jquery fadein on buttonclick

I'm making a Bootstrap site and I want jQuery to fade in my text on a button click. This is my code:
$(document).ready(function() {
$('div.hidden').fadeIn(1000).removeClass('hidden');
});
$(#homebutton).onclick(function() {
$('#homebutton.hidden').fadein(1000).removeClass('hidden');
});

I'm new to jQuery and I don't know what I did wrong. Thanks in advance,

With revised HTML and jquery targets:
$(document).ready(function() {
$('.section0 .hidden').fadeIn(1000).removeClass('hidden');
});
$('#homebutton').on('click', function() {
$('.section1 .hidden').fadeIn(1000).removeClass('hidden');
});

I think you wanna fade in section1 text when u click the button, update like this:
$('#homebutton').on('click', function() {
$('.container-fluid').fadeIn(1000).removeClass('hidden');
});

Bootstrap 3 keep menu open and show div

I've built a Nav bar with a profile dropdown (right hand side of menu):
http://www.bootply.com/Rqj51l2VFO
<nav class="navbar navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div class="collapse navbar-collapse" id="myNavbar">

</a>
<ul class="dropdown-menu">

</div>
<div class="col-lg-8">
<p class="text-left"><strong>Email Address</strong></p>
<p class="text-left small">{$person['main_location[email]']}</p>
</div>

<div class="navbar-login navbar-login-session">
<div class="row">
<div class="col-lg-3"></div>
<div class="col-lg-6">

</div>
</li>
</ul>

</ul>
</div>
</div>
</nav>
When I click the change photo link, I want a Div to open and the menu to stay open so the user can interact with an input that shows I.e the user would enter a URL to the photo they want in the profile.
This works fine but the menu disappears. So I added the following JS so the menu stays:
JS:
$('#menu .dropdown-menu').on({
"click": function(e) {
e.stopPropagation();
}
});
The issue I have is that now the menu stays open - the bootstrap collapse class isn't working to show/hide.
Could anybody explain what I'm doing wrong here please?

Here is one way to keep the dropdown open after click and keep collapse class working to show/hide. ...
add ID to your Change photo button:
<p>Change Photo</p>
use this following function:
$('#change-photo').on('click', function () {
$('#change_pic').toggle();
return false;
});

Bootstrap navbar toggle use to add class

I use Bootstrap V3 in Wordpress.
What I want to achieve is that when someone clicks the button in the collapsed navbar menu, the div with the class .slider gets a extra class.
This is the HTML from the navbar:
<nav class="navbar navbar-default navbar-static-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div class="collapse navbar-collapse" id="navbar">
<?php
wp_nav_menu( array(
'theme_location' => 'navbar-right',
'depth' => 2,
'menu_class' => 'nav navbar-nav navbar-right',
'fallback_cb' => 'wp_bootstrap_navwalker::fallback',
'walker' => new wp_bootstrap_navwalker())
);
?>
</div><!-- /.navbar-collapse -->
</div><!-- /.container -->
</nav>
And this is the HTML from the div where I want to add a extra class:
<div class="slider">
<div class="container">
<div class="row">
other elements
</div> <!-- close row -->
</div> <!-- close container -->
</div> <!-- close slider -->
I've tried this with CSS:
.navbar-default .navbar-collapse .in ~ .slider{
margin-top: -246px;
padding-top: 176px;
}
And this with jQuery:
$(function() {
$("#navbar").click(function() {
$(".slider").addClass("sliderMove");
});
});
The extra class that should be added on slider is:
.sliderMove{
margin-top: -246px;
padding-top: 176px;
}
The purpose of this is that the slider that is after/under the navbar stay's under the navbar when it collapsed.

