I'm a newbie so i hope my question will have some logic :)
i wish to add a class "active" to "li" (in this case a portfolio filter item in the page) by clicking on a link from the nav menu.
the "li" is not a part of the nav menu, how do i assign a "li" with a class if the "li" is in the deep tree - it's a whole different part of my site.
the "li" is in:
<div class=""section"
<ul id="portfolio-filter" class="list-inline">
<li <--- the place i wish the "active" be added
i have checked other question but couldn't figure out how to implement the specific need.
thanks for the help
You have to create a listener for the link of the menu. In JQuery, to create a listener, you have the 'on' function.
Example :
$("myElement").on("click",function(){});
After that, add an id attribute for the 'li' tag.
For example:
<li id="myLI">
So, when the user will click on the link of the menu, it will go to the listener. And in the listener, you will do :
$("#myLI").addClass("active")
Don't forget to create the css class.
First you have to specify .active in your CSS.
.active {
//add styles here
}
Then using javascript you have to grab #myLI and set class .active to it using onclick event:
var element = document.getElementById("myLI");
element.onclick = function() {
element.setAttribute('class','active');
}

I have a list and that contains sub menus with title anchor tags. And I just need to add class to its title anchor tag if dropdown menu li has an active class. Please take a look at this screenshot.
I easily do this by adding unique class to anchor tag and find that and add class. But what if I have more sub menus with title tag? Then I have to repeat my jQuery script again and again.
So I tried this way doing.
$(document).ready(function () {
if (jQuery(".dropdown li").hasClass("active")) {
$(this).closest("a").addClass("main-link");.
}
});
But it's not working. Is there any way to do this?
Here is the fiddle
.closest() finds the closest containing element that matches the selector. The a is not a container of the dropdown, it's the element before the dropdown. For that you need to use .prev().
You also shouldn't be using if and this. if doesn't bind this to the elements where the condition succeeds. Just use a selector and DOM navigation from that.
$(document).ready(function() {
$(".dropdown:contains(li.active)").prev("a").addClass("main-link");
});
Closest looks at parents, the anchor is not a parent. Plenty of ways to walk the tree
$("li.active").parent().closest("li").find(">a").addClass("foo");
$("li:has(> ul > li.active)").find(">a").addClass("bar");
.foo { background-color: yellow; }
.bar { color: red; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
<li>
<a>A</a>
<ul>
<li class="active">X</li>
</ul>
</li>
</ul>
$("li.active").parent().closest("li").find(">a").parent().addClass("active");
If child has an active class, add class to before anchor tag of parent
I'm a little stuck here. I have a ul menu of links. When a user selects from this list, I'm calling up content from another page with ajax. I want to grab a data attribute (data-flag) from the selected anchor and add that attribute as a class to the div that holds the ajax content (#fourteen). The adding class piece is working fine. However, when a new item is selected from the ul menu, I can't seem to remove the other classes from the content div. With each click, it just adds more classes.
Here's my code.
<ul id="langtest" class="tp_lang2">
<li>English</li>
<li>中文(简体)</li>
<li>Nederlands</li>
<li>Français</li>
</ul>
<div id="fourteen" class="cn">
<div id="content">
<div class="main-content">Content being served up here.
</div>
</div>
</div>
<script>
jQuery("ul#langtest li a").click(function() {
jQuery('#fourteen').load($(this).attr("href") + " #content");
jQuery('#fourteen').removeClass.not(this).attr("data-flag");
jQuery('#fourteen').addClass($(this).attr("data-flag"));
return false;
});
</script>
You just need to remove all class in the element like so :
// remove all class
jQuery('#fourteen').removeClass();
// then add class name with data flag selected anchor only
jQuery('#fourteen').addClass($(this).attr("data-flag"));
DEMO(inspect element to see the class actually added & removed)
Your removeClass seems not perfect. Do it like below.
jQuery('#fourteen').removeClass();
On dynamically added element you have to use delegate event binding.
jQuery(document).on("click","ul#langtest li a",function() {
jQuery('#fourteen').load($(this).attr("href") + " #content");
//also change your removeClass code
jQuery('#fourteen').removeClass();
jQuery('#fourteen').addClass($(this).attr("data-flag"));
return false;
});
I have 5 a link items in a row, encapsulated within a h4 and the h4 within li element and the li within ul which it's finally nested in a nav element.
