$(function() {

$.ms_DatePicker({

YearSelector: ".sel_year",

MonthSelector: ".sel_month",

DaySelector: ".sel_day"

});

$.ms_DatePicker();

});

birthday.js内容：(来自github)

(function($){

$.extend({

ms_DatePicker: function (options) {

var defaults = {

YearSelector: "#sel_year",

MonthSelector: "#sel_month",

DaySelector: "#sel_day",

FirstText: "--",

FirstValue: 0

};

var opts = $.extend({}, defaults, options);

var $YearSelector = $(opts.YearSelector);

var $MonthSelector = $(opts.MonthSelector);

var $DaySelector = $(opts.DaySelector);

var FirstText = opts.FirstText;

var FirstValue = opts.FirstValue;

// 初始化

var str = "" + FirstText + "";

$YearSelector.html(str);

$MonthSelector.html(str);

$DaySelector.html(str);

// 年份列表

var yearNow = new Date().getFullYear();

var yearSel = $YearSelector.attr("rel");

for (var i = yearNow; i >= 1900; i--) {

var sed = yearSel==i?"selected":"";

var yearStr = "" + i + "";

$YearSelector.append(yearStr);

}

// 月份列表

var monthSel = $MonthSelector.attr("rel");

for (var i = 1; i <= 12; i++) {

var sed = monthSel==i?"selected":"";

var monthStr = "" + i + "";

$MonthSelector.append(monthStr);

}

// 日列表(仅当选择了年月)

function BuildDay() {

if ($YearSelector.val() == 0 || $MonthSelector.val() == 0) {

// 未选择年份或者月份

$DaySelector.html(str);

} else {

$DaySelector.html(str);

var year = parseInt($YearSelector.val());

var month = parseInt($MonthSelector.val());

var dayCount = 0;

switch (month) {

case 1:

case 3:

case 5:

case 7:

case 8:

case 10:

case 12:

dayCount = 31;

break;

case 4:

case 6:

case 9:

case 11:

dayCount = 30;

break;

case 2:

dayCount = 28;

if ((year % 4 == 0) && (year % 100 != 0) || (year % 400 == 0)) {

dayCount = 29;

}

break;

default:

break;

}

var daySel = $DaySelector.attr("rel");

for (var i = 1; i <= dayCount; i++) {

var sed = daySel==i?"selected":"";

var dayStr = "" + i + "";

$DaySelector.append(dayStr);

}

}

}

$MonthSelector.change(function () {

BuildDay();

});

$YearSelector.change(function () {

BuildDay();

});

if($DaySelector.attr("rel")!=""){

BuildDay();

}

} // End ms_DatePicker

});

})(jQuery);

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;

}
