Struts2中的datetimepicker是一个时间选择器，个人觉得是一个非常方便的标签，我们知道用JavaScript代码实现一个日期选择器那要写好长以段代码，而Struts2内置的这个datetimepicker标签却帮我们摆脱了长长的JavaScript的噩梦。来看一下就知道了：
datetimepicker.jsp：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<s:head theme="simple"/>
<!-- 上面这个head标签必须要加，至于设置哪种主题没有限制，根据自己开发的需要 -->
<!-- 当没有加的时候就没有显示，这是为什么？我学习的时候不懂，谁看到了帮我解释下 -->
<body>
<s:datetimepicker value="today" name="getdate" label="时间选择器"></s:datetimepicker>
</body>
</html>
可以看到很漂亮的效果：
当然我们可以格式化日期格式，一些其他的处理可以根据需要在action里面进行处理。来看一个初始化时间为2008-08-08，按照年月日显示的日期选择器：
增加下列代码到上面的JSP里面：
<s:datetimepicker name="hopedate" label="year-month-date" displayFormat="yyyy-MM-dd" />增加一个DatetimepickerAction.java:
package com.kalman03.action;
import java.util.Date;
import com.opensymphony.xwork2.ActionSupport;
/**
*@FileName DatetimepickerAction.java
*
*@Author kalman03
*
*/
public class DatetimepickerAction extends ActionSupport {
private Date hopedate;
public Date getHopedate() {
return hopedate;
}
public void setHopedate(Date hopedate) {
this.hopedate = hopedate;
}
@Override
public String execute() throws Exception {
this.setHopedate(new Date("Aug 08,2008 12:00:00 AM"));
return SUCCESS;
}
}
配置struts.xml里面的映射关系：
<action name="datetimepickertag" class="com.kalman03.action.DatetimepickerAction">
<result>/datetimepicker.jsp</result>
</action>到此结束可以在浏览器输入：http://localhost:8080/test/datetimepickertag.action得到格式化后的效果：
我对Struts2的这个标签无语，太强了，有时间好好看看内部是怎么处理的。在这个我再提供给大家一个JavaScript实现的日期选择器，需要声明的是这个JavaScript摘自 kimsoft-jscalendar
js源码（支持IE，Firefox,Safari，Opera，谷歌等多浏览器）：