At the moment, the role of a (thanks to a very helpful example that I found here) when clicked is to change the content of the divs (that contain images and text).
What I would like to do in addition, is that when you click the link and the content changes, I would like a link to receive the "active" class, which has white color and certain other css attributes.
<script>
$(function() {
$( "#tabs" ).tabs();
});
</script>
the function that swaps the content
<nav id="nav2">
<ul class="tabz">
<li><h4>Szenario 1</h4></li>
<li><h4>Szenario 2</h4></li>
<li><h4>Szenario 3</h4></li>
<li><h4>Szenario 4</h4></li>
<li><h4>Szenario 5</h4></li>
</ul>
</nav>
When the page loads, everything displays correctly. When I click the second link I would like the "active" class to be removed from first link and go to the sencond.
(The css of the active class is just some color and border differences.)
Thank you very much in advance.
Attach handler for those anchor tags by using the attribute starts with selector, since you are having href with same beginning. And by using the $(this) reference set the active class and remove the active class from all of its anchor siblings.
Try,
$('[href^="#tabs"]').click(function(){
$(this).addClass('active');
$(this).closest('.tabz').find('a').not($(this)).removeClass('active');
});
$('[href^="#tabs"]').click(function(e){
$(this).addClass('active').parents('li').siblings().find('a').removeClass('active');
});
With the markup you have, the clicked a element won't have any sibling, but its li parent will, so this code will work as expected, see here : DEMO
I have a drop down menu that returns results after a selection. The user can then click a link, cloning the dropdown menu, and choose another selection that will return more results. The structure of the results div is as follows:
<ul>
<li class="red">
<span> some html content</span>
</li>
<li class="red">
<span> some html content</span>
</li>
</ul>
I would like the user to click an li and change the background color. The user should only be able to change the color of one li at a time. I am able to accomplish this first part using:
$("li.red, li.blue").live("click",function() {
var $this, c;
$this = $(this);
c = $this.hasClass("red")
? {us: "blue", them: "red" }
: {us: "red", them: "blue" };
$("li." + c.us).removeClass(c.us).addClass(c.them);
$this.removeClass(c.them).addClass(c.us);
});
The problem is that when the user adds another selection (and the previous dropdown is cloned using jquery), and clicks an li in that results div, the previous selection is unselected. I want the user to be able to change the background of the li for the first set of results, as well as change the background for the second set of results. So each set of results would be able to toggle background colors between only that particular ul.
Any help is much appreciated!
Try this...
$("ul").on("click", "li", function() {
$(this).parent().find("li").removeClass("red").addClass("blue");
$(this).toggleClass("red").toggleClass("blue");
});

Giving the ul a class name or ID would make sure it only affects the list in question. It looks a little pointless, but I used parent and find so that you only have to change the ul selector if you do give it a class or ID, and it will still work.
Try to use on() instead of live():
$(document).on("click","li.red, li.blue",function() {
...
});
I have a list in which I am dynamically adding the classname, now when I click on that item again the class stays there. I dont want that I want that classname to be assigned to the currently clicked list item.
<ul id="menubar">
<li>one</li>
<li>two</li>
</ul>
Now when I click on one I dynamically add classname, and when I click on two the classname stays the same on one and it gets affected on two as well. but I want it to be removed from one and to be applied to currently clicked item.
How can I achieve it?
$$('#menubar li').invoke('observe', 'click', (function(e) {
//removes classname from all the li elements
$$('#menubar li').invoke('removeClassName', 'myClass');
//Gets the li you clicked on
var list_item = Event.element(e);
//adds the classname
list_item.addClassName('myClass');
}).bindAsEventListener(this));
You need to be including .removeClass() in the same event as when you addClass() to the other one.
$('.one').click(function(){
$(this).addClass('myClass');
$('.two').removeClass('myClass');
});
This could be written more efficiently, but im writing this in between meetings.
Hope it's a start!
