Find #ID, AddClass by URL in Navigation Jquery

I am making a website. I want to go from link to next page with ID. Like the following
Page Name: index.html
Rings
Page Name: collection.html
<ul class="nav navbar-nav" id="nav">
<li id="rings" class="active">Rings</li>
<li id="earrings">Earrings</li>
<li id="neckwears">Neckwear</li>
<li id="purses">Purses</li>
<li id="mini">Set an mini set</li>
</ul>
I try to take code and implement in this but not get any success.
<script type="text/javascript" charset="utf-8">
$(document).ready(function () {
$(function(){
var current = location.pathname;
var url = window.location.hash;
$('#nav li').each(function(){
var $this = $(this);
// if the current path is like this link, make it active
if($this.attr('href').indexOf(current) !== -1){
$this.addClass('active');
}
});
});
});
</script>
I wan to put active class automatically in #nav list via using URL # value.

You can just use the pathname as a selector, like this: $('#nav li#'+current)
There is no reason to loop through all of them.
$(document).ready(function() {
$(function() {
var current = "rings"; //location.pathname
$('#nav li#' + current).addClass("active");
});
});
.active a {
color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="nav navbar-nav" id="nav">
<li id="rings" class="">Rings</li>
<li id="earrings">Earrings</li>
<li id="neckwears">Neckwear</li>
<li id="purses">Purses</li>
<li id="mini">Set an mini set</li>
</ul>

You were just comparing to the wrong variable. Just change your code to the below
$(document).ready(function () {
$(function(){
var current = location.pathname;
var url = window.location.hash;
$('#nav li').each(function(){
var $this = $(this);
// if the current path is like this link, make it active
if("#" + $this.attr('id') == url){
$this.addClass('active');
}
});
});
});

Trying to add active class to menu item

I've spent 2 hours trying to create an active menu with no success, so I figured I would ask for help. I have an html menu, some js & css...
$(function() {
var pgurl = window.location.href.substr(window.location.href
.lastIndexOf("/") + 1);
$("#index li a").each(function() {
if ($(this).attr("href") == pgurl || $(this).attr("href") == '')
$(this).addClass("active");
})
});
.active { font-weight:bold;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='index'>
<div class='container'>
<div class='top'>
<h1><a href='/' title='The Maths Project'>The Maths Project</a></h1>
</div>
<ul class='section active_section' id='section_2'>
<li><span id='section_title_2' class='section_title'><a href='#' id='section_link_2'>Against the odds.</a></span>
<ul>
<li id='exhibit_106' class='exhibit_title'> → Introduction

</ul>

</ul>
<ul class='section' id='section_3'>
<li><span id='section_title_3' class='section_title'><a href='http://themathsproject.co.uk' id='section_link_3'>Remembering everything.</a></span>
<ul>
<li id='exhibit_104' class='exhibit_title'><a href='../against-the-odds/black-swans'>black swans</a>
</li>
<li id='exhibit_72' class='exhibit_title'><a href='../against-the-odds/in-here-it-is-yesterday'>in here it is yesterday </a>
</li>
</ul>
</li>
</ul>
</div>
</div>
When the user is on a specific page, the "a" link which they have clicked should become bold. However, for whatever reason it's not working.
I would greatly appreciate any help,
Regards,
Jack

I am not clear with your question but do you want set active class to menu, so you try the below code
$('#navlist a').click(function(e) {
e.preventDefault(); //prevent the link from being followed
$('#navlist a').removeClass('selected');
$(this).addClass('selected');
});
.nav {
color: green;
}
.selected {
color: red;
}
.san ul li{
float:left;
margin-right: 25px;
}
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.js"></script>
<div class="san">
<ul id="navlist">
<li><a class="nav" href="">Home</a></li>
<li><a class="nav" href="">About Us</a></li>
<li><a class="nav" href="">Services</a></li>
<li><a class="nav" href="">Contact</a></li>
</ul>
</div>

