Create click off event on animated navigation dropdown - javascript

I have 2 problems:
I'm trying to create an click-off event, where a click off of the "nav" menu is detected, which triggers the deselection of the open list element and retracts its respective dropdown content.
My current code doesn't allow another list element/navigation item without dropdown content to be added, as doing so hinders the entirety of the code from working. I'd like to add another "nav" list element that doesn't have dropdown contents, without hindering the functionality of the other list elements and their respective dropdown content.
Here is my code (also available on JSFiddle):
$(function() {
function animate() {
$('#nav .nav-ul li').off('click', animate)
var $detected = $(this).closest('.nav-ul');
$detected.find('li.detected').removeClass('detected');
$(this).addClass('detected');
//figure out which rel to show
var ulToShow = $(this).attr('rel');
//hide current rel
if ($('.substitute .sub-child.active').length > 0) {
$('.substitute .sub-child.active').hide(700, function() {
$(this).removeClass('active');
$('#' + ulToShow).fadeIn(528, function() {
$(this).addClass('active');
$('#nav .nav-ul li').on('click', animate)
});
});
} else {
$('#' + ulToShow).fadeIn(528, function() {
$(this).addClass('active');
$('#nav .nav-ul li').on('click', animate)
});
}
}
$('#nav .nav-ul li').on('click', animate);
});
* {
margin: 0;
padding: 0;
}

#nav .nav-ul {
list-style: none;

I'm trying to create an click-off event, where a click off of the "nav" menu is detected, which triggers the deselection of the open list element and retracts its respective dropdown content.
For this you could create a click event handler on the body that closes the menu if it's open. Something like this:
// close menu when clicking anywhere on the document
$(document).on("click", function() {
$("#nav li.detected").removeClass("detected");
$("#nav div.active").hide(700, function() { $(this).removeClass("active"); });
});
Then to avoid it from closing when you click on the menu, you can use .stopPropagation() in the animate function to stop the bubbling of the events up the DOM tree when clicking on it.
My current code doesn't allow another list element/navigation item without dropdown content to be added, as doing so hinders the entirety of the code from working. I'd like to add another "nav" list element that doesn't have dropdown contents, without hindering the functionality of the other list elements and their respective dropdown content.
This happens because you are associating and disassociating events every time that you click on the menu (something that is not really necessary), so when one of the navigation items doesn't have a dropdown associated to it, the event handler is removed (with the off() in the animate function) but it is not associated again, which causes this behavior that you don't want.
The solution is simple: there's no apparent need to be detaching and re-attaching the click event handlers every time that the animate function is called. Remove the call to off and on within the animate function and that would be it.
Here you can see both changes applied to your code:
$(function() {
function animate(e) {
e.stopPropagation();
var $detected = $(this).closest('.nav-ul');
if (!$detected.hasClass("active-animation")) {
$detected.addClass("active-animation");
$detected.find('li.detected').removeClass('detected');
$(this).addClass('detected');
//figure out which rel to show
var ulToShow = $(this).attr('rel');
//hide current rel
if ($('.substitute .sub-child.active').length > 0) {
$('.substitute .sub-child.active').hide(700, function() {
$(this).removeClass('active');
$('#' + ulToShow).fadeIn(528, function() {
$(this).addClass('active');
$detected.removeClass("active-animation");
});
});
} else {
$('#' + ulToShow).fadeIn(528, function() {
$(this).addClass('active');
$detected.removeClass("active-animation");
});
}
}
}
$('#nav .nav-ul li').on('click', animate);
// close menu when clicking anywhere on the page
$(document).on("click", function() {
$("#nav li.detected").removeClass("detected");
$("#nav div.active").hide(700, function() {
$(this).removeClass("active");
});
});

Change the active navbar color in css

I am using a simple top css navbar(just a css and html, without bootstrap/other framework) and i would like to change the active page. So when i go to the home page, the button color in navbar changes into red/whatever, likewise when i go to the other page...
here the code:
body {
margin: 0;
}
.logo {
margin: 0;
padding: 0;
overflow: hidden;
background-color: #f2f2f2;
float: left;
width: 25%;
}
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
li {
float: left;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 40px;
text-decoration: none;
font-size: 18px;
}
li a:hover {
background-color: #111;
}
<ul>
<li>Home</li>
<li>News</li>
<li>Contact</li>
<li>About</li>
<li>Division</li>
<li>Career</li>
<li>MChoice's</li>
</ul>
do you have an idea? it's ok to add javascript
Thanks a lot!

