struts 2.x版本 datetimepicker日期控件的使用

In Struts 2, the dojo ajax tag “<sx:datetimepicker>” will render a text box and append a calender icon behind, click on the calender icon will prompt a date time picker component.

To create a date time pick component, just ensure :
1. Download the struts2-dojo-plugin.jar library.
2. Include the “struts-dojo-tags” tag and output its header.

开始时把struts2-dojo-plugin.jar包导入到项目WEB-INF/libx下

<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
<html>
<head>
<sx:head />
</head>

For example,

<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
<html>
<head>
<sx:head />
</head>
<body>
<sx:datetimepicker name="date2" label="Format (dd-MMM-yyyy)"
displayFormat="dd-MMM-yyyy" value="%{'2010-01-01'}"/>
...

Resulting the following HTML, few dojo and JavaScript libraries to create a date time pick component.

<html>
<head>
<script language="JavaScript" type="text/javascript"> // Dojo configurationdjConfig = {isDebug: false,bindEncoding: "UTF-8",baseRelativePath: "/Struts2Example/struts/dojo/",baseScriptUri: "/Struts2Example/struts/dojo/",parseWidgets : false};
</script>

</head>
...
<td class="tdLabel">
<label for="widget_1291193434" class="label">Format (dd-MMM-yyyy):
</label></td>
<td>
<div dojoType="struts:StrutsDatePicker"    id="widget_1291193434"
value="2010-01-01"    name="date2"    inputName="dojo.date2"
displayFormat="dd-MMM-yyyy"  saveFormat="rfc"></div>
</td>
</tr>
<script language="JavaScript" type="text/javascript">
djConfig.searchIds.push("widget_1291193434");</script>

Struts 2 <S:datetimepicker> Example

A complete full example of the <s:datetimepicker> tag to generate a datetimepicker component, and show the use of OGNL and Java property to set the default date to the “datetimepicker” component.

1. Pom.Xml

Download the Struts 2 dojo dependency libraries.

pom.xml

//...<!-- Struts 2 --><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-core</artifactId><version>2.1.8</version></dependency><!-- Struts 2 Dojo Ajax Tags --><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-dojo-plugin</artifactId><version>2.1.8</version></dependency>
//...

2. Action Class

Action class to store the selected date.

DateTimePickerAction.java

package com.mkyong.common.action;import java.util.Date;
import com.opensymphony.xwork2.ActionSupport;public class DateTimePickerAction extends ActionSupport{private Date date1;private Date date2;private Date date3;//return today datepublic Date getTodayDate(){return new Date();}//getter and setter methodspublic String execute() throws Exception{return SUCCESS;}public String display() {return NONE;}}

3. Result Page

Render the date time picker component via “<s:datetimepicker>” tag, set the default date via Java property and OGNL.

The ‘displayFormat‘ attribute is supported in many date patterns, read this article – Date Format Patterns.

Ensure you put the “struts-dojo-tags” tag and render it’s header <sx:head />

<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
<html>
<head>
<sx:head />
</head>

datetimepicker.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
<html>
<head>
<sx:head />
</head><body>
<h1>Struts 2 datetimepicker example</h1><s:form action="resultAction" namespace="/" method="POST" ><sx:datetimepicker name="date1" label="Format (dd-MMM-yyyy)"
displayFormat="dd-MMM-yyyy" value="todayDate" /><sx:datetimepicker name="date2" label="Format (dd-MMM-yyyy)"
displayFormat="dd-MMM-yyyy" value="%{'2010-01-01'}"/><sx:datetimepicker name="date3" label="Format (dd-MMM-yyyy)"
displayFormat="dd-MMM-yyyy" value="%{'today'}"/><s:submit value="submit" name="submit" /></s:form></body>
</html>

result.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>
<html><body>
<h1>Struts 2 datetimepicker example</h1><h4>Date1 : <s:property value="date1"/>
</h4> <h4>Date 2 : <s:property value="date2"/>
</h4> <h4>Date 3 : <s:property value="date3"/>
</h4> </body>
</html>
