I want to add a hidden
class to all li
but not to the li
which was clicked. How can I do this using jQuery?
<ul class="render-menu">
<li class="font-size">list 1</li>
<li class="font-size">list 2</li>
<li class="font-size">list 3</li>
<li class="font-size">list 4</li>
</ul>
jQuery(".render_menu li").on('click', function() {
alert();
jQuery(".render_menu").not($(this)).parent().addClass('hidden');
});
Firstly note that your class
in the HTML is render-menu
, yet the JS was using render_menu
. You need to make them consistent.
With regard to the issue, you're adding the class to the parent()
of the li
, ie. the ul
, so all the child elements are being affected by the class. To fix this, use siblings()
to get all the li
elements you require before calling addClass()
. Try this:
$(".render-menu li").on('click', function() { $(this).siblings().addClass('hidden'); });
.hidden { display: none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <ul class="render-menu"> <li class="font-size">list 1</li> <li class="font-size">list 2</li> <li class="font-size">list 3</li> <li class="font-size">list 4</li> </ul>
Change your JS code to below
jQuery(".render_menu li").on('click', function () {
alert();
jQuery(".render_menu li").not($(this)).addClass('hidden');
});
You are comparing ul
instead of li
to add class
You can try the following
$('.render-menu li').on('click',function(){ $('.render-menu li').removeClass('hidden').not(this).addClass('hidden'); });
.hidden{ color:lightgray; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <ul class="render-menu"> <li class="font-size">list 1</li> <li class="font-size">list 2</li> <li class="font-size">list 3</li> <li class="font-size">list 4</li> </ul>
