I have a very annoying problem, which might be a product of my poor knowledge of javascript and jQuery.
I have a list that uses recursion to enable a hierarchy-structure, it looks as follows
$(function (){
$('#foo').click(function() {
$(this).children('ul').slideToggle();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li id='foo'>A
<ul>
<li id='foo'>B
<ul>
<li>
Sub-sub
</li>
</ul>
</li>
</ul>
</li>
</ul>
I'm trying to accomplish a collapse function, so that when the user clicks on 'A' all the children elements collapses, and if she clicks the 'B' node all of 'B's children collapses. But however I try I always end up having all of the lists with id = 'foo' collapsing.
In my eyes, $(this).children('ul').slideToggle(); will collapse the children, since $(this) points to the list element clicked...?
Been at this for far to long now, would love some help!
Here you go... No change in HTML. But like other suggested, you need to have unique ID's
$(function (){
$('li').click(function(event) {
event.stopPropagation();
$(event.target).children('ul').slideToggle();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li id='foo'>A
<ul>
<li id='foo'>B
<ul>
<li>
Sub-sub
</li>
</ul>
</li>
</ul>
</li>
</ul>

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/
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>
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");
});
I have an unordered list that when clicked shows their children. I am trying to add the feature where when there are children shown from a parent and a sibling of that parent is clicked, the other children close while the new ones open. Here is what I have so far:
<ul class="list">
<li> <a>Categories</a>
<ul>
<li> <a>Parent</a>
<ul>
<li><a>Child</a>
</li>
<li><a>Child</a>
</li>
<li><a>Child</a>
</li>
</ul>
</li>
<li> <a>Parent</a>
<ul>
<li><a>Child</a>
</li>
<li><a>Child</a>
</li>
<li><a>Child</a>
</li>
</ul>
</li>
<li> <a>Parent</a>
<ul>
<li><a>Child</a>
</li>
<li><a>Child</a>
</li>
<li><a>Child</a>
</li>
</ul>
</li>
<li> <a>Parent</a>
<ul>
<li><a>Child</a>
</li>
<li><a>Child</a>
</li>
<li><a>Child</a>
</li>
</ul>
</li>
</ul>
</li>
</ul>
This is my jquery:
$(document).ready(function(){
$('.list > li a').click(function(){
$(this).parent().children('ul').toggle();
});
Here is a jfiddle: https://jsfiddle.net/hmsvox5a/
Now if you click parent, the children show up. If you click another parent, its children appear as well. This leaves two sets of children open. I am trying to get the first set of children to close when I open the second. When I try to hide the siblings children, It messes up the whole jquery. Any ideas?
I'm not going to lie and tell you that this will scale or that it isn't awful, but this was the first thing I thought of off the top of my head. There are many ways to solve this.
$(document).ready(function(){
$('.list > li a').click(function(){
$('.open').parent().children('ul').toggle();
$('.open').removeClass('open');
$(this).addClass('open').parent().children('ul').toggle();
});
});
I believe what you want is this perhaps?
$(document).ready(function(){
$('.list > li a').click(function(){
$(this).parent('li').siblings('li').children('ul').hide();
$(this).siblings('ul').toggle().children().show();
});
});
test it out here: http://jsfiddle.net/vgwrqr6c/
I prefer to use CSS on the children to show items when its parent is shown. Then this efficient script works.
It keeps a reference to the last selected parent so it doesn't have to search the whole dom.
$(document).ready(function(){
var $selected;
$('.list > li a').click(function(){
if($selected){
$selected.remove class("open");
}
$selected = $(this).parent();
$selected.add class("open");
});
});
CSS would be something like this.
li ul{ display:none;}
li.open ul{ display: block}
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

$('#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());
});
}
});
