So far my coding is working only adding the class when mouseenter but never remove the active class when mouseenter other element.

What I have tried:

Check out my coding below :

JavaScript

$(document).ready(function() {
  $("#1, #2, #3").mouseenter(function() {
	$(this).removeClass("active")
	$("#" + this.id).addClass("active");
  });
});

.active {
		background: #fff;
	}

HTML

<pre><ul>
  <li><a class="active" id="1">number 1</a></li>
  <li><a id="2">number 2</a></li>
  <li><a id="3">number 3</a></li>
</ul>

Solution 1

Update the script to remove class form all elements before adding

JavaScript

$(document).ready(function() {

  $("#1, #2, #3").mouseenter(function() {
    $("#1, #2, #3").removeClass();
    $("#" + this.id).addClass("active");
  });
  
});

Thank you for your reply but this isn't what I need. I wanted to make the class stay active even after mouseleave until mouseenter to other element then only the class active switch. How to do that?

Odd :) anyway, then you are close, I think this should do the trick

$("#1, #2, #3").mouseenter(function() {
$("#1, #2, #3").removeClass();
$("#" + this.id).addClass("active");
});
