Add Active Navigation Class Based on URL - javascript

I'm trying to add an active class (i.e. class="active") to the appropriate menu list item based upon the page it is on once the page loads. Below is my menu as it stands right now. I've tried every snippet of code I could find in this regard and nothing works. So, can someone please explain simply where and how to add in javascript to define this task?
<ul id="nav">
<li id="navhome">Home</li>
<li id="navmanage">Manage</li>
<li id="navdocso">Documents</li>
<li id="navadmin">Admin Panel</li>
<li id="navpast">View Past</li>
</ul>
Here is an example of the javascript that I'm putting in my head tag in my site master. What am I doing wrong?
$(document).ready(function () {
$(function () {
$('li a').click(function (e) {
e.preventDefault();
$('a').removeClass('active');
$(this).addClass('active');
});
});
});

The reason this isn't working is because the javascript is executing, then the page is reloading which nullifies the 'active' class. What you probably want to do is something like:
$(function(){
var current = location.pathname;
$('#nav li a').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');
}
})
})
There are some cases in which this won't work (multiple similarly pointed links), but I think this could work for you.

jQuery(function($) {
var path = window.location.href; // because the 'href' property of the DOM element is the absolute path
$('ul a').each(function() {
if (this.href === path) {
$(this).addClass('active');
}
});
});
.active, a.active {
color: red;
}
a {
color: #337ab7;
text-decoration: none;
}
li{
list-style:none;
}
<h3>Add Active Navigation Class to Menu Item</h3>
<ul>
<li>Home</li>
<li>About</li>
</ul>
<h2>Live Demo</h2>

With VANILLA plain JavaScript
(function () {
var current = location.pathname.split('/')[1];
if (current === "") return;
var menuItems = document.querySelectorAll('.menu-item a');
for (var i = 0, len = menuItems.length; i < len; i++) {
if (menuItems[i].getAttribute("href").indexOf(current) !== -1) {
menuItems[i].className += "is-active";
}
}
})();

ES6 version, that works properly in cases when your link is to "/products" and you have subroutes, like: "/products/new", "/products/edit", etc.
let switchNavMenuItem = (menuItems) => {
var current = location.pathname
$.each(menuItems, (index, item) => {
$(item).removeClass('active')
if ((current.includes($(item).attr('href')) && $(item).attr('href') !== "/") || ($(item).attr('href') === "/" && current === "/")){
$(item).addClass('active')
}
})
}
$(document).ready(() => {
switchNavMenuItem($('#nav li a, #nav li link'))
})

If your menu need add the active class in li, you need use this code above.
$(function($) {
let url = window.location.href;
$('nav ul li a').each(function() {
if (this.href === url) {
$(this).closest('li').addClass('active');
}
});
});

$(function() {
var CurrentUrl= document.URL;
var CurrentUrlEnd = CurrentUrl.split('/').filter(Boolean).pop();
$( ".top-menu li a" ).each(function() {
var ThisUrl = $(this).attr('href');
var ThisUrlEnd = ThisUrl.split('/').filter(Boolean).pop();
if(ThisUrlEnd == CurrentUrlEnd)
$(this).addClass('active')
});
});

This on page JS code is a 100% working put your id and enjoy it.
<script src="https://code.jquery.com/jquery-3.3.1.js"></script>
<script>
$(document).ready(function() {
var CurrentUrl= document.URL;
var CurrentUrlEnd = CurrentUrl.split('/').filter(Boolean).pop();
console.log(CurrentUrlEnd);
$( "#lu-ID li a" ).each(function() {
var ThisUrl = $(this).attr('href');
var ThisUrlEnd = ThisUrl.split('/').filter(Boolean).pop();
if(ThisUrlEnd == CurrentUrlEnd){
$(this).closest('li').addClass('active')
}
});
});

