Remove and re-add Class Attribute inside a <div> unordered list item

This is the answer as i was able to solve.
Wanted to change the css class="jsTree-clicked" after the button click event happened from Hyperlink1 to Hyperlink3.
$(document).ready(function () {
//remove Class
$('#myJSTree').find('.jsTree-clicked').removeClass('jsTree-clicked');
//need to do add it to List Item which has Id =3
//check the list item which has id =3 if so add the class to it
// It is not a button click event.
$('#myJSTree li').each(function (i, li) {
console.log('<li> id =' + $(li).attr('id'));
var myIdVal = $(li).attr('id');
if (myIdVal == 3) {
$(this).addClass('jsTree-clicked');
}
});
});
.jsTree-clicked { background-color:red;}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="myJSTree">
<ul class="nav nav-list">
<li id="1">
<a class="jsTree-clicked" title="Hyperlink1">HyperLink1</a>
</li>
<li id="2">
<a title="Hyperlink2">HyperLink2</a>
</li>
<li id="3">
<a title="Hyperlink3">HyperLink3</a>
</li>
</ul>
</div>
When the Hyperlink is clicked the JsTree adds a class="jsTree-clicked" . When you navigate to a different node it will remove and re-add the same class to the navigated node.
Expected
I want a function to remove [class="jsTree-clicked"] for the given List Item based on ID inside the div.
AND
Re-add [class="jsTree-clicked"] to any ListItem by passing the Key i.e ID .
I hope I was able to explain my problem.
Thank you
My JSTree is a third party open source.

$('.nav-list').on('click', 'li', function() {
$('.nav-list li.active').removeClass('active');
$(this).addClass('active');
});
.active{
background-color:red;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="myJSTree">
<ul class="nav nav-list">
<li id="1">
<a title="Hyperlink1">HyperLink1</a>
</li>
<li id="2">
<a title="Hyperlink2">HyperLink2</a>
</li>
<li id="3">
<a title="Hyperlink3">HyperLink3</a>
</li>
</ul>
</div>

Maybe this is helpful to you?
$(function () { $('#myJSTree').jstree(); });
const toggle = (e) => {
if (+$("#test").val()>=10 ) {
e.target.classList.remove("jstree-clicked");
console.log("You entered an invalid number.")
}
console.log(e.target)
}

I have simply included a rudimentary toggle() function to demonstrate the point of removing and ading the class name "jsTree-clicked". Please note that JStree assigns other classes to the node dynamically that should be kept there.
It appears to me as if the class jstree-clicked (not: jsTree-clicked) is set by JSTree after an element was clicked. You might have to play aroud with this further to get what you want.
The following might be more what you want. It will "link" to the given href only when the predefined test criteria in checkinput() is met:
$(function () { $('#myJSTree').jstree(); });
const checkinput = (e) => {
if (+$("#test").val()>=10 ) {
console.log("You entered an invalid number.")
} else document.location.href=e.target.href;
}

</li>
</ul>

<input type="text" value="3" id="test"> < 10<br>
HyperLink1 will link to the page "user1" if the input is valid, <br>otherwise an eror will be shown in the console.

I want to make a parent nav link sidebar active when its child is active (current page)

Here's my code:
I want it in a way that when i click on a child link, it becomes active and the parent link is active too. I utilize the css class .active for my active classes for both the main and sub-menu.
The below JS snippet works but only for the menus without sub-menus
$(document).ready(function($) {
var url = window.location.href;
var activePage = url;
$('.menu li a').each(function() {
var linkPage = this.href;
if (activePage == linkPage) {
$(this).closest("li").addClass("active");
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="menu">
<ul class="list">
<li class="header">MAIN NAVIGATION</li>
<li class="">
<a href="index.php">
<i class="material-icons">home</i>
<span>Dashboard</span>
</a>
</li>
<li>
<a href="sell.php">
<i class="material-icons">receipt</i>
<span>Sell</span>
</a>
</li>
<li>
<a href="#">
<i class="material-icons">show_chart</i>
<span>Reporting</span>
</a>
</li>
<li>
<a href="javascript:void(0);" class="menu-toggle">
<i class="material-icons">apps</i>
<span>Products</span>
</a>
<ul class="ml-menu">
<li>
Add Product
</li>
<li>
All Products
</li>
<li>
Add Category
</li>
<li>
All Categories
</li>
</ul>
</li>
</ul>
</div>
<!-- #Menu -->

Implement an on mousedown event listener for your anchor tags, passing in the id for each anchor tag and use the parentElement property to get the element's parent.
document.getElementById("myLI").parentElement.nodeName;

you can try this JS code:
$(document).ready(function () {
$('a').click(function () {
//removing the previous selected menu state
$('.menu').find('li.active').removeClass('active');
//adding the state for this parent menu
$(this).parents("li").addClass('active');
});
});
And the css for Active link:
.active > a {
color:red;
}
hope it helps...

