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;
}

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 id="3">
<a title="Hyperlink3">HyperLink3</a>
</li>
</ul>
</div>
<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.

JQuery hide/show not working as it should

I'm trying to make a drop down menu and have it open sub menus on click and close them on click, but I cannot even get it to hide my submenu to start off with on a click.
Here is my JQuery code:
$(document).ready(function(){
$("#timeli").click(function(){
$("#timeUlSub").hide();
});});
And this is my html code that I am trying to get to hide/show
<div class="timeline">
<ul>
<li id="timeli">1996
<ul id="timeUlSub">
<li>
<p class="timeline-date">1997</p>
<p class="timeline-description">This is in the submenu</p>
</li>
</ul>
</li>
<li>1999</li>
<li>2000</li>
<li>2004</li>
<li>2006</li>
<li>2007</li>
</ul>
</div>
Am I doing something wrong on the jquery end? Because from what I have looked on here this should be working, but it's not.

Using toggle() may be more effective:
$("#timeli").click(function(){
$("#timeUlSub").toggle();
});
Example Fiddle

$(document).ready(function(){
$("#timeli").on('click', function()
{
$("#timeUlSub").toggle();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="timeline">
<ul>
<li id="timeli">1996
<ul id="timeUlSub">
<li>
<p class="timeline-date">1997</p>
<p class="timeline-description">This is in the submenu</p>
</li>
</ul>
</li>
<li>1999</li>
<li>2000</li>
<li>2004</li>
<li>2006</li>
<li>2007</li>
</ul>
</div>

#timeUlSub is part of the #timeli li. Move it outside the li. In addition, jquery .slideToggle() is a better method than .hide().
Check if you have Jquery linked.

Try this out for conditional usage :
$(document).ready(function(){
$("#timeli").on('click', function(){
if($("#timeUlSub").is(':hidden')){
$("#timeUlSub").show();
} else {
$("#timeUlSub").hide();
}
});
});

<div class="timeline">
<ul>
<li id="timeli">1996
<ul id="timeUlSub">
<li>
<p class="timeline-date">1997</p>
<p class="timeline-description">This is in the submenu</p>
</li>
</ul>
</li>
<li>1999</li>
<li>2000</li>
<li>2004</li>
<li>2006</li>
<li>2007</li>
</ul>
</div>
#timeUlSub{
display:none;
}
$(document).ready(function(){
$("#timeli").click(function(){
$("#timeUlSub").toggle();
});});

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 pass this element to javascript onclick function and add a class to that clicked element

I had an html navigation code as below
function Data(string) {
//1. get some data from server according to month year etc.,
//2. unactive all the remaining li's and make the current clicked element active by adding "active" class to the element
$('.filter').removeClass('active');
$(this).addClass('active');
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="row" style="padding-left:21px;">
<ul class="nav nav-tabs" style="padding-left:40px;">
<li class="active filter">This Month</li>
<li class="filter">Year</li>
<li class="filter">60 Days</li>
<li class="filter">90 Days</li>
</ul>
</div>
When the user clicks on any of the tabs
all the remaining tabs should be unactive,
and the current element/tab should be active,
My code above is not working.
How to make the above code work?
I only want to use javascript onclick for this. Is there any way that the this(current) object is send when the user clicks on the tab?

Use this html to get the clicked element:
<div class="row" style="padding-left:21px;">
<ul class="nav nav-tabs" style="padding-left:40px;">
<li class="active filter">This Month</li>
<li class="filter">Year</li>
<li class="filter">60 Days</li>
<li class="filter">90 Days</li>
</ul>
</div>
Script:
function Data(string, el)
{
$('.filter').removeClass('active');
$(el).parent().addClass('active');
}

Try like
<script>
function Data(string)
{
$('.filter').removeClass('active');
$(this).parent('.filter').addClass('active') ;
}
</script>
For the class selector you need to use . before the classname.And you need to add the class for the parent. Bec you are clicking on anchor tag not the filter.

