I achived this by doing the following, but as a newbie to javascript and jquery i want to know if there is any shorter way to add multiple possible values.
if ($("input:first").val().toUpperCase() == "UNITED STATES" || $("input:first").val().toUpperCase() == "USA" || $("input:first").val().toUpperCase() == "AMERICA") {
$("#check").text("Correct!").show().fadeOut(5000);
return true;
Like
if ($("input:first").val().toUpperCase() == ("UNITED STATES","USA","AMERICA")) {
$("#check").text("Correct!").show().fadeOut(5000);
return true;
by this only validates the last answers in this case AMERICA.
Using $.inArray():