What I did here is when $(document).ready(function() {..} get the path using var url = window.location.pathname; so you know which link the user coming from therefore you know which menu item they clicked.
Then $('ul li a').each(function() {...} will check each menu item, try to match the url path with the menu's href attributes, if a match found, make that menu item active (with css active class added), if not match remove the active class if any. That should do the trick.
(note: assume your app is not single page app)
for Single page app it is much easier, deactive all menu item then active the one you clicked.
$(document).ready(function() {
//var url = window.location.pathname;
var url = 'http://stacksnippets.net/js#division';
console.log('url-->', url);
$('ul li a').each(function() {
var href = $(this).attr('href');
if (!!url.match(href)) {
$(this).addClass('active');
} else {
$(this).removeClass('active');
}
});
});
body {
margin: 0;
}
.logo {
margin: 0;
padding: 0;
overflow: hidden;
background-color: #f2f2f2;
float: left;
width: 25%;
}
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
li {
float: left;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 40px;
text-decoration: none;
font-size: 18px;
}
li a:hover {
background-color: #111;
}
.active {
background-color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>Home</li>
<li>News</li>
<li>Contact</li>
<li>About</li>
<li>Division</li>
<li>Career</li>
<li>MChoice's</li>
</ul>

The simplest solution would be to add an active class to the link of the page you're on:
<ul>
<li>Home</li>
<li>News</li>
<li>Contact</li>
<li>About</li>
<li>Division</li>
<li>Career</li>
<li>MChoice's</li>
</ul>
Then style those that class accordingly:
li a.active {
background: #F00;
}
If you're using a CMS (Wordpress, etc), adding some sort of active class on the active link is usually done for you. If you're doing your own static HTML, you would have to do it manually.

try below code for active menu
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('li a').on('click', function(){
$('li a').removeClass('active');
$(this).addClass('active');
});
});
</script>
<style type="text/css">
body {
margin: 0;
}
.logo {
margin: 0;
padding: 0;
overflow: hidden;
background-color: #f2f2f2;
float: left;
width: 25%;
}
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
li {
float: left;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 40px;
text-decoration: none;
font-size: 18px;
}
li a:hover, li a.active {
background-color: #111;
}
</style>
<ul>
<li>Home</li>
<li>News</li>
<li>Contact</li>
<li>About</li>
<li>Division</li>
<li>Career</li>
<li>MChoice's</li>
</ul>

To change the color of active link in your navigation you need to do the following things:
On click of navigation link add css class:
$('ul li a').click(function(){
$('li a').removeClass("active");
$(this).addClass("active");
});
Add CSS for active class
ul li a.active {
background-color: #f4f4f4;
}

One possible way is to use the active selector in CSS. This selector highlights the active element you are using when its clicked.
a:active {
background-color: yellow;
}
a:focus {
background-color: yellow;
}
You can use some JQuery to turn it on and off too. Try looking at this post here, I think you may have get your answer.

here is JSFiddle result
http://jsfiddle.net/Ag47D/775/

Here's a JSFiddle: https://jsfiddle.net/timhjellum/nw3n7eka/103/
This is a jQuery option which looks at the page URL (window.location) and specifically for a string which you define in the .indexOf(" add a unique string here ") and asks if that string is greater than -1, then locate the li element with the class you assigned to it, and add another class called active.
In the example I'm using "display" because that the URL for that iFrame that JSFiddle uses so hopefully that's not confusing.
Here's the navigation:
$(document).ready(function () {
if(window.location.href.indexOf("home") > -1) {
$(".home").addClass("active");
}
if(window.location.href.indexOf("display") > -1) {
$(".news").addClass("active");
}
//make one for each nav element
});
The HTML needs to be modified like:
<ul>
<li class="home">Home</li>
<li class="news">News</li>
<li class="contact">Contact</li>
<li class="about">About</li>
</ul>
And then a simple css addition:
li.active {
background-color: white;
}
li.active a {
color: black;
}
If you can't use jQuery, let me know but this is the easiest solution for you to implement and allow you to easily modify

You could try having separate classes in your CSS file, like "ul-home," "ul-news," etc. and define different background colors for each, then simply set the class for your <ul> tag on each page to match the class you want. So:
.ul-home {
background-color: red;
}
.ul-news {
backrgound-color: yellow;
}
And then on your home page:
<ul class="ul-home>
<li>Home</li>
<li>News</li>
</ul>
On your news page:
<ul class="ul-news">
<li>Home</li>
<li>News</li>
</ul>
Etc. with all the other pages you have.

How to insert text anchor inside attributes onclick?