Need an element's parent index using jquery or javascript

I have three <ul>s that expand when their buttons are clicked. Not all three <ul>s will show up - only when there is a notification to show. I hard-coded the values for now, but I can instantiate them on an as-needed basis.
Right now, they cover each other when they expand. I would like the others to move when a list is expanded so they don't cover each other. I was thinking of getting the index of the one whose button is clicked and then resetting the bottom style of the others. I need to get the index of the <ul> parent of the button that was clicked, probably using jQuery but straight JavaScript is fine as well. Can anyone help?
Here is my code:
<div id="NotificationDiv">
<ul id="noticeLead" class="notification_base notification_Lead"><button id="notification_button">Lead Notice</button>
<div>
<li id="urlLead" class="notification_urlNotice notification_notice">
<a target="_blank" >Check Lead #1</a>
</li>
<li id="urlLead" class="notification_urlNotice notification_notice">
<a target="_blank" >Check Lead #2</a>
</li>
</div>
</ul>
<ul id="noticeTask" class="notification_base notification_Task"><button id="notification_button">Task Notice</button>
<div>
<li id="urlTask" class="notification_urlNotice notification_notice">
<a target="_blank" >Check Task #5</a>
</li>
<li id="urlTask" class="notification_urlNotice notification_notice">
<a target="_blank" >Check Task #6</a>
</li>
<div>
</ul>
<ul id="noticePolicy" class="notification_base notification_Policy"><button id="notification_button">Policy Notice</button>
<div>
<li id="urlPolicy" class="notification_urlNotice notification_notice">
<a target="_blank" >Check Policy #3</a>
</li>
<li id="urlPolicy" class="notification_urlNotice notification_notice">
<a target="_blank" >Check Policy #4</a>
</li>
</div>
</ul>
</div>
And in the $(document).ready, I have:
$('.notification_base').on('click', 'button', function(){
$(this).closest('.notification_base').find('.notification_urlNotice').slideToggle();
});

Try this:
var myParentId; //Here you'll store the id of the clicked element
$('.notification_base').on('click', 'button', function(){
$(this).closest('.notification_base').find('.notification_urlNotice').slideToggle();
myParentId = $(this).attr("id");
});

Thank you everyone for your input. I changed my structure to a table assigning .parent class to the header row and .child class to the data row and put this code in the jQuery ready function and it works great.
function getChildren($row) {
var children = [];
while($row.next().hasClass('child')) {
children.push($row.next());
$row = $row.next();
}
return children;
}
$('.parent').on('click', function() {
var children = getChildren($(this));
$.each(children, function() {
$(this).toggle();
})
});

On hover closing specific list element

<ul class="open-close1" id="reportType">
<li class="active">
<div id="subcats">
<ul>
<li>
<img class="loading-spinner" src="store/$vendorSettingsDTO.vendorId/assets/themes/$vendorSettingsDTO.skinname/images/loading.gif" height="18"/>
</li>
</ul>
</div>
</li>
</ul>
<script>
jQuery(document).ready(function($){
jQuery.getJSON('subcat.ajx?vid=$vendorSettingsDTO.vendorId&cid=$catid', function(data) {
//Render subcatergories using Mustache.js (https://github.com/janl/mustache.js)
var subcat_mustache =
'<ul>\
<a style="font-size:14px; font-weight:bold; color:#0073B3;" class="opener"href="{{URL}}">{{description}}</a>\
{{#childs}}\
{{> child}}\
{{/childs}}\
</ul>';
var partials = {
child:
'<li>\
<a class="opener" href="{{URL}}">{{description}}</a>\
<div class="subnav1 hidden">\
<ul>\
{{#childs}}\
{{> child}}\
{{/childs}}\
</ul>\
</div>\
</li>'
}
jQuery("#subcats").html(Mustache.render(subcat_mustache, data, partials));
});
});
</script>
<script>
$(document).ready(function() {
$(".open-close1").hover(function (){
//$(this).children('.subnav1').toggle();
//console.log("$(this).children('.subnav1') "+$(this).children('.subnav1'));
//$(".subnav1", this).toggle();
$(this).find('.subnav1').toggle(); // p00f
});
});
</script>
This is the code I have in case of my category page. I implemented a logic to toggle the block on hover. But entire list of categories is toggling instead of specific list on which it is hovered.
Please help me its IRRITATING me. Thanks a lot for your help in advance.