This line gets the page name:
var pgurl = window.location.href.substr(window.location.href
.lastIndexOf("/") + 1);
you need to apply the same logic to each of your links to see if they match:
$("#index li a").each(function() {
var aurl = $(this).attr("href").substr($(this).attr("href")
.lastIndexOf("/")+1);
if (aurl == pgurl || aurl == '')
$(this).addClass("active");
})
Snippet below (tweaked to match as location.href won't match)
$(function() {
//var pgurl = window.location.href.substr(window.location.href
// .lastIndexOf("/") + 1);
var locationhref = "mysite.com/against-the-odds/introduction"
var pgurl = locationhref.substr(locationhref.lastIndexOf("/")+1);
$("#index li a").each(function() {
var aurl = $(this).attr("href").substr($(this).attr("href")
.lastIndexOf("/")+1);
//console.log(aurl)
if (aurl == pgurl || aurl == '')
$(this).addClass("active");
})
});
.active { font-weight:bold;color:yellow;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='index'>
<div class='container'>
<div class='top'>
<h1><a href='/' title='The Maths Project'>The Maths Project</a></h1>
</div>
<ul class='section active_section' id='section_2'>
<li><span id='section_title_2' class='section_title'><a href='#' id='section_link_2'>Against the odds.</a></span>
<ul>
<li id='exhibit_106' class='exhibit_title'> → Introduction
</li>
<li id='exhibit_83' class='exhibit_title'><a href='../against-the-odds/deriving-functions'> → Deriving functions</a>
</li>
<li id='exhibit_83' class='exhibit_title'><a href='../against-the-odds/exploiting-odds'> → Exploiting odds</a>
</li>
</ul>
</li>
</ul>
<ul class='section' id='section_3'>
<li><span id='section_title_3' class='section_title'><a href='http://themathsproject.co.uk' id='section_link_3'>Remembering everything.</a></span>
<ul>
<li id='exhibit_104' class='exhibit_title'><a href='../against-the-odds/black-swans'>black swans</a>
</li>
<li id='exhibit_72' class='exhibit_title'><a href='../against-the-odds/in-here-it-is-yesterday'>in here it is yesterday </a>
</li>
</ul>
</li>
</ul>
</div>
</div>

Try following and check if it works.
$(function() {
var pgurl = window.location.href.substr(window.location.href.lastIndexOf("/") + 1);
$("#index li a").each(function() {
var href = "";
if($(this).attr("href") != '')
href = $(this).attr("href").substr(($(this).attr("href").lastIndexOf("/")+1);
if (href == pgurl || href == '')
$(this).addClass("active");
})
});

Just traverse the whole links and when any link will clicked then change the font-weight:normal to all links and then apply the font-weight:bold to currently clicked link.
$().ready(function () {
$("ul>li").click(function () {
$("ul>li").css("font-weight", "normal");
$(this).css("font-weight", "bold");
});
});

Add active class to nav li depending on url?

I'm having some real hard time adding class active to the li that contains the current page the site is on. URL = http://polissagethibodeau.com/
Here is the relevant HTML
<nav class="nav">
<ul class="sf-menu">
<li id="home">
Home
</li>
<li>
About us
</li>
<li>
Services
<ul>
<li>
Car, Truck and Vans
</li>
<li>
Semi, Boats, RV and Busses
</li>
<li>
Airplanes and Helicopters
</li>
<li>
Aluminum and Plexiglass polishing</li>
</ul>
</li>
<li>
Photos
</li>
<li>
Contact Us
</li>
</ul>
</nav>
CSS I am trying to apply
.sf-menu > li.active > a {
background: #c2e078;
}
Here is the script I am trying to use to no success.
$(function() {
var path = window.location.pathname.substring(1);
$('.nav>li>a[href="' + path + '"]').parent().addClass('active');
});

YOU can do it by two or many way. Example project
Source LINK
1.----
$(function() {
var pgurl = window.location.href.substr(window.location.href
.lastIndexOf("/")+1);
$("nav ul a").each(function(){
if($(this).attr("href") == pgurl || $(this).attr("href") == '' )
$(this).addClass("active");
})
});
2.----
here's the code if u want to use plain javascript
function setActive() {
aObj = document.getElementById('nav').getElementsByTagName('a');
for(i=0;i<aObj.length;i++) {
if(document.location.href.indexOf(aObj[i].href)>=0) {
aObj[i].className='active';
}
}
}
window.onload = setActive;
3.----
function setActive() {
$('#nav').find('a').each(function () {
//console.log(document.location.href)
if (document.location.href == "http://......" + $(this).attr('href')) {
$(this).parents("ul").removeClass("hidden-ul");
$(this).parents().addClass("active");
}
});
}
window.onload = setActive;

