul id="firstLevelChild">
<li>
<ul id="ul">
<li id="4">Activities
<ul class="ul">
<li id="10066">Physical1
<ul class="ul">
<li id="10067">Cricket
<ul class="ul">
<li id="10068">One Day</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
<h2>Result</h2>
<ul id="result"></ul>
JS
$('#content li').each(function (i) {
//for display purpose only
$('#content').append('<span class="list">li(' + i + '):' + $('ul', $(this)).length + '</span>');
//the code you needed
if ($('ul', $(this)).length < 1) {
$(this).on('click', function () {
$('#result').append($(this).parent().html());
});
}
});
