jQuery click() and on() function - javascript

I'm trying to add "active" class to menu when user clicks on the button but for some reason it's not working correctly. They have to click really fast and two times. I've tried both click and on click function but still not working.
$('#menu li').click(function() {
$('#menu li.active').removeClass('active');
$(this).addClass('active');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav navbar-right" id="menu">
<li class="nav active">Home
</li>
<li class="nav">About
</li>
<li class="nav">Services
</li>
<li class="nav">Gallery
</li>
<li class="nav">Contact
</li>
</ul>
</div>

you must handle active li after page loaded.Add this at the end of your code:
var curruntLocation = window.location.href;
$('#menu li a').each(function ()
{
var thisHref = $(this).attr('href');
if (curruntLocation.indexOf(thisHref) > 0)
{
$(this).parent().addClass('active');
}
});

The links included in the menu items are reloading the page while clicking and when the page is reloaded, the initial setting comes first. You can use preventDefault() if you'd like to run the function but then, your links won't work.
I suggest you use anchors instead of query string.

How to collapse a submenu when clicked again

I'm relatively new to JS and I can't figure out how to close a submenu when clicked again (or if anything else is clicked, like the button which makes the menu appear.
With this thread here on Stackoverflow I managed to open the submenu on click on the parent, but how can i close it again by click it again? Other threads that I found by google didn't help me at all...
HTML
<ul id="menu">
<li>Home</li>
<li>In the news
<ul>
<li>Youtube</li>
<li>Blog</li>
</ul>
</li>
<li>Who's Who?
<ul>
<li>Youtube</li>
<li>Tackle Hunger Tackle Hunger</li>
</ul>
</li>
<li>Services Offered</li>
JS
function initMenu() {
$('#menu ul').hide();
$('#menu li a').click(
function() {
$('#menu ul').hide('normal');
$(this).next().slideToggle('normal');
});
}
$(document).ready(function() {
initMenu();
});
When I click it again, it closes and then opens up again... Really thanks a lot for helping me with this problem!
Here is also the jsfiddle of the other thread
Simply add an if and check if the next element is hidden.
Without the if, you will trigger hide and show twice by clicking on the same element.
function initMenu() {
$('#menu ul').hide();
$('#menu li a').click(function() {
$('#menu ul').hide('normal');
// check if the next element is hidden
if($(this).next().is(":hidden")) {
$(this).next().slideToggle('normal');
}
});
}
$(document).ready(function() {
initMenu();
});

HTML JS - sub menu is not working?

I'm trying to achieve this. But I could not succeed so far. My code is given below. What is wrong with it?
html:
<nav id="bt-menu" class="bt-menu">
<a href="#" class="bt-menu-trigger" id="bt-icon icon-gplus" ><br><span>Menu
<ul >
<li style="text-align:center;"><span>DashBoard</span></li>
<li style="text-align:center;"><span>User </span></li>
<li style="text-align:center;"><span>Candidates</span></li>
<li style="text-align:center;"><span>Partylist</span></li>
<li style="text-align:center;"><span>Position</span></li>
<li style="text-align:center;"><span>Program</span></li>
<li style="text-align:center;"><span>Department</span></li>
<li style="text-align:center;"class="active"><span>School-Year</span></li>
<li style="text-align:center;"><span>Reports</span></li>
<li style="text-align:center;"><span>Logs</span>
<ul class="sub-menu" style="text-align:right">
<li>Submenu</li>
</ul></li>
</ul>
</nav>
Javascript:
<script type="text/javascript">
$('li a').click(
function() {
$(this).next().slideToggle();
})
</script>
Firstly correct your markup ,some tags are not properly closed.
Second, you need to use preventDefault() to disable the default action of the a tag.
Third,
$('li a').click(
function() {
$(this).next().slideToggle();
})
this code will toggle you menu only if next element is the menu itself.
so use this
$('li a').click(function(e) {
e.preventDefault();
$('a:contains(Submenu)').slideToggle();
});