I assume your rendered html like below;
<ul class="open-close1" id="reportType">
<li class="active">
<div id="subcats">
<ul>
<li>
<a class="opener" href="#">Item1</a>
<div class="subnav1 hidden">
<ul>
<li>Item1-1</li>
<li>Item1-2</li>
<li>Item1-3</li>
</ul>
</div>
</li>
<li>
<a class="opener" href="#">Item2</a>
<div class="subnav1 hidden">
<ul>
<li>Item2-1</li>
<li>Item2-2</li>
<li>Item2-3</li>
</ul>
</div>
</li>
<li>
<a class="opener" href="#">Item3</a>
<div class="subnav1 hidden">
<ul>
<li>Item3-1</li>
<li>Item3-2</li>
<li>Item3-3</li>
</ul>
</div>
</li>
</ul>
</div>
</div>
</li>
</ul>
You can use following js for above html structure;
$(".opener").hover(function (){
$(this).next().toggle();
});
Here is a working demo: http://jsfiddle.net/cubuzoa/EKu2q/
Edit: On your site, category section you mentioned loaded with ajax. So you need to run function after ajax load like below;
<script>
jQuery(document).ready(function($){
jQuery.getJSON('subcat.ajx?vid=$vendorSettingsDTO.vendorId&cid=$catid', function(data) {
//Render subcatergories using Mustache.js (https://github.com/janl/mustache.js)
var subcat_mustache =
'<ul>\
<a style="font-size:14px; font-weight:bold; color:#0073B3;" class="opener"href="{{URL}}">{{description}}</a>\
{{#childs}}\
{{> child}}\
{{/childs}}\
</ul>';
var partials = {
child:
'<li>\
<a class="opener" href="{{URL}}">{{description}}</a>\
<div class="subnav1 hidden">\
<ul>\
{{#childs}}\
{{> child}}\
{{/childs}}\
</ul>\
</div>\
</li>'
}
jQuery("#subcats").html(Mustache.render(subcat_mustache, data, partials));
$(".opener-parent").parent('li').hover(function (){
$(this).find('subnav1').toggle();
});
});
});
</script>
I have also give class name for upper categories as opener-parent and updated js code
Updated demo: http://jsfiddle.net/R9KLz/4/
Final Result: If you do not want to add opener-parent class, you can use following;
$("#subcats ul li").hover(function (){
if ($(this).find('.subnav1').first().find("ul").has("li").length) {
$(this).find('.subnav1').first().toggle();
}
});
Here is a working demo: http://jsfiddle.net/cubuzoa/R9KLz/5/

Something I noticed, I think you have an extra <div> in your list markup.
<ul class="open-close1" id="reportType">
<li class="active">
<div id="subcats">
<ul>
<li><img class="loading-spinner" src="store/$vendorSettingsDTO.vendorId/assets/themes/$vendorSettingsDTO.skinname/images/loading.gif" height="18"/></li>
</ul>
</div>
<!--</div>-->
</li>
</ul>
Also, I just a hunch, but I think you need to be more specific in which element inside of your class you want to talk to. For example, you have this:
$(this).find('.subnav1').toggle();
But I think you need something more along the lines of:
$(this).find('.subnav1 ul').toggle();
Or, if possible, you could give your list(s) some sort of hook to make it even easier to talk to.

How to add a submenu after X number of <li> with Javascript or Jquery?

I have in HTML
<div class="ktmsg">
<ul>
<li class="a1">
<a title="Link Tools" href="#"> … </a>
</li>
<li class="a2">
<a title="Link Tools" href="#"> … </a>
</li>
<li class="a3">
<a title="Link Tools" href="#"> … </a>
</li>
</ul>
</div>
What i want to do is to add after the second </li> an <ul>More</ul>
Final expected output should be
<div class="ktmsg">
<ul>
<li class="a1">
<a title="Link Tools" href="#"> … </a>
</li>
<li class="a2">
<a title="Link Tools" href="#"> … </a>
</li>
<ul> //Starting the sub-menu
More // The link that after i hover it will start showing the <li> starting from the third one
<li class="a3">
<a title="Link Tools" href="#"> … </a>
</li>
</ul>
</ul>
</div>
I am thinking that the javascript would look smth like this:
limenu = document.selectAll(.ktmsg)('<li>');
for(var i=1, i<2, i++)
remove.limenu
add.
.... And i am quite stuck, Please help, would be much appreciated.

Using jQuery
jQuery(function ($) {
var $lis = $('.ktmsg > ul > li');
var $a = $('<li>More</li>').insertAfter($lis.eq(1));
var $lefts = $lis.slice(2).hide();
$a.hover(function () {
clearTimeout($a.data('hoverTimer'));
$lefts.show();
}, function () {
var timer = setTimeout(function () {
$lefts.hide();
}, 200);
$a.data('hoverTimer', timer);
});
$lefts.hover(function () {
clearTimeout($a.data('hoverTimer'));
}, function () {
var timer = setTimeout(function () {
$lefts.hide();
}, 200);
$a.data('hoverTimer', timer);
});
})
Demo: Fiddle

With jQuery to add this:
<ul>More</ul>
after second li you need:
$( 'li:eq(1)' ).after( '<ul>More</ul>' );

I've created a fiddle of how this could work using jQuery. Pretty simple really, you just hide the sub menu using CSS and then show/hide it as needed using jQuery when "More" is being hovered over. I've used fadeIn() and fadeOut() but you could just as easily use hide() and show() if you don't need the animations. I've restructured your HTML slightly so if you use my solution use my new HTML.