You just need to hook into the Bootstrap collapse event of your collapsible navbar. There is no need to assign an extra click handler to the collapse nav button.
Collapse Events
Bootstrap's collapse class exposes a few events for hooking into collapse functionality.
Here is an example.
$('#bs-example-navbar-collapse-1').on('show.bs.collapse', function () {
$(".slider").addClass("your-class");
})
$('#bs-example-navbar-collapse-1').on('hide.bs.collapse', function () {
$(".slider").removeClass("your-class");
})
.slider {
width: 100%;
min-height: 100px;
background-color: tomato;
}
.your-class {
background-color: lawngreen;
}

<nav class="navbar navbar-default">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Brand</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li>Link <span class="sr-only">(current)</span></li>
</ul>
</div>
</div>
</nav>
<div class="slider"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

The button you are are willing to click is having a class navbar-toggle and the div having navbar has an id navbar . So to achieve the click event on button you have to use the button id not the div id. So your jQuery code will go like:
$('.navbar-toggle').click(function(){
if($('#navbar').hasClass('in')){
$(".slider").addClass("sliderMove");
}else{
$(".slider").removeClass("sliderMove");
}
});
As you would like to remove the class when you collapse the menu again using same button.

you were doing everything fine, but you need to use toggleClass() and select other CSS selector that is not #navbar
it also possible to add a delay? Because the class is already activated before the navbar is fully collapsed.
Yes it is possible, by adding setTimeout()
$(".collapsed").click(function() {
// toggle the class after half second
setTimeout(function() {
$(".slider").toggleClass("sliderMove");
}, 500);
});
/* just to show in small devices */
#media (max-width: 992px) {
.sliderMove {
background: red;
height: 100vh;
width: 100%
}
}

Try something like this:

$('body').ready(function() {
$('.navbar-toggle').on('click', function() {
$(".slider").toggleClass("sliderMove");
});
});

Try this
<nav class="navbar navbar-default navbar-static-top">

how to use JS function to change class of list dynamically

I want to change the class of list item dynamically according to user's click on it. I have a menu and I want to assign .active class to only that menu which is clicked by user and initially Home Menu must be active
Here is my code
function activeclass(id)
{
document.getElementById(id).className += "active";
}
<section id="menu-area">
<nav class="navbar navbar-default" role="navigation">
<div class="container">
<div class="navbar-header">
<!-- FOR MOBILE VIEW COLLAPSED BUTTON -->
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<!-- LOGO -->
<!-- TEXT BASED LOGO <a class="navbar-brand" href="index.html">Inventive</a> -->
<!-- IMG BASED LOGO -->
<a class="navbar-brand" href="index.html"><img class="img-responsive" src="assets/images/logo.png" alt="logo" width="200"></a>
</div>
<div id="navbar" class="navbar-collapse collapse">
<ul id="top-menu" class="nav navbar-nav navbar-right main-nav">
#yield('logo')
<li id="home">Home</li>
<li id="aboutus">About Us</li>
<li id="products">Products</li>
<li id="gallery"><a href="{{ URL::route('gallery') }}" onclick="activeclass(id)" >Gallery</a></li>
<li id="contactus">Contact</li>
</ul>
</div><!--/.nav-collapse -->
</div>
</nav>
</section>
in CSS file active class with li will be used to highlight the selected page menu

Although there are better ways to achieve the thing you want (like the #Jitendra Tiwari's answer or my example below), I want to point you to the problem in your code.
The problem is that you pass to the function activeclass an unknown parameter: id.
When you debug your code you can see that the id param is empty:
You need to pass a string parameter with the relevant id:
function activeclass(id) {
document.getElementById(id).className += "active";
}
.active {
background:red;
}
<nav class="navbar navbar-default" role="navigation">
<div class="container">
<div class="navbar-header">
<!-- FOR MOBILE VIEW COLLAPSED BUTTON -->
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<!-- LOGO -->
<!-- TEXT BASED LOGO
<a class="navbar-brand" href="index.html">Inventive</a> -->
<!-- IMG BASED LOGO -->
<a class="navbar-brand" href="index.html"><img class="img-responsive" src="assets/images/logo.png" alt="logo" width="200"></a>
</div>
<div id="navbar" class="navbar-collapse collapse">
<ul id="top-menu" class="nav navbar-nav navbar-right main-nav">
#yield('logo')
<li id="home">Home</li>
<li id="aboutus">About Us</li>
<li id="products">Products</li>
<li id="gallery"><a href="#" onclick="activeclass('gallery')" >Gallery</a></li>
<li id="contactus">Contact</li>
</ul>
</div><!--/.nav-collapse -->
</div>
</nav>