I have a jquery tab and it's working fine.
Fiddle here
$(document).ready(function() {
$('.nnntabs ul a').on('click', function(e) {
var current = $(this).attr('href');
$('.tab-content > div' + current).fadeIn('slow').show().siblings().hide();
$(this).parent('li').addClass('active').siblings().removeClass('active');
e.preventDefault();
});
});
I just wanted to add more feature. The text anchor should be dynamically inserted inside the href and id attributes to activate the tab, or maybe replaced if there is a default value... The source of the value of href and id will be the text anchor of the menu. My fiddle sample is working fine because I inserted the values manually. Please help me turn this into reality... Thank you.

I think what you are looking for is
$(document).ready(function() {
var $content = $('.nnntabs > .tab-content > div');
$('.nnntabs > ul a').each(function(i) {
$(this).data('tab', 'tab-' + i);
$content.eq(i).attr('id', 'tab-' + i)
})
$('.nnntabs ul a').on('click', function(e) {
var current = $(this).data('tab');
$('#' + current).fadeIn('slow').show().siblings().hide();
$(this).parent('li').addClass('active').siblings().removeClass('active');
e.preventDefault();
});
});
.nnntabs {
width: 100%;
}
.nnntabs ul {
width: 100%;
margin: 0;
padding: 0;
}
.nnntabs ul li {
display: inline-block;
list-style: none;

stopping dropdown navigation bar from pushing elements aside

I have a dropdown navigation bar, and when elements like buttons or images are too high up on the page, the navigation bar pushes the elements to the right side when drop-down options appear. How do I stop this?
Navbar:
<nav id="nav1">
<ul>
<li>Home</li>
<li onmouseover = "DropDown1()" onmouseout="DropUp1()">Images<ul class="DropUp" id="Droplist1" >
<li class="DropDown"><a id="Droplist1" href="#">Test1</a></li>
<li class="DropDown">Test2</li>
<li class="DropDown">Test3</li></ul>
</li>
<li onmouseover = "DropDown2()" onmouseout="DropUp2()">Adverts<ul id="Droplist2" class="DropUp">
<li class="DropDown">Test1</li>
<li class="DropDown">Test2</li></ul>
</li>
<li>Data Validation</li>
<li>Security</li>
</ul>
</nav>
CSS:
nav#nav1 li a {
display: block;
padding: 3px 8px;
background-color: #5e8ce9;
color: #fff;
text-decoration: none;
}
nav#nav1 li {
list-style: none;
float: left;}
.DrowDown {
display: block;
position: absolute;
margin: 0;
padding: 0;
float: none;
}
nav#nav1 li:hover li {
float: none; }
nav#nav1 li:hover li a {
background-color: #69f;
border-bottom: 1px solid #fff;
color: #000; }
#navbar li li a:hover {
background-color: #8db3ff; }
nav#nav1 ul li a:hover { background: #686868 ; }
nav#nav1 ul li a:active { background: #F0F0F0; }
JavaScript functions for dropdown:
function DropDown2() {
var t = document.getElementById("Droplist2");
t.className = "DropDown";
}
function DropDown1() {
var t = document.getElementById("Droplist1");
t.className = "DropDown";
}
function DropUp2() {
var t = document.getElementById("Droplist2");
t.className = "DropUp";
}
function DropUp1() {
var t = document.getElementById("Droplist1");
t.className = "DropUp";
}
If you are wondering why I took such a difficult route for making the navigation bar, it's because I have to use JavaScript.
Here is JS fiddle example: http://jsfiddle.net/fNPvf/10015/
The window is small in the fiddle, and the effect is slightly different, but notice how when you hover over "Data Validation" the dropdown menu pushes the text/image/body downwards?

You need absolute positioning and a higher z-index for either the containing <div> or the <ul> itself. Just add this to your code and adjust the z-index as needed:
nav#nav1 ul{
position: absolute;
top: 0;
z-index: 9;
}

and here is the menu
<ul id="jsddm">
<li>About us
<ul>
<li>Mission
<ul>
<li>Mission Statment 1</li>
</ul>
</li>
<li> vision </li>
<li>status </li>
</ul>
</li>
<li> Contact
<ul>
<li>Office </li>
<li> Support </li>
</ul>
</li>
</ul>
as you can see the 3rd level "Mession Statment 1" doesn't appear, and that's my problem, any suggestion ???

The problem is maybe due to these lines
$('#jsddm > li').bind('mouseover', jsddm_open);
$('#jsddm > li').bind('mouseout', jsddm_timer);
in which you set an event handler only to the direct <li> children of #jsddm element. But your third <ul> is not contained in a such <li>, so try to change the above lines in
$('#jsddm li').bind('mouseover', jsddm_open);
$('#jsddm li').bind('mouseout', jsddm_timer);
and
function jsddm_open() {
...
ddmenuitem = $(this).children('ul:first').css('visibility', 'visible');}
