$("." + somevar).show()

I think it should be as simple as

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

$("." + somevar).show();

$(document).ready(function(){

  var somevar = ".apple"

      $(somevar).show();

});

That will show .apple

$(document).ready(function(){

  var somevar = "apple"

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

});

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