I have included a header to my files as in include. In the header is the nav bar.
How do I, using jQuery, apply class="active" to the relevant li.
The only way I could think of doing it is to set a variable on the actual pages, apply an id that is equal to that variable of the relevant page and if function so if they match apply a class to the li.
However, I thought there must be a simpler way of achieving this.
<ul class="nav nav-pills right" id="div">
<li id="home" class="active">
Home
</li>
<li id="search">
Search
</li>
<li id="contact">
Contact
</li>
</ul>
An easy way to do this would be to have a script per page:
$('#home').addClass('active'); // for home page
You could try and match the href to the current url:
var path = window.location.pathname.substring(1);
$('.nav>li>a[href="' + path + '"]').parent().addClass('active');
More compact way:
$(function(){
var sPath = window.location.pathname;
var sPage = sPath.substring(sPath.lastIndexOf('/') + 1);
$('a[href="'+ sPage +'"]').parent().addClass('active');
});
As soon as the page loads it will run this code:
$(document).ready(function(){
$('li').removeClass('active');
$('li a').each(function() {
$found = $.contains($(this).prop("href"),location.pathname);
if ($found) {
$(this).closest('li').addClass('active');
break;
}
});
});
OR
You can also do this using regex :
$(document).ready(function(){
$('li').removeClass('active');
var regex = /[a-z]+.php/g;
var input = location.pathname;
if(regex.test(input)) {
var matches = input.match(regex);
$('a[href="'+matches[0]+'"]').closest('li').addClass('active');
}
});
You might need to have the similar id name to that of php file.
Check the demo here : Demo
You can do this:
//remove the active class from all items, if there is any
$('.nav>li').removeClass('active');
//finally, add the active class to the current item
$('a[href='+ location.pathname.substring(1) +']').parent().addClass('active');
You could use javascript to find the current list item based on the url, by adding the class to the right list item after the DOM has been loaded (e.g. string manipulation of window.location together with JQuery selectors and addClass())
I found a routine to set active (current) class on my shared menu, but I need to modify it to set the parent link only, and not the 'closest' link. It works great on menu items with no sub menus, but when a sub menu item is clicked, there is not indication on the main menu after page load. (the code I need to modify is below)
(function( $ ) {
$.fn.activeNavigation = function(selector) {
var pathname = window.location.pathname
var extension_position;
var href;
var hrefs = []
$(selector).find("a").each(function(){
// Remove href file extension
extension_position = $(this).attr("href").lastIndexOf('.');
href = (extension_position >= 0) ? $(this).attr("href").substr(0, extension_position) :
$(this).attr("href");
if (pathname.indexOf(href) > -1) {
hrefs.push($(this));
}
})
if (hrefs.length) {
hrefs.sort(function(a,b){
return b.attr("href").length - a.attr("href").length
})
hrefs[0].closest('li').addClass("current")
}
}; })(jQuery);
If someone still checks on google how to do it here is my solution
var path = window.location.href; // full url
$('a[href="'+ path +'"]').parent().addClass('active'); // find by selector url
HTML
<ul class="navbar-nav mr-auto">
<li class="nav-item">
<a class="nav-link" href="http://example.com/">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="http://example.com/history"> History</a>
</li>
</ul>

i put JQuery in my footer, it's having bug like when i click on notes home and notes both section get active please help any on
<script>
$(function () {
setNavigation();
});
function setNavigation() {
var path = window.location.pathname;
path = path.split('/');
path = path[path.length-1];
$(".menu--iris .navbar-nav li a").each(function () {
var href = $(this).attr('href');
href = href.split('/');
href = href[href.length-1];
if (path === href) {
$(this).parent('li').addClass('menu__item--current');
}
});
}
</script>
your HTML for the HOME link looks like:
<li class="menu__item menu__item--current">
Home
</li>
the menu__item--current class is hardcoded here, inserted in PHP file. As #VSM and #jackjop correctly noticed, you should remove this class and let jQuery to decide where to add it:
<li class="menu__item">
Home
</li>
you can also remove this hardcoded class in your JS code:
$(".menu--iris .navbar-nav li.menu__item--current").removeClass('menu__item--current');
$(".menu--iris .navbar-nav li a").each(function () {
...
