Hover an I tag change the font icon inside it and before it

Question

I have this code:

<div class="rate-instructors">
  <i class="fa fa-star"></i>
  <i class="fa fa-star"></i>
  <i class="fa fa-star"></i>
  <i class="fa fa-star"></i>
  <i class="fa fa-star"></i>
</div>

<div class="rate-activities">
  <i class="fa fa-star"></i>
  <i class="fa fa-star"></i>
  <i class="fa fa-star"></i>
  <i class="fa fa-star"></i>
  <i class="fa fa-star"></i>
</div>

I wanted to change it to fa fa-star-o , for example I hovered the 3rd i in rate-instructors, I wanted it and the first 2 to be in fa fa-star-o only in div with class rate-instructors . Is it possible?

My tried code:

 $('i').each(function() {
    $(this).attr('class','fa fa-star-o');
 });

Answer 1

You can do something like this:

$(".rate-instructors i,.rate-activities i").hover(function(){
  $(this).add($(this).prevAll("i")).removeClass("fa-star").addClass("fa-star-o");
  $(this).nextAll("i").removeClass("fa-star-o").addClass("fa-star");
})

Demo

 $(".rate-instructors i,.rate-activities i").hover(function(){ $(this).add($(this).prevAll("i")).removeClass("fa-star").addClass("fa-star-o"); $(this).nextAll("i").removeClass("fa-star-o").addClass("fa-star"); })