None of the above solutions worked for me. Finally this javascript solution worked.
<script>
function setActive() {
linkObj = document.getElementById('premier-topnav').getElementsByTagName('a');
for(i=0;i<linkObj.length;i++) {
if(document.location.href.indexOf(linkObj[i].href)>=0) {
linkObj[i].classList.add("active");
}
}
}
window.onload = setActive;
</script>
premier-topnav is the id of navbar div.
.active class is defined as:
#premier-topnav .active {
color: brown;
}

var cururl = window.location.pathname;
var curpage = cururl.substr(cururl.lastIndexOf('/') + 1);
var hash = window.location.hash.substr(1);
if((curpage == "" || curpage == "/" || curpage == "admin") && hash=="")
{
//$("nav .navbar-nav > li:first-child").addClass("active");
}
else
{
$(".topmenu li").each(function()
{
$(this).removeClass("active");
});
if(hash != "")
$(".topmenu li a[href*='"+hash+"']").parents("li").addClass("active");
else
$(".topmenu li a[href*='"+curpage+"']").parents("li").addClass("active");
}

Rob.M got it right.
I'm just going to post my solution since his didn't really work for me. i have a small change in comparison to him. assuming you have different paths to each link.
(function() {
var current = location.pathname;
$('#navbar ul li a').each(function() {
var $this = $(this);
// we check comparison between current page and attribute redirection.
if ($this.attr('href') === current) {
$this.addClass('active');
}
});
})();

This worked perfectly for me.
$(function($) {
let url = window.location.href;
$('nav ul li a').each(function() {
if (this.href === url) {
$(this).addClass('active');
}
});
});

I know it been quite a while this question was asked. Here is the answer which will work without jQuery:
var activeNavlink = document.querySelectorAll('nav a[href^="/' + location.pathname.split("/")[1] + '"]');
activeNavlink[0].classList.add('active');
Hope this helps.

If you want for master page in asp .net just put this code inside body tag
<script type="text/javascript">
jQuery(function ($) {
var path = window.location.href; // because the 'href' property of the DOM element is the absolute path
$('ul a').each(function () {
if (this.href === path) {
$(this).addClass('active');
}
});
});
</script>
Thank you

This should do your job in one liner.
document.querySelector(`a[href^='${location.pathname.split('/'[1])}']`).className = 'active'

jQuery style:
$('a[href="'+ window.location.href + '"]').css({
backgroundColor: 'red',
color: 'white'
})
In first line use this if you have relative links
$('a[href="'+ window.location.path + '"]').css({
Or both
$('a[href="'+ window.location.href + '"], a[href="'+ window.location.path + '"]').css({

$(function(){
//this returns the whole url
var current = window.location.href;
//this identifies the list you are targeting
$('#nav li a').each(function(){
var $this = $(this);
// if the current path is exactly like this link, make it active
if($this.attr('href') === current){
//this takes care of ul inside a ul, it opens and make active the selected li
$this.parents('.dropdown-menu').toggle();
$this.css('color', 'red');
}
})
});

The bellow jquery script will match the manu if the page has any query string parameter as well. This script is helpful for links with nearly same name.
<script>
//select current menu Item
$(function () {
var current = location.pathname.toLocaleLowerCase();
$('.sidebar li a').each(function () {
var $this = $(this);
var href = $this.attr('href');
href = href.replace(/\?.*/, "").toLocaleLowerCase();
// if the current path is equal to this link, make it active
if (href === current) {
$this.addClass('active');
}
})
})
</script>

Accessible Version:
Here's an accessible version inspired by rob.
I didn't want to run this script on the homepage so I check if it's the homepage
I check if the link matches the exact page instead of checking if it's included in the path. Or else you would get multiple items in the query.
JS
function activateCurrentPage(menuItems){
var current = location.pathname;
if (current !== "/") {
menuItems.each(function(){
var $this = $(this);
if($this.attr('href') === current){
$this.addClass('active');
$this.attr('aria-current', 'page');
}
});
};
}
activateCurrentPage( $('#nav li a') );
CSS
Then for CSS don't target the active class instead target the aria attribute.
#nav a[aria-current="page"]{
color:red;
}