<div class="row" style="padding-left:21px;">
<ul class="nav nav-tabs" style="padding-left:40px;">
<li class="active filter">This Month</li>
<li class="filter">Year</li>
<li class="filter">60 Days</li>
<li class="filter">90 Days</li>
</ul>
</div>
<script>
function Data(element)
{
element.removeClass('active');
element.addClass('active') ;
}
</script>

You have two issues in your code.. First you need reference to capture the element on click. Try adding another parameter to your function to reference this. Also active class is for li element initially while you are tryin to add it to "a" element in the function.
try this..
<div class="row" style="padding-left:21px;">
<ul class="nav nav-tabs" style="padding-left:40px;">
<li class="active filter">This Month</li>
<li class="filter">Year</li>
<li class="filter">60 Days</li>
<li class="filter">90 Days</li>
</ul>
</div>
<script>
function Data(string,element)
{
//1. get some data from server according to month year etc.,
//2. unactive all the remaining li's and make the current clicked element active by adding "active" class to the element
$('.filter').removeClass('active');
$(element).parent().addClass('active') ;
}
</script>

You can use addEventListener to pass this to a JavaScript function.
HTML
<button id="button">Year</button>
JavaScript
(function () {
var btn = document.getElementById('button');
btn.addEventListener('click', function () {
Date('#year');
}, false);
})();
function Data(string)
{
$('.filter').removeClass('active');
$(this).parent().addClass('active') ;
}

Target parent next div

I´m trying to target a <div> which is the next <li> of the parent <div> of the function show_projectinfo(). I've tried .next(), .closest(), etc... with no luck, any ideas?
The function is that if I click on a.more_info then the li.slider img is hidden... I don´t know if it is out of scope completely... This is a div that is repeated so I can´t just use the IDs.
markup:
<li class="info">
<a id="previous-slider"> < </a>
<span>01/15</span>
<a id="next-slider" href="javascript:void(0)"> > </a>
<a class="more_info" href="javascript:void(0)" onclick="show_projectinfo()">Info</a>
</li>
<li class="slider">
<img src="img/horizontal.jpg" alt="horizontal" width="624" height="429">
</li>
this is the script:
function show_projectinfo(){
$(this).closest('.slider img').hide();
$('.info_content').fadeIn();
}

The basic problem is that you are calling the method from onclick instead of binding it with jquery.
In the way you use it, the this refers to the window and not the element that was clicked.
function show_projectinfo(e){
e.preventDefault();
$(this).parent().next().find('img').hide();
$('.info_content').fadeIn();
}
$(function(){
$('.more_info').click(show_projectinfo);
});
and remove the onclick attribute from the html
If you have (although you shouldn't) to use the onclick attribute then pass it the this as an argument
function show_projectinfo(element){
$( element ).parent().next().find('img').hide();
$('.info_content').fadeIn();
}
and
<a class="more_info" href="javascript:void(0)" onclick="show_projectinfo(this)">Info</a>

Try:
$(this).parent().next() // parent() should be the <li> then next() will get your next <li>

$('.more_info').click(function(e){
e.preventDefault();
$(this).parent().next().find('img').hide();
$('.info_content').fadeIn();
});

Instead of .closest use .parent and .next, then select the img with .find.
Check out this jsFiddle:
$("a.more_info").bind("click", function(e){
e.preventDefault();
$(this).parent("li").next("li.slider").find("img").hide();
$('.info_content').fadeIn();
return false;
});

$('li').click( function (){
var nextLi = $(this).closest('div').next().children('li:first-child').attr('id');
console.log(nextLi);
});
Considering below markup:
<div id='div1'>
<li id='1'>1</li>
<li id='2'>2</li>
<li id='3'>3</li>
</div>
<div id='div2'>
<li id='4'>4</li>
<li id='5'>5</li>
<li id='6'>6</li>
</div>
You can see my live jsFiddle for more details.
