how to add javascript function to a class of active? - javascript

how to add javascript function to a class of active ??
I do not understand completely about javascript.
if i click menu its like remove and add new class nav active.
<div id="sidebar">
<ul id="mainNav">
<li id="navDashboard" class="nav active">
<span class="icon-home"></span>
Beranda
</li>
<li id="navPages" class="nav">
<span class="icon-document-alt-stroke"></span>
Data Profil
<ul class="subNav">
<li>Peta Lokasi</li>
<li>Site Plan</li>
</ul>
</li>

You can use something like this:
$(selector).click(function(){
$(this).removeClass(your class)
.addClass('active');
});
You have to define the selector you want to do something.

Loop through DOM elements with JQuery to assign a click handler

I need to loop through the DOM with JQuery, and add a click handler to multiple parent elements that contain a child that will also be given a slideToggle(). I have the logic working fine when I add the click handlers manually, but now I need to be able to dynamically do this to multiple parent elements.
Here is my HTML:
<div class="map-poi-nav">
<ul class="map-poi-nav-dropdown">
//Parent #1
<li class="sub-menu-link" id="sub-menu-link-1">
<a href="#">
<img src="https://svgshare.com/i/ADc.svg"> Activities
</a>
</li>
<li class="sub-menu">
<ul class="sub-menu-list" id="sub-menu-list-1">
<li><a><span>•</span>Golden State Park</a></li>
<li><a><span>•</span>Sunrise Oaks City Park</a></li>
</ul>
</li>
</ul>
<ul class="map-poi-nav-dropdown">
//Parent #2
<li class="sub-menu-link" id="sub-menu-link-2">
<a href="#">
<img src="https://svgshare.com/i/ADc.svg"> Dining
</a>
</li>
<li class="sub-menu">
<ul class="sub-menu-list" id="sub-menu-list-2">
<li><a><span>•</span>The Loft Grill</a></li>
<li><a><span>•</span>Fish Grill & Bar</a></li>
</ul>
</li>
</ul>
</div>
Basically, you click on .sub-menu-link to slideToggle() .sub-menu-list.
Here is the JS that I have working so far. It targets the id's manually currently, which feels gross:
$('#sub-menu-link-1').click(function() {
$('#sub-menu-list-1').slideToggle(100);
$(this).toggleClass('active-menu-link');
});
$('#sub-menu-link-2').click(function() {
$('#sub-menu-list-2').slideToggle(100);
$(this).toggleClass('active-menu-link');
});
My apologies if this is something very apparent to do in JQuery. I am not at all familiar with it, and it just so happens to be a requirement of this project.
you could simply use below code.
select all list items with class name and add listener. click will be attached to all elements
$('.sub-menu-link').click(function() {
$(this).slideToggle(100);
$(this).toggleClass('active-menu-link');
});
You already have classes, so just use them instead of the ids: use this to refer to the clicked element, .next() to get the next sibling (the li.sub-menu), and .find('.sub-menu-list') to get to the ul you want to toggle:
$('.sub-menu-link').click(function() {
const $subMenuList = $(this).next().find('.sub-menu-list');
console.log($subMenuList.text().trim());
$subMenuList.slideToggle(100);
$(this).toggleClass('active-menu-link');
});

<li><a><span>•</span>Fish Grill & Bar</a></li>
</ul>
</li>
</ul>

You can use jQuery's .next() like so:
$(".sub-menu-link").click(function() {
$(this).next(".sub-menu-link").slideToggle(100);
$(this).toggleClass("active-menu-link");
})
Or you can chain them and use ES6 arrow syntax to make it more concise:
$(".sub-menu-link").click(() => $(this).toggleClass("active-menu-link").next(".sub-menu-link").slideToggle(100));
You should try this if your list and link ids have similiar pattern as in the code you have shown
$('#sub-menu-link').click(function() {
var id = $(this).attr("id").replace("sub-menu-link", "")
$('#sub-menu-list-'+ id).slideToggle(100);
$(this).toggleClass('active-menu-link');
});

