Question

For example, if i had a variable in javascript

 var nombre;
 onclick="nombre='someValue'"

and somewhere along in my code this javascript variable’s value is changed like above, could I set the value of that variable to be the class name in the jquery selector so it would be like

$('.someValue').show()

Answer 1

Yes you can:

$('.' + nombre).show();

This assumes that your variable nombre has such scope that it is available in your jQuery code too.
