Use jQuery's addBack()
method:
$(this).parent().siblings().addBack().removeClass("active");
This selects an element's siblings, and itself, so that you can remove the class.
If you're using a jQuery version less than 1.8, use andSelf()
instead.
Update: I've added an example below to show exactly what this method will do.
$('.active a').click(function(){
$(this).parent().siblings().addBack().removeClass("active");
});
.active {background: yellow}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="active">I'm active. <a href="#">Remove all active</a></div>
<div class="active">I'm active. <a href="#">Remove all active</a></div>
<div class="active">I'm active. <a href="#">Remove all active</a></div>
<div class="active">I'm active. <a href="#">Remove all active</a></div>
<div class="active">I'm active. <a href="#">Remove all active</a></div>