Also, remove the public keyword from your code. It's not in javascript
A working example without jQuery:
[].forEach.call(document.querySelectorAll('#top-menu a'), function(elm) {
elm.addEventListener('click', function() {
var active = document.querySelector('.active');
if (active) {
active.classList.remove('active');
}
elm.parentNode.classList.add('active');
});
});
.active {
background:red;
}
<nav class="navbar navbar-default" role="navigation">
<div class="container">
<div class="navbar-header">
<!-- FOR MOBILE VIEW COLLAPSED BUTTON -->
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<!-- LOGO -->
<!-- TEXT BASED LOGO
<a class="navbar-brand" href="index.html">Inventive</a> -->
<!-- IMG BASED LOGO -->
<a class="navbar-brand" href="index.html"><img class="img-responsive" src="assets/images/logo.png" alt="logo" width="200"></a>
</div>
<div id="navbar" class="navbar-collapse collapse">
<ul id="top-menu" class="nav navbar-nav navbar-right main-nav">
#yield('logo')
<li id="home">Home</li>
<li id="aboutus">About Us</li>
<li id="products">Products</li>
<li id="gallery">Gallery</li>
<li id="contactus">Contact</li>
</ul>
</div><!--/.nav-collapse -->
</div>
</nav>

You need to remove active class from other li and add on currently clicked item.
Try this
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('li').click(function(){
// Step 1 - remove active class from all `li`
$('li').removeClass('active');
// Step 2 - add active class on currently clicked li
$(this).addClass('active');
});
});
</script>
Don't forgot to include jquery library.

Using Javascript, you can use the below code:
var ul = document.getElementById("top-menu");
var li = ul.getElementsByTagName("li");
//Set the Home menu as active for first time
li[0].classList.add("active");
//add click event listener for each menu item, and add class active on current clicked menu item.
for(var i=0; i<li.length; i++){
li[i].addEventListener("click", function(){
removeActiveClass();
this.classList.add("active");
});
}
//Remove the active class from the menu items
function removeActiveClass() {
for(var i=0; i<li.length; i++){
li[i].classList.remove("active");
}
}
I have not used any jQuery. Hope this helps you. You do not need to add click event on HTML. Just the below HTML is enough:
<ul id="top-menu">
<li>Home</li>
<li>About</li>
<li>Products</li>
<li>Gallery</li>
<li>Contact</li>
</ul>

Try this method.
<ul id="top-menu" class="nav navbar-nav navbar-right main-nav">
#yield('logo')
<li id="home">Home</li>
<li id="aboutus">About Us</li>
<li id="products">Products</li>
<li id="gallery"><a href="{{ URL::route('gallery') }}" class="{{ \Request::route()->getName() == 'gallery' ? 'active' : '' }}" >Gallery</a></li>
<li id="contactus">Contact</li>
</ul>

Bootstrap 3 When clicking dropdown menu navbar-collapse is closing

I have a basic Bootstrap 3 responsive nav like so:
<body data-spy="scroll" data-offset="0" data-target="#navbar-main">
<div id="navbar-main">
<!-- Fixed navbar -->
<div class="navbar navbar-custom navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse"><span
class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span></button>
<a class="navbar-brand" href="#"><strong>brand</strong></a></div>
<div class="collapse navbar-collapse">
<ul class="nav navbar-nav navbar-right">
<li>Homepage</li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">page-1</a>
<ul class="dropdown-menu">
<li>page-1-1</li>
<li>page-1-2</li>
</ul>
</ul>
</div>
<!--/.nav-collapse -->
</div>
</div>
</div>
</body>
When I click the dropdown menu button in collapsed mode, navbar is closing and I cannot see the dropdown menu.
When I open nav:
and clicked Page-1:
It should open a dropdown menu below Page 1 but when I click Page-1 it closes nav. How can I solve this problem?
