抽象出JSCalendar，可直接使用，非常簡單

1.引入JSCalendar

<!--導入calendar -->
<script type="text/javascript" src="styles/calendar/calendar.js"></script>
<script type="text/javascript" src="styles/calendar/calendar-setup.js"></script>
<script type="text/javascript" src="styles/calendar/lang/calendar-en.js"></script>
<link href="styles/calendar/calendar-win2k-cold-1.css" type="text/css" rel="stylesheet"/>

2.直接使用

<input type="text" id="cal-field-1" name="duedate" value=""/>   
          			<button type="button" id="cal-button-1">...</button>
          						<script type="text/javascript">
          						Calendar.setup({
          						inputField    : "cal-field-1",
          						ifFormat    : "%Y-%m-%d", 
          						button        : "cal-button-1"});
          						</script>

注意：
inputField  : "publisherDate",      // id of the input field
ifFormat    : "%Y-%m-%d",       // the date format
button      : "publisherDateBt"    // id of the button
