i have an issue to toggleclass for just children element.
<ul class="sample-menu">
<li id="sample-topmenu_2">
Menu Text
<ul class="sample-submenu">
<li class="submenu">Submenu Text</li>
<li class="submenu">Submenu Text</li>
</ul>
</li>
<li id="sample-topmenu_3">
Menu Text2
<ul class="sample-submenu">
<li class="submenu">Submenu Text2</li>
<li class="submenu">Submenu Text2</li>
</ul>
</li>
i use this jquery toggle, but it's toggle all li elements for all menu.
$( "*[id^=bga-topmenu_] p" ).click(function() {
$("li.submenu").toggleClass( "sumenu_show" );
});
I appreciate your help.
Try:
$( "*[id^=bga-topmenu_]" ).click(function() {
$(this).find("li.submenu").toggleClass( "sumenu_show" );
});
You can use $(this) to get the current context (i.e. the clicked element) and then find all <li> elements with the submenu class within that context, using the .find() method.

I have a selector as follows.
subMenus.children("li.tab").children("a").each(function () { ... }
It works as supposed to. Then, I read on the website that the following is also supposed to work (and since it's more compact, I prefer it that way).
subMenus.children("li.tab>a").each(function () { ... }
However, the latter seems not to find any elements as the action in the squiglies doesn't execute. What am I missing?
Edit
Markup as requested.
<ul id="submenu1" class="tabs tabs-transparent">
<li class="tab">A</li>
<li class="tab">B</li>
</ul>
<ul id="submenu2" class="tabs tabs-transparent">
<li class="tab">A</li>
<li class="tab">B</li>
</ul>
<ul id="submenu3" class="tabs tabs-transparent">
<li class="tab">A</li>
<li class="tab">B</li>
</ul>
A child combinator in CSS is the "greater than" symbol, it looks like this:
ol > li {
color: red;
}
It means "select elements that are direct descendants only". In this case: "select list items that are direct descendants of an ordered list". To illustrate:
<ol>
<li>WILL be selected</li>
<li>WILL be selected</li>
<ul>
<li>Will NOT be selected</li>
<li>Will NOT be selected</li>
</ul>
<li>WILL be selected</li>
</ol>
Try removing the > symbol.
$("li.tab a");
The first jQuery selector is looking for children of your <li/> (including grandchildren).
$("li.tab").children("a");
Whereas your second jQuery selector is looking for direct children of your <li/> (NOT including grandchildren).
$("li.tab > a");
Update:
You'll want to use .find instead of .children because
The .children() method differs from .find() in that .children() only
travels a single level down the DOM tree while .find() can traverse
down multiple levels to select descendant elements (grandchildren,
etc.) as well.
Source: https://api.jquery.com/children/
Try find().
Technically "li.tab > a" is not a "child" of subMenus
$(".tabs").find("li.tab>a").each(function () { console.log(this); });
<ul id="submenu1" class="tabs tabs-transparent">
<li class="tab">A</li>
<li class="tab">B</li>
</ul>
<ul id="submenu2" class="tabs tabs-transparent">
<li class="tab">A</li>
<li class="tab">B</li>
</ul>
<ul id="submenu3" class="tabs tabs-transparent">
<li class="tab">A</li>
<li class="tab">B</li>
</ul>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
.children() would only select direct children. So subMenus.children("li.tab>a") would select anchor tags that are direct children of subMenus, and also direct children of li.tab.
Here you can use .find() instead: subMenus.find(">li.tab>a").each()
Try this
subMenus.children("li.tab>a").each(function () { ... }
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 toggle tree which responds on click i.e. show or hide UL>li. I want to hide all the UL --> li who has parent ul-li. To make it more obvious I have apply css background-color to red which I want to be hidden by when page loads but show when it click back.

If I understood your question correctly, this is what you want:
$(".treeview").find('ul').hide()
Place this in your $(document).ready function and it'll hide the underlying unordered list upon page load.
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
