JSP CSS JavaScript HTML

如某一jsp页面要引入一个时间控件，该文件名为test.jsp，源码如下：
----------------------------------------------------
<%@ page language="java" contentType="text/html; charset=gbk" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

"http://www.w3.org/TR/html4/loose.dtd">
<html>

<jsp:include page="./calendar/cal.jsp"></jsp:include>------------------------（1）

<input type="text" name="startdate_str" value="" readonly="readonly"><img

src="./images/datetime.gif" style="cursor:hand;" alt="弹出日历选择框"
onclick="return showCalendar('startdate_str', '%Y-%m-%d %H:%M:%S', '24',

true);">------------------------------------------------------（2）

</td>
</tr>

</table>
</html>
-----------------

说明：
1.其中（1）（2）标签为必须；
2.showCalendar('startdate_str', '%Y-%m-%d %H:%M:%S', '24', true)方法的参数说明其中 "startdate_str" 需要和 name="startdate_str"一致，且名称中不能有“.”； '%Y-%m-%d %H:%M:%S'表示要显示的时间格式；“24”表示时间的12/24小时制。

cal.jsp文件如下：
-----------------------------------
<%
String calPath=request.getContextPath()+"/etc/calendar";
%>
<link rel="alternate stylesheet" type="text/css" media="all" href="<%=calPath%>/calendar-

blue.css" title="winter" />
<link rel="alternate stylesheet" type="text/css" media="all" href="<%=calPath%>/calendar-

<link rel="alternate stylesheet" type="text/css" media="all" href="<%=calPath%>/calendar-

<link rel="alternate stylesheet" type="text/css" media="all" href="<%=calPath%>/calendar-

<link rel="stylesheet" type="text/css" media="all" href="<%=calPath%>/calendar-win2k-1.css"

    cal.callCloseHandler();
}

// And this gets called when the end-user clicks on the _selected_ date,
// or clicks on the "Close" button. It just hides the calendar without
// destroying it.

if (calendar != null) {
    // we already have some calendar created

// as 4 digit number, date.getMonth() -- returns the month as 0..11,
// and date.getDate() -- returns the date of the month as 1..31, to
// make heavy calculations here. However, beware that this function
// should be very fast, as it is called for each day in a month when
// the calendar is (re)constructed.
function isDisabled(date) {
var today = new Date();
return (Math.abs(date.getTime() - today.getTime()) / DAY) > 10;
}

// construct a calendar giving only the "selected" handler.

// hide week numbers
cal.weekNumbers = false;

// We want some dates to be disabled; see function isDisabled above
cal.setDisabledHandler(isDisabled);

// this call must be the last as it might use data initialized above; if
// we specify a parent, as opposite to the "showCalendar" function above,
