How to make a hover effect change another "object" selected in jqGrid?

Question

I have two classes A and B, I need that when you mouse over A what changes is the value, color etc of B.
I don’t know if I can do this in CSS or using Onmouseover.

Answer 1

Come on I’ll give you an example

<style>
    .azul{color: blue;}
</style>

<script>
    $('#a').hover(function(){
        $('#b').toggleClass('azul'); // muda a cor do texto em B quando A estiver hover
        $('#b').text('novoValor'); // muda o valor de B quando A estiver hover
    });
</script>