jquery tabs with links remember last active item

I did the following code, to be able to change the class of an li tag and then change the CSS of it.
I created a cookie variable that help me to select the good li tag. but I have a gap when I click.
I have three tabs : device, links and sites.
for example if I click on devices and had click on sites before, sites will be selected.
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('.tabs .tab-links a').on('click', function(e) {
jQuery.cookie("select", jQuery(this).parent('li').attr('id'));
});
jQuery('#' + jQuery.cookie("select")).addClass('active').siblings().removeClass('active');
});
</script>
<div class="tabs" >
<ul class="tab-links">
<li id="device">Devices</li>
<li id="link">Links</li>
<li id="site">Sites</li>
</ul>
</div>
Since clicking the link takes you to a new page, there is no need to do this programmatically.
The page /netmg/controller/device/search should have
<li id="device" class="active">...</li>
<li id="link">...</li>
<li id="site">...</li>
The page /netmg/controller/link/search should have
<li id="device">...</li>
<li id="link" class="active">...</li>
<li id="site">...</li>
The page /netmg/controller/site/search should have
<li id="device">...</li>
<li id="link">...</li>
<li id="site" class="active">...</li>
You can put that in the HTML.
If, instead, you want to make it all one page and the href attribute indicates what content is displayed, say, in a <div id="deviceContent"></div> or similar, you could use this:
<script>
jQuery(document).ready(function() {
jQuery('.tab-links li a').click(function(e){
e.preventDefault();
var newdiv = jQuery(this).attr('href');
jQuery('.tab-links li').removeClass('active');
jQuery(this).parent('li').addClass('active');
jQuery('.contents div').hide();
jQuery(newdiv).show()
});
});
</script>
<div class="tabs" >
<ul class="tab-links">
<li id="device" class="active">Devices</li>
<li id="link">Links</li>
<li id="site">Sites</li>
</ul>
</div>
<div class="contents">
<div id="deviceContent"><!-- insert some contents -->a</div>
<div id="linkContent"><!-- insert some contents --> b</div>
<div id="siteContent"><!-- insert some contents -->c</div>
</div>

Updated Javascript but not working
<script type='text/javascript'>//<![CDATA[
window.onload=function(){
$(document).ready(function () {
var index = Cookies.get('active');
$('.secondary').find('a').removeClass('active');
$(".secondary").find('a').eq(index).addClass('active');
$('.secondary').on('click', 'li a', function (e) {
e.preventDefault();
$('.secondary').find('a').removeClass('active');
$(this).addClass('active');
Cookies.set('active', $('.clearfix a').index(this));
});
});
}//]]>
</script>
You will definitely store somewhere the data, wich was the last active tab. If you want to do this on client side only, one solution can be the cookies. See here: How do I set/unset cookie with jQuery?
If you are using HTML5, then you can use web storage. See here.
If you are rendering your page by PHP, you can use $_SESSION variable for this. When user clicks a tab, you make an ajax request, and store the value of the active tab in a $_SESSION variable, but as i see, you want to do it on the client side.
UPDATE
Ok, i just created it for you.
First thing is to set an id for every a element in my example, to know, wich is that. You can do it some other way, but now this is the most simple.
Second is to download the jquery.cookie.js, and do not use the URL, store it locally.
Third, here could be a problem, if cookies are disabled on the client machine.
You need to do something like this:
HTML
<div role="navigation" id="navPrimary">
<ul class="secondary">
<li>Home</li>
<li>Account Menu
<ul>
<li>OVERVIEW</li>
</ul>
</li>
</ul>
</div>
CSS
.active {font-weight: bold; color: #F00}
JQUERY
ok, stacoverflow does not allow me to paste here a code but i loaded here the
https://raw.githubusercontent.com/carhartl/jquery-cookie/master/src/jquery.cookie.js script also!
<script type='text/javascript'>
$(function() {
//$.removeCookie("active");
var activeMenu = $.cookie("active");
console.log(activeMenu);
if (typeof activeMenu === 'undefined') {
$("#home").addClass("active");
} else {
$('#' + activeMenu).addClass('active');
}
$('li a').click(function(e) {
e.preventDefault();
var listItems = $("#navPrimary li a");
listItems.each(function(idx, li) {
$(li).removeClass('active');
});
$(this).addClass('active');
var id = $(this).attr('id');
$.cookie("active", id);
});
})
</script>

Slide Toggle automatically open the first item?

I have aJQuery accordian using the following JS.
function initMenu() {
$('#accordion ul').hide();
$('#accordion li a').click(
function() {
$(this).next().slideToggle('normal');
}
);
}
$(document).ready(function() {initMenu();});
And the following HTML
<ul id="accordion">
<li><a class="firstheading" href="#">Making words work</a>
<ul class="panelContent">
<li>
<p>IPSUM</p>
</li>
</ul>
</li>
<li><a class="heading" href="#">Full business-writing services</a>
<ul class="panelContent">
<li>
<p>IPSUM<p>
</li>
</ul>
</li>
</ul>
Can anyone tell me how to ensure the first item is opened when the page loads?
You can use the gt selector to specify the ul's with an index greater than zero, so every ul except the first.
Demo here
function initMenu() {
$('#accordion ul:gt(0)').hide();
$('#accordion li a').click(
function() {
$(this).next().slideToggle('normal');
}
);
}
$(document).ready(function() {initMenu();});
It should be opening automatically, but you can open up accordion pieces programmatically like so:
.accordion( 'activate' , index )
so to open up the first section, you would do
$('#accordion').accordion('activate',0);
You could put that in your document ready function. Note that a selector can also be used in place of the number, which represents each section from 0 onwards.
