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 configuration djConfig = { isDebug: false, bindEncoding: "UTF-8" ,baseRelativePath: "/Struts2Example/struts/dojo/" ,baseScriptUri: "/Struts2Example/struts/dojo/" ,parseWidgets : false }; </script> <script language="JavaScript" type="text/javascript" src="/Struts2Example/struts/dojo/struts_dojo.js"></script> <script language="JavaScript" type="text/javascript" src="/Struts2Example/struts/ajax/dojoRequire.js"></script> <link rel="stylesheet" href="/Struts2Example/struts/xhtml/styles.css" type="text/css"/> <script language="JavaScript" src="/Struts2Example/struts/utils.js" type="text/javascript"></script> <script language="JavaScript" src="/Struts2Example/struts/xhtml/validation.js" type="text/javascript"></script> <script language="JavaScript" src="/Struts2Example/struts/css_xhtml/validation.js" type="text/javascript"></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>

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

<%@ 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>