});
BUt the best solution I think would be to print this class in your PHP code (since you already do it for the HOME link)
also, I noticed that you have a trailing slash in your Easy Notes image link:
<h1>
<a class="navbar-brand" href="https://easyfreenotes.in/index.php/Site/">
<i>E</i>
<span>asy-Notes</span>
</a>
</h1>
I would recommend to remove this slash:
<a class="navbar-brand" href="https://easyfreenotes.in/index.php/Site">
because, your jquery code checks only last fragment of your URL against HREF, so /index.php/Site/ may be equal to /index.php/Site/paper/
Use below code and replace your home page list item in header file.
<li class="menu__item">Home</li>
If you need any help let me know.
Thanks.
I'm using MetisMenu, when I have a link on a third layer menu item the parent menu items all collapse once the link has been clicked.
The second level menu itme links work correctly.
My sample code is here:
<div class="navbar-default sidebar" role="navigation">
<div class="sidebar-nav navbar-collapse">
<ul class="nav in" id="side-menu">
<li>
<i class="fa fa-sitemap fa-fw"></i> Multi-Level Dropdown<span class="fa arrow"></span>
<ul class="nav nav-second-level collapse">
<li> Works Correctly!</li>
<li>
Third Level <span class="fa arrow"></span>
<ul class="nav nav-third-level">
<li> DOES NOT WORK - ALWAYS COLLPOASE PARENTS</li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
enter code here
Similar issue and similar solution to the one above, only adding adding class active to all nested <li>. This allows the chevron-right to be a chevron-down.
var url = window.location;
var element = $('ul.nav a').filter(function () {
return this.href == url;
});
if (element) {
element.addClass('active').parents('#side-menu ul').addClass('in');
element.parents('#side-menu li').addClass('active');
}
We recently encountered this problem, a lot of debugging showed, that the problem was with how sb-admin marked html elements as active (specifically, "li" tags).
The file in question is sb-admin-2.js. Down at the bottom it has the following bit of code:
var url = window.location;
var element = $('ul.nav a').filter(function() {
return this.href == url || url.href.indexOf(this.href) == 0;
}).addClass('active').parent().parent().addClass('in').parent();
if (element.is('li')) {
element.addClass('active');
}
First, sb-admin calculates the depth level of your URL and uses this number to index child elements. It then uses this number to iterate through the particular branch of the DOM tree bottom-to-top. It then marks these elements as "active".
In our case the URL wouldn't change, but the number of elements would (for three-levels deep structure it would be 3, but the index remained 2). So, the third and second level elements would become active, but everything else is marked passive, so the top element would collapse, hiding the whole sub-menu.
This is how we fixed it (I'm not a JS guy, so I don't know how good this solution is, but it works):
var url = window.location;
$('ul.nav a').filter(function () {
return this.href == url || url.href.indexOf(this.href) == 0;
}).addClass('active').parents('#side-menu ul').addClass('in');
HTH
var url = window.location;
// var element = $('ul.nav a').filter(function() {
// return this.href == url;
// }).addClass('active').parent().parent().addClass('in').parent();
var element = $('ul.nav a').filter(function() {
return this.href == url;
}).addClass('active').parent();
// while (true) {
// if (element.is('li')) {
// element = element.parent().addClass('in').parent();
// } else {
// break;
// }
// }
This will do the trick guysenter image description here
i have this HTML code for my menu:
<nav id="main-navigation" class="navigation-simple">
<ul>
<li>Home</li>
<li><a class="active-nav" href="">About Us</a>
<ul>
<li><a class="active-nav" href="about">About</a></li>
<li>Testimonials</li>
<li>Meet The Team</li>
</ul>
</li>
</nav>
i have added in the active-nav class but how can i automatically set the active class on parent and child items when the current URL is the href value of the link?
you need java script for this, jQuery is great for beginners!
It could be done like this:
var url = window.location.href;
$( "nav li a" ).each(function(index) {
if (url.indexOf($(this).attr('href')) >= 0){
$(this).addClass('active-nav');
}
});
line by line -
get the current page url
for each link in the navigation...
check if its href is in the current url
if it is, add the class 'active-nav'
close if statement
close for loop
You can use the .filter() method to find the appropriate link and add the required class:
$('#main-navigation li > a').removeClass('active-nav')
.filter(function() {
return location.href.indexOf(this.href) > -1;
})
.addClass('active-nav') //add class to matched element(s)
//add class to parent(s) of matched, if any
.each(function() {
$($(this).parents('a'), '#main-navigation').addClass('active-nav');
});
Also remember to close your first ul.