javascript horizontal menu click to open

Trying to make javascript horizontal menu, but can't get second button to open its own items, (when i click the second button it opens the items that are for the first button) here is current code:
JavaScript:
$(document).ready(function() {
$(".menu-button,.menu-button1").click(function() {
$(".menu-bar").toggleClass("open");
});
})
HTML:
<ul class="menu">
<li title="home">menu</li>
<li title="pencil">pencil</li>
<li title="about">about</li>
</ul>
<ul class="menu-bar">
<li>Menu0</li>
<li>Home2000</li>
<li>About</li>
<li>Parent</li>
<li>About</li>
</ul>
<ul class="menu-bar">
<li>Menu1</li>
<li>About</li>
</ul>
Before I start my answer, let me explain jQuery a bit.
$(".menu-button,.menu-button1").click(function() {
$(".menu-bar").toggleClass("open");
});
This broken down:
$(".menu-button,.menu-button1").click(function() { -> When any item with class menu-button OR class menu-button1 is clicked
$(".menu-bar").toggleClass("open"); ->Toggle the "open" class for all elements in your page with class menu-bar.
Since you call all the menus instead of the specific one you want, it opens both of them.
So, be more specific by - for starters - using IDs, or unique/identifying classes:
JS:
$(document).ready(function() {
$(".menu-button.home").click(function() {
$(".menu-bar.home").toggleClass("open");
});
$(".menu-button.pencil").click(function() {
$(".menu-bar.pencil").toggleClass("open");
});
})
HTML:
<ul class="menu">
<li title="home">menu</li>
<li title="pencil">pencil</li>
<li title="about">about</li>
</ul>
<ul class="menu-bar home">
<li>Menu0</li>
<li>Home2000</li>
<li>About</li>
<li>Parent</li>
<li>About</li>
</ul>
<ul class="menu-bar pencil">
<li>Menu1</li>
<li>About</li>
</ul>
I agree with M.Doye's comment about using .each (but sorry, I can't answer directly).
I want to add that, it will be much easier with that kind of HTML structure I think:
<ul class="menu">
<li title="home">
Show Menu 1
<ul class="menu-bar">
<li>Menu1
</li>
</ul>
</li>
<li title="pencil">
Show Menu 2
<ul class="menu-bar">
<li>Menu2
</li>
</ul>
</li>
</ul>
The, click on the link and use .next() or .siblings or closest... to show the right ul.
But of course you'll have to rewrite you CSS :)
Here is updated code
$(document).ready(function () {
$(".menu-button,.menu-button1").click(function () {
$(this).siblings(".menu-bar").toggleClass("open");
})
})
<ul class="menu">
<li title="home">menu
<ul class="menu-bar">
<li>Menu1</li>
<li>About</li>
</ul>
</li>
<li title="pencil">pencil
<ul class="menu-bar">
<li>Menu0</li>
<li>Home2000</li>
<li>About</li>
<li>Parent</li>
<li>About</li>
</ul>
</li>
</ul>

How to hide Show section with menu click?

I create a menu :
<ul class="navigation-bar navigation-bar-left">
<li class="active">About</li>
<li>schedule</li>
<li>speakers</li>
<li>Map</li>
<li class="featured"><i class="fa fa-play-circle fa-1x"></i>Register</li>
</ul>
And I want to show/hide the corresponding sections :
<section id="about" class="section dark">
Thanks !
Use jquery toggle() method to do this in simple way.
Refer http://www.w3schools.com/jquery/tryit.asp?filename=tryjquery_toggle
If you have a structure like
<ul class="navigation-bar navigation-bar-left">
<li class="active">About</li>
<li>schedule</li>
<li>speakers</li>
<li>Map</li>
<li class="featured"><i class="fa fa-play-circle fa-1x"></i>Register</li>
</ul>
<section id="sec-about" class="section dark"><h2>About</h2></section>
you could toggle the section like
document.getElementById('nav_about').addEventListener('click', function(){
var secAbout = document.getElementById('sec-about');
if( getComputedStyle(secAbout,null).display=='none') secAbout.style.display='block';
else secAbout.style.display='none';
}, false);

</ul>

</ul>
</nav>
I can see at least two possible issues there.
1) sub-nav-list is not a children of click element. If they are on the same level something like that might work:
$('.click').click(function() {
$(this).parent().find('.sub-nav-list').toggleClass('active');
});
2) You have these elements generated dynamically - so you need use on with selector of any parent element that exists before you dynamically generate your sub-menus (let say nav-list):
$(".click").on("click", ".nav-list", function() {
$(this).parent().find('.sub-nav-list').toggleClass('active');
});

jquery find() method not working

Recently I am having a problem with my jquery code. I was trying to get the elements from the html using the jquery find method but its not working. I have tried changing the elements name but still i cant find where is my mistake.
Here is the following html code:
<div class="navbar-collapse collapse">
<nav>
<ul class="nav navbar-nav navbar-right">
<li class = "dropdown"><span>About Us</span><b class = "caret"></b>
<ul class = "dropdown-menu">
<li data-slide = '1'>Philosophy</li>
<li>Founding Members</li>
<li>Committee</li>
<li>Code of Ethics</li>
</ul>
</li>
<li data-slide='2'>Digital Ecosystem</li>
<li data-slide='3'>Fellow & Members</li>
<li data-slide='4'>SIGs</li>
<li data-slide='5'>Local Chapters</li>
<li data-slide="7">Events</li>
<li data-slide="8">Our Service</li>
<li>
<a href="#" onClick="window.open('logout.php','_self','width=400,height=200,toolbar=yes, location=yes,directories=yes,status=yes,menubar=yes,scrollbars=yes,copyhistory=yes, resizable=yes')">
<?php
if (isset($_SESSION['CurrentUser'])) {
echo "Log Out";
}
?>
</a>
</li>
<li>
<a href="#" onClick="window.open('login.php','_self','width=400,height=200,toolbar=yes, location=yes,directories=yes,status=yes,menubar=yes,scrollbars=yes,copyhistory=yes, resizable=yes')">
<?php
if (!isset($_SESSION['CurrentUser'])) {
echo "Login/Register";
}
?>
</a>
</li>
</ul>
</nav>
</div>
I have included my jquery code too :
var links = $('.nav, .navbar-nav, .navbar-right').find('li');
Actually what the code does is once it find the 'li' html elements it slides the page each time a 'li' element is being clicked. Now if I click on the 'li' elements my page doesnt scrolls to the selected page. it would be great if someone is there to solve my problem.
Try this (if you really want the "links" tags):
var links = $('.nav.navbar-nav.navbar-right').find('a');
