用来输入出生日期的好用JavaScript
个人感觉非常好用的一个日期选择器
Code
1<script type="text/javascript">

var $ = function (id) {
3
return "string" == typeof id ? document.getElementById(id) : id;

7 if (oTarget.addEventListener) {
8 oTarget.addEventListener(sEventType, fnHandler, false);

10 oTarget.attachEvent("on" + sEventType, fnHandler);

12 oTarget["on" + sEventType] = fnHandler;