Something like:
$(function() {
$('#main-navigation a').each(function() {
if(this.href.indexOf(window.location.pathname) === 0) {
$(this).addClass('active-nav');
} else {
// case when something was set to active by the server
$(this).removeClass('active-nav');
}
});
});
will do the job.
Make sure you make the if condition safe to your sites deeplinking implementation (e.g. GET params, anchors or multiple domains with same pathname are possible within your navigation).
I have the navigation bar as below
<ul>
<li class="selected"><a href=">My Profile</a></li>
<li>xxxx</li>
<li>mybook</li>
<li>Photos <span>4</span></li>
<li>Profile List</li>
</ul>
I want that if the url is www.abc.com/user/profile then profile tab class should have class selected attached
If photos then photo tab.
If we can have partial match that will be good but i am not sure if thats possible
like in url i have /user/book and myBook gets selected
Some elegant variant:
<ul class="menu">
<li><a class="profile" href="/user/profile">My Profile</a></li>
<li><a class="book" href="/user/book">My Book</a></li>
</ul>
$(document).ready(function () {
var page = document.location.href.split('/').slice(-1)[0];
$('.menu .' + page).addClass('selected');
});
You can grab the part you want with regex:
var userPage = /user\/(.+)/.exec(location.href)[1];
That will give you the part after user/. Then you could use a switch statement:
switch (userPage) {
case 'profile':
...
break;
case 'book':
...
break;
}
You would want to switch off of location.pathname. Granted that you give that <ul> a class of nav:
$(function () {
if (location.pathname.search("/user/profile") != -1) {
// page is /user/profile
$("#nav li").eq(0).addClass("selected");
} else if (location.pathname.search("/user/photos") != -1) {
// page is some/thing
$("#nav li").eq(3).addClass("selected");
}
... etc
});
Things to notice
We use $(function () {...}); as opposed to $(document).ready(function() {...});. It is less typing and more efficient
We use String.search(), which returns the index at which the string "/user/profile" appears. If the string is not found, String.search() will return -1, so if it != -1, it exists.
We also use jQuery.eq( index ) this treats elements selected by a jQuery selector as an array and returns the element of the specified index.

My DOM looks something like this:
<li>
<li><a class="editEntity>Edit</a></li>
<li><a class="deleteEntity>Delete</a></li>
</li>
When the used clicks on 'Edit', I want to change the outer <li> to <li class="selected>.
I tried something like this, but this is not working:
$('li a.editEntity').live('click', function() {
$(this).closest('li').closest('li').addClass('selected');
});
Any help is appreciated.
Go up a parent:
$(this).closest('li').parent().closest('li').addClass('selected');
It wasn't working because closest starts with the current element, and so if you call it on something that matches the selector, you get back the same thing you started with.
Live example
Or you can use parents with the :eq selector:
$(this).parents("li:eq(1)").toggleClass("selected");
Note that :eq uses 0-based indexes, so :eq(1) is the second parent li.
Live example
Your quoted HTML is invalid, though (an li can't directly contain an li); I assume you meant:
<li>
<ul>
<li><a class="editEntity>Edit</a></li>
<li><a class="deleteEntity>Delete</a></li>
</ul>
</li>
...or similar.
you can use
$('li a.editEntity').live('click', function() {
$(this).parents('li').addClass('selected');
});
following my previous comment.. here's the example promised... :)
$('li').each(function(index) {
alert(index + ': ' + $(this).text());
});
Stop at the second index

I'm using this code to add active class depending on the page. This is working 100% for multi level sub-menus of AdminLTE 3, just put this code in the footer section of your page.
var url = window.location;
const allLinks = document.querySelectorAll('.nav-item a');
const currentLink = [...allLinks].filter(e => {
return e.href == url;
});
currentLink[0].classList.add("active");
currentLink[0].closest(".nav-treeview").style.display = "block ";
currentLink[0].closest("ul.nav-treeview").closest('li').classList.add('menu-open');
$('.menu-open').find('a').each(function() {
if (!$(this).parents().hasClass('active')) {
$(this).parents().addClass("active");
$(this).addClass("active");
}
});