Saw somethng wth plain Javascript
https://www.youtube.com/watch?v=BI3kNsTruWo&ab_channel=OnlineTutorials
Put it in <script> tags after header in my Wordpress site
(function () {
const currentLocation = location.href;
console.log(currentLocation);
const menuItem = document.getElementsByClassName('nav-item');
const menuLength = menuItem.length
for ( i = 0; i < menuLength; i++){
if(menuItem[i].href === currentLocation){
menuItem[i].className += " active"
}
}
})();
<a class="nav-item" href="/ideja/">Ideja</a>
<a class="nav-item" href="/piesaki-sapni/">Piesaki Sapni</a>
<a class="nav-item" href="/uznemejiem/">Uzņēmējiem</a>
<a class="nav-item" href="/sapnu-banka/">Sapņu banka</a>
<a class="nav-item" href="/sapnus-atbalsta/">Sapņus atbalsta</a>
<a class="nav-item" href="/99-iedvesmas-stasti/">99 iedvesmas stāsti</a>
<a id="lv" class="active" href="#">LV</a>
<a href="javascript:void(0);" class="icon" onclick="openNavbar()">
<div id="hamburger" class="hamburger "></div>
</a>

i was having troubles where the link to the root would light up if any page was selected when using Networker's example. this will prevent that for the root pae:
function setActive() {
linkObj = document.getElementById('menu').getElementsByTagName('a');
for(i=0;i<linkObj.length;i++) {
const url = new URL(window.location.href);
if((document.location.href.indexOf(linkObj[i].href)>=0 && linkObj[i].href != url.protocol+"//"+url.hostname+"/") || document.location.href == linkObj[i].href) {
linkObj[i].classList.add("active");
}
}
}
window.onload = setActive;

This Does the Job Done For me...
Put this before the ending of body tag
$(function () {
var current = location.pathname;
console.log(current);
if (current == "/") {
$('#home').addClass('active'); //#home is the id for root link.
}
else {
$('#navbarCollapse div a').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');
}
})
}
})

Classes can make the life a whole way easier.
css
<nav>
<ul class="nav-list">
<li class="nav-list-item"><a class="nav-link nav-link-active" href="index.html">Home</a></li>
<li class="nav-list-item"><a class="nav-link" href="about.html">About Me</a></li>
<li class="nav-list-item"><a class="nav-link" href="posts.html">Recent Posts</a></li>
</ul>
</nav>
js
(function() {
current_page = window.location.href;
navlinks = document.getElementsByClassName("nav-link");
active_page = document.getElementsByClassName("nav-link-active")[0];
if (active_page) {
active_page.classList.remove("nav-link-active");
}
for (i=0; i < navlinks.length; i++) {
if (navlinks[i].href == current_page) {
navlinks[i].classList.add("nav-link-active");
break;
}
}
})();

I know this is late answer but this works ok for me
var links = document.querySelectorAll('li a');
for (link of links) {
if (window.location.pathname == link.getAttribute('href')) {
link.classList.add('active')
} else {
link.classList.remove('active')
}
}

Below is the solution to add the dynamic active class to the navbar elements.
// first lets get all the navbar elements.
const navElements = document.querySelectorAll(".list");
// creating a function of active navbar item
const activeLink = (el) => {
list.forEach((item) => {
item.classList.remove("active");
el.classList.add("active");
});
};
// attaching the event listener for each element
list.forEach((item) => {
item.addEventListener("click", () => {
activeLink(item)
});
});

