怎么得到选择的值？
function getBirthday() { var date = ""; date += $(".sel_year").val(); date += "-"; if (parseInt($(".sel_month").val()) < 10) { date += "0"; date += $(".sel_month").val(); } else { date += $(".sel_month").val(); } date += "-"; if (parseInt($(".sel_day").val()) < 10) { date += "0"; date += $(".sel_day").val(); } else { date += $(".sel_day").val(); } return date; }
