Answer 2

Change to this

(var i = 0, len = elem.length; i < len; i++)

from this:

(var i = 0, len = sels.length; i < len; i++)

Answer 3

change your select box to have as value the position of message in your array for example when it shows A, then in change event you can get the message

$('Yourselect').change(function(){
var msg = YourArray[$(this).val()];
// Show it wherever yu want
});