Set selected navigation option using window.location

I have a theme that sets the selected left navigation option based on what URL you are visiting. However, it breaks if the is a variable attached to the URL, for example www.test.com/abc.aspx?delete=1. The URL www.test.com/abc.aspx works fine and sets the link ABC to active.
I have tried to modify the code to cut off everything after and including ?, but it won't work as intended (nothing in the NAV is selected).
ORIGINAL CODE:
$(function () {
var url = window.location;
var element = $('ul#sidebarnav a').filter(function () {
return this.href == url;
}).addClass('active').parent().addClass('active');
while (true) {
if (element.is('li')) {
element = element.parent().addClass('in').parent().addClass('active');
}
else {
break;
}
}
});
MY EDITED CODE:
$(function () {
var url = window.location.toString();
var url_fix = url.split('?');
var element = $('ul#sidebarnav a').filter(function () {
return this.href == url_fix[0];
}).addClass('active').parent().addClass('active');
while (true) {
if (element.is('li')) {
element = element.parent().addClass('in').parent().addClass('active');
}
else {
break;
}
}
});
I think it is the line with "return this.href == url_fix[0];" that is the culprit.
SOLUTION (what I came up with after reading the comments, thanks guys):
$(function () {
var url = location.href.split("/").slice(-1).toString();
var url_fix = url.split('?');
var element = $('ul#sidebarnav a').filter(function () {
return $(this).attr("href") == url_fix[0];
}).addClass('active').parent().addClass('active');
while (true) {
if (element.is('li')) {
element = element.parent().addClass('in').parent().addClass('active');
}
else {
break;
}
}
});
Try comparing pathnames instead.
var element = $('ul#sidebarnav a').filter(function () {
return this.pathname == location.pathname;
}).addClass('active').parent().addClass('active');
For example on this page location.pathname returns:
"/questions/48234042/set-selected-navigation-option-using-window-locaiton/48234196"
and does not include location.hash or location.search
I used the answer by #vbguyny to solve the issue. Had to add location.href.split("/").slice(-1).toString(); to get the actual page name, but after that it worked fine. Thanks!

jQuery toggle menu items and sheet

I have written code that works very well, but unfortunately it is not perfect functional. I will describe briefly the action:
When I click on '.navbar-nav li a' parent and '.sheets, .sheetsBg' get active class.
If I click again '.navbar-nav li a' is properly removed only for the menu item parent class.
code:
function manageSheetsToggle() {
var navMenuItem = '.navbar-nav li a';
$(navMenuItem).click(function (e) {
if (!isTabletResolution() && !isPhoneResolution()) {
{
var sheetId = $(this).parent().data('target');
if ($('.sheets, .sheetsBg').hasClass('active')) {
$('.sheets, .sheetsBg').removeClass('active');
}
e.preventDefault();
$(this).parent().toggleClass('active').siblings().removeClass('active');
$("#" + sheetId).toggleClass('active').siblings().removeClass('active');
$(".sheets, .sheetsBg").addClass("active");
}
} else {
$(navMenuItem).click(function (e) {
e.preventDefault();
location.href = $(this).attr('href');
}
);
}
});
$('.sheetsBg, .corpoBelt, .header').click(function () {
$(".sheets, .sheetsBg").removeClass("active");
});
}
pls help.
I hope this is what you are luking for. I changed your code a little bit, but it works fine now. Try it and let me know
<script type="text/javascript">
var sheet, ln, cn = 0;
$(document).ready(function () {
$("#toggleMenu").find("a").on("click", function (e) {
ln = $(this);
sheet = ln.parent().data('target');
$("#" + sheet).toggleClass("active").siblings().removeClass('active');
$(".sheets").find("section").each(function () {
if ($(this).hasClass("active"))
cn++;
});
if (cn) {
$(".sheets").addClass('active');
cn = 0;
} else
$(".sheets").removeClass('active');
});
$('.corpoBelt').click(function () {
$(".sheets").removeClass("active");
});
});
</script>
I think you can use siblings() selector more easier

sort li elements using javascript or jquery

In my page i have the the folowing. I need to sort it out using javascript.
<li class="cat2 lang1">Hello</li>
<li class="cat2 lang1">Hello</li>
<li class="cat1 lang2">Hello</li>
<li class="cat3 lang3">Hello</li>
what i tried is:
$('#movieFeatureFilter span#selGenre .subMenus li').click(function()
{
if(this.id != '')
{
$('.movie_lists ul li').hide();
$('.movie_lists ul li.cat'+this.id).show();
}
else $('.movie_lists ul li').show();
});
this works perfect. but what i need to sort the list using the combination of lang and cat.
ie if i select cat1 as category and lang2 as language then it might show the third li
i think you got wht i mean. sorry for the bad explanention. help me pls
var $items = $('ul li'), $cat = $('#cat'), $lang = $('#lang');
$('#cat, #lang').change(function(){
var cat = $cat.val(), lang = $lang.val(), $filtered = $items;
if(cat){
$filtered = $filtered.filter('.' + cat);
}
if(lang){
$filtered = $filtered.filter('.' + lang);
}
$items.not($filtered).hide();
$filtered.show()
})
Demo: Fiddle
Seems instead of sorting you want to show/hide items based on selection of cat and lang. Following function will serve your purpose:
$("#movieFeatureFilter span#selGenre .subMenus li").click(function () {
/*GET cat AND lang FROM DROPDOWNS*/
var cat = $("#c").val(),
lng = $("#l").val();
$("#<ID OF UL> li").filter(function () {
$this = $(this);
if ($this.hasClass(cat)) {
if (!$this.hasClass(lng)) {
$this.hide();
} else {
$this.show();
}
} else {
$this.hide();
}
});
});

