JQUERY - toggle divs based on ID - javascript

I have a large number of DIVs on a page. Each being a container for an Unordered List. Above each DIV is a header text which consists of an element with an anchor.
e.g.
<h2><a id="header1" href="#" > Header 1 </a></h3>
<div id="container1">
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
</div>
<h2><a id="header2" href="#" > Header 2 </a></h3>
<div <div id="container2">>
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
</div>
I need to have all these DIVs hidden until the header (anchor) is clicked. If the user clicks header it should toggle show/hide DIV
How can I accomplish this in JQUERY in a way that I can have one onClick function for all the DIVS, possibly using an id to differentiate between divs?
<h2> Header 1 </h3>
function toggleDiv(id) {
}
but in JQUERY ?
SOLVED!!!!
<script>
$(function(){
$('.toggle-link').on('click', function() {
var linkId = $(this).attr('data-div-id');
$('#' + linkId).toggle();
});
});
</script>
<h2> Header 1 </h2>
<div id="div1">
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
</div>
<h2> Header 2 </h2>
<div id="div2">
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
</div>


You can use .toggle() in jQuery
toggle() method toggles between hide() and show() for the selected
elements.
function toggleDiv(id) {
$('#'+id).toggle();
}
where id is the parameter you pass

Make parent link unclickable in submenu toggle

I am trying to make a sub-menu toggle on mobile but it keeps on redirecting to the parent menu link and adding event.preventDefault(); making entire sub-menu links unclickable. Any idea how to make only first .has-childern a link unclickable?
Markup
<div class="menu-container">
<ul class="nav-menu">
<li class="menu item"> Home </li>
<li class="menu-item has-childern"> About
<ul class="submenu">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</li>
<li class="menu-item has-childern"> Services
<ul class="submenu">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</li>
<li class="menu item"> Contact </li>
</ul>
</div>
jQuery
jQuery(document).ready(function(){
jQuery('.menu-container .submenu').hide();
jQuery('.menu-container .has-childern a').click(function() {
event.preventDefault();
jQuery(this).parent().children('.submenu').toggle();
});
});
JsFiddle https://jsfiddle.net/p5fLsvcq/

You code affect all nested children instead just direct child
use '>' for select just a direct first level child in selector:
jQuery('.menu-container .has-childern > a').click(/*...*/)

How to add class to parent when child is visible?

I have a menu with a sub menu, when the sub menu is visible I want to add a class to parent list element.
<ul class="upper-menu">
<li>Item 1</li>
<li>Item 2</li>
<li class="parent-li">Item 3
<ul class="lower-menu">
<li>Sub Item 1</li>
<li>Sub Item 2</li>
</ul>
</li>
<li>Item 4</li>
</ul>
Basically, when the "lower-menu" is visible, I want to add another class to the list element "parent-li". Also when the lower-menu is not visible, I want to the remove the class from "parent-li". Is this possible in JQuery?
Thanks

You can do by following jquery script
if($('.lower-menu').is(':visible')){
$(this).parent().addClass("YourClass");
}

You can select the desired element by :visible pseudo class and then assign your class to its parent:
$(".lower-menu:visible").closest('.parent-li').addClass("test");
.test {
background-color: yellow;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="upper-menu">
<li>Item 1</li>
<li>Item 2</li>
<li class="parent-li">Item 3
<ul class="lower-menu">
<li>Sub Item 1</li>
<li>Sub Item 2</li>
</ul>
</li>
<li>Item 4</li>
</ul>

How to wrap all `ul` elements in `div` with JQuery automatically?

How to wrap all ul elements in div with JQuery automatically?
<div id="my_uls">
<ul>
<li>Item one</li>
<li>Item two
<ul>
<li>Item one of two</li>
</ul>
</li>
</ul>
</div>
But what I want:
<div id="my_uls">
<div>
<ul>
<li>Item one</li>
<li>Item two
<div>
<ul>
<li>Item one of two</li>
</ul>
</div>
</li>
</ul>
</div>
</div>

You need to use .wrap():
$(function() {
$("ul").wrap("<div />");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="my_uls">
<ul>
<li>Item one</li>
<li>Item two
<ul>
<li>Item one of two</li>
</ul>
</li>
</ul>
</div>

Just use wrap function for this
<scrpt>
$(document).ready(function(){
var myuls = $("#my_uls").find("ul");
for(var i=0;i<myuls.length;i++){
$(myuls[i]).wrap("<div></div>");
}
});
</script>

$('#my_uls ul'), This will refer all your ul inside the div.
if you need the 1st ul only
$('#my_uls ul:not(#my_uls ul ul)').

Getting the element at the same level of parent

I want to add a class to the preceding h3 element whenever any of the li under it being clicked, here is my html:
<div class="list">
<div class="marketing">
<h3> List I</h3>
<div>
<ul>
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
</ul>
</div>
</div>
<div class="operations">
<h3> List II</h3>
<div>
<ul>
<li>item a</li>
<li>item b</li>
<li>item c</li>
</ul>
</div>
</div>
</div>
I tried to use the following script but in vain.
$('.list li').click(function () {
$(this)parent().prev('h3').addClass('active');
);
or either
$('.list li').click(function () {
$(this).parent().parent().children('h3')addClass('active');
);
Any idea?

use:
$(this).closest('div').prev('h3').addClass('active');
or
$(this).closest('div').siblings('h3').addClass('active');

Use this
$('.list li').click(function () {
$(this).parent().parent().prev().addClass('active');
});

jQuery find id then do action

I am trying to make this little code work. I have a normal drop-down menu and I want to turn it into a drop-down list (select).
The normal menu has a "tm_active" id attached to show which page you are on. I want to use jquery and find this id, then when page loads to select the right item according to what page you are on (not the first item in the list).
What am I doing wrong guys?
Thank you.
$('table.topMenu tr').each(function(){
var list=$(this),
select=$(document.createElement('select')).insertBefore($(this).hide()).change(function(){
window.location.href=$(this).val();
});
$('>td a', this).slice(2).each(function(){
var option=$(document.createElement('option'))
.appendTo(select)
.val(this.href)
.html($(this).html());
if($(this).attr('id') === 'tm_active'){
option.attr('selected','selected');
}
});
list.remove();
});
HTML
<table>
<tr>
<td class="top">
Section 1
<div class="sub">
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
</div>
</td>
<td class="top" id="tm_active">
Section 2
<div class="sub">
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
</div>
</td>
<td class="top">
Section 3
<div class="sub">
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
</div>
</td>
</tr>
</table>

You are checking the id of the anchor tag you should check the parent td:
$(this).parent().attr('id') === 'tm_active'