Use a if statement to check if it is in the url:
<script>
$(function() {
var path = window.location.pathname.substring(1);
if(window.location.href = path) {
$('.nav>li>a[href="' + path + '"]').parent().addClass('active');
}
});
</script>

Its because the HREF property of each of those links is going to be equal to a complete URL, not just file.php
You can get around this by using the $= operator which means (ends with)
Note in the DEMO I changed the var path assignment to just services.php so that it would work in the snippet.
Also, use the $(document).ready(function() { trigger to properly add a listener to an event
Note I realize that this example will cause all of the links to services.php to have the class active added to them. To get around this assign a custom class called navlink to each link in the navigation bar and then use
$('.navlink[href$="' + path + '"]:parent').addClass('active');
$(document).ready(function() {
//var path = window.location.pathname.substring(1);
var path = 'services.php#large';
$('a[href$="' + path + '"]:parent').addClass('active');
});
.active {
font-size: 1.75em;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<nav class="nav">
<ul class="sf-menu">
<li id="home">
<a href="./" >Home</a>
</li>
<li>
About us
</li>
<li>
Services
<ul>
<li>
Car, Truck and Vans
</li>
<li>
Semi, Boats, RV and Busses
</li>
<li>
Airplanes and Helicopters
</li>
<li>
Aluminum and Plexiglass polishing</li>
</ul>
</li>
<li>
Photos
</li>
<li>
Contact Us
</li>
</ul>
</nav>

$(document).ready(function () {
// Get previously stored url
if (sessionStorage.getItem("active-class-url"))
{
strLastUrl = sessionStorage.getItem("active-class-url");
$('.nav > li >a[href="' + strLastUrl + '"]').parent().addClass('active');
}
});
$(document).on(".nav > li > a", "click", function () {
// Remove active class from all ancher tag
$(".nav > li > a").parent("li").removeClass('active');
// Add active class to currenly clicked acnher tag
$(this).parent("li").addClass('active')
// Store value of active calss url. So on page refresh you can get it
sessionStorage.setItem("active-class-url", $(this).attr("href"));
})

The problem is your selector.
Instead of this:
$(".nav > li > a")
Use this:
$(".nav > ul > li > a")
Also remove the . (dot) before your paths, and this will work:
$(document).ready(function() {
var pathname = window.location.pathname;
$(".nav > ul > li > a").each(function() {
var $this = $(this);
if ($this.attr("href") === pathname) {
$this.parent().addClass("active");
}
});
});
Test:

$(document).ready(function() {
var url = window.location.toString();
$('#home a').attr('href',url)
$('#home a').text(url)
$('ul.sf-menu a').filter(function() {
if (this.href != '') {
if (this.href == url) {
console.log(this.href)
console.log(url)
$(this).addClass('active');
}
}
});
});
.active {
color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<nav class="nav">
<ul class="sf-menu">
<li id="home">
Home
</li>
<li id="stacksnippets">
stacksnippets
</li>
</ul>
</nav>
try above method I hope it helps you.

slideToggle remove other active classes

I have a simple menu/accordion slider. I want to add the class="active" to the clicked link and slide down to show the UL. When another separate menu item is clicked then the active class should be removed from the previous element and added to the one just clicked. Also if the same is clicked when in active mode then the slider should slide up and remove the active class.
I've tried various configurations of the below but each time have problems getting the active class to be removed if the same is clicked to slide up. Any help is appreciated.
$(document).ready(function(menuSlide) {
$('li.menu-item-has-children a').click(function () {
if ($('li.menu-item-has-children a').hasClass('active')) {
$('li.menu-item-has-children a').removeClass('active');
}
else {
$(this).addClass('active');
}
$(this).next('ul').slideToggle();
$(this).parent().siblings().children().next().slideUp();
return false;
});
});
Update - have created a quick JSFiddle that demonstrates the problem, apologies for not doing on opening question. You can see that if same item is clicked to toggle the state remains active.