Help With URL parameter to open tabs info

Need some help with the script below. I would like to add the ability to pass a url parameter that would open one of the tabs based on the URL#tabinfo. Any help would be great thanks.
(function ($) {
function getactTabAnc() {
return this.find('.active>a')[0];
}
function getContentId(tabAnchorS) {
return $(tabAnchorS).attr('href').replace('#', '');
}
function applyStyles(newActTabAnc) {
var actTabAnc = newActTabAnc || getactTabAnc.apply(this), activeContentId = getContentId(actTabAnc);
this.find('a').each(function () {
var $cur = $(this), curContentId = getContentId(this);
if (activeContentId === curContentId) {
$cur.closest('li').addClass('active');
$('#' + curContentId).show();
}
else {
$cur.closest('li').removeClass('active');
$('#' + curContentId).hide();
}
});
}
$.fn.tabs = function () {
return this.each(function () {
var $tabTainer = $(this);
applyStyles.apply($tabTainer);
$tabTainer.find('a').click(function (e) {
console.log('clicked');
var actTabAnc = getactTabAnc.apply($tabTainer), isActive = this === actTabAnc;
e.preventDefault();
if (!isActive) {
applyStyles.apply($tabTainer, [this]);
}
});
});
};
})(jQuery);
<ul id="tabsHolder">
<li class="active">Header 1</li>
<li>Header 2</li>
</ul>
<div id="tabId1">Content 1</div>
<div id="tabId2">Content 2</div>
Look at window.location.hash and onhashchange event. If ('onhashchange' in window) is false then you need to poll for the hash changing.
There exists libraries to abstract this away.

Cookies and javascript navigation (tabs)

I have a navigation tabs and when user clicks a tab the div changes with ajax. I would like to it to remember on what tab user was when user changes page. I havent done the tab navigation and im totally new to javascript/jquery. Here is the javascript for the tabs:
jQuery('#contentContainer #tabNavi .nav-item').each(function(i, item) {
jQuery(item).bind('click', function() {
if (jQuery('a', this).hasClass('activeTab')) {
return;
} else {
jQuery('#contentContainer #tabNavi .nav-item' a').removeClass('activeTab').eq(i).addClass('activeTab');
channel_id = jQuery('a', this).attr('href').split('#')[1];
if (channel_id == _channel) {
return;
}
}
})
});
The nav links are like this:
<li>Link1</li>
<li>Link2</li
Now I have the href value saved in a cookie but i dont know how can i change the active class to right li item when user comes on page and he has been on site before and he has clicked some tab.
Put this code after click event initialization (jQuery(item).bind('click', function() {...})
var selectedTab = $.cookie('selectedTab');
if (selectedTab) {
$('li[href="' + selectedTab + '"]').click();
}
UPD
A bit modified code
(function($) {
$('#contentContainer #tabNavi .nav-item a').click(function() {
var $link = $(this);
$link.click(function() {
if (!$link.hasClass('activeTab')) {
$('#contentContainer #tabNavi .nav-item a.activeTab').removeClass('activeTab');
$link.addClass('activeTab');
$.cookie('selected-tab', $link.attr('href'));
}
return false;
});
});
var selectedTab = $.cookie('selected-tab');
if (selectedTab) {
$('#contentContainer #tabNavi .nav-item a[href="' + selectedTab + '"]').click();
}
})(jQuery);