Since you want to support toggling, you should not remove active class from current element so
$(document).ready(function(menuSlide) {
var $as = $('li.menu-item-has-children a').click(function() {
$(this).toggleClass('active').next('ul').slideToggle();
$(this).parent().siblings().children('ul').slideUp();
$(this).parent().siblings().children('.active').removeClass('active');
return false;
});
});
.menu-item-has-children ul {
display: none;
}
a.active {
color: green;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<ul>
<li class="menu-item-has-children">
<a>1</a>
<ul>
<li>1.1</li>
<li>1.2</li>
</ul>
</li>
<li class="menu-item-has-children">
<a>1</a>
<ul>
<li>1.1</li>
<li>1.2</li>
</ul>
</li>
<li class="menu-item-has-children">
<a>1</a>
<ul>
<li>1.1</li>
<li>1.2</li>
</ul>
</li>
</ul>

We simply store the previous click div in a variable and then slide up that div on click :
var previousElement = 0;
$(document).ready(function(menuSlide) {
$('li.menu-item-has-children a').click(function () {
if ($('li.menu-item-has-children a').hasClass('active')) {
$('li.menu-item-has-children a').removeClass('active');
previousElement = 0;
}else {
$(this).addClass('active');
if(previousElement != 0) {
$(previousElement).removeClass('active');
$(previousElement).slideUp();
}
previousElement = this;
}
});

Easiest way is,
$(document).ready(function(){
$('li.menu-item-has-children .content').slideUp();
$(document).on('click','li.menu-item-has-children a',function(e){
e.preventDefault();
$this = $(this);
$('li.menu-item-has-children a').removeClass('active');
$this.addClass('active');
$('li.menu-item-has-children a').parent().find('.content').slideUp();
$this.parent().find('.content').slideDown();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<html>
<ul>
<li class="menu-item-has-children">
A
<div class="content">
AAAA AAAA AAAA
</div>
</li>
<li class="menu-item-has-children">
B
<div class="content">
BBBB BBBB BBBB
</div>
</li>
<li class="menu-item-has-children">
C
<div class="content">
CCCC CCCC CCCC
</div>
</li>
</ul>
</html>

In below example, i've worked same link click twice, please let me know if you are requesting this thing or not,
$(document).ready(function(menuSlide) {
$('li.menu-item-has-children a').click(function () {
console.log($(this).hasClass('active'));
if($(this).hasClass('active') == false)
{
if ($('li.menu-item-has-children a').hasClass('active')) {
$('li.menu-item-has-children a').removeClass('active');
}
else {
$(this).addClass('active');
}
$(this).next('ul').slideDown();
$(this).parent().siblings().children().next().slideUp();
}
return false;
});
});

JQuery accordion menu with children and show active page

I want to create an accordion menu with jQuery which remembers the active page. Now i've got the following menu:
<nav id="secondary">
<ul id="nav">
<li class="tournament">
<a onclick="function">Belgie</a>
<ul class="sub" style="display: none;">
<li>
<li class="first">tournament1</li>
<li class="last">test</li>
</li>
</ul>
</li>
<li class="tournament">
<a onclick="function">Nederland</a>
<ul class="sub" style="display: none;">
<li>
<li class="first">Nedtournament1</li>
<li class="has_children current">
Nedtournament2
<ul class="dropdown">
<li class="first">subtournament2-1</li>
<li class="last current">subtournament2-2</li>
</ul>
</li>
<li>Nedtournament3</li>
<li class="last">Nedtournament3</li>
</li>
</ul>
</nav>
Im using the following jQuery, it sets a cookie to determine on which page we are and which menu should be expanded. This works, but not for the children pages.
// creatie cookie
$('#nav > li > a').click(function(){
var navIndex = $('#nav > li > a').index(this);
$.cookie("nav-item", navIndex);
$('#nav li ul').slideUp();
if ($(this).next().is(":hidden")){
$(this).next().slideUp();
} else {
$(this).next().slideToggle();
}
$('#nav li a').removeClass('active');
$(this).addClass('active');
});
// use cookie value
var checkCookie = $.cookie("nav-item");
if (checkCookie != "") {
$('#nav > li > a:eq('+checkCookie+')').next().show();
}
// complete jquery
$(document).ready(function () {
var checkCookie = $.cookie("nav-item");
if (checkCookie != "") {
$('#nav > li > a:eq('+checkCookie+')').next().show();
}
$('#nav > li > a').click(function(){
var navIndex = $('#nav > li > a').index(this);
$.cookie("nav-item", navIndex);
$('#nav li ul').slideUp();
if ($(this).next().is(":visible")){
$(this).next().slideUp();
} else {
$(this).next().slideToggle();
}
$('#nav li a').removeClass('active');
$(this).addClass('active');
});
});
does anyone know how I can add the cild pages to they expand when I click them? And they keep expanded when i reload the page.
