如何使用<html:select> 标签
注意: 一定要先写好 action 和 actionFrom
这是测试actionForm.
package test;
import org.apache.struts.action.*;
import javax.servlet.http.*;
public class test extends ActionForm
{
private String value="2"; 值为2. 将在select中自动选中该项.只做测试用.
public String getValue()
{
return value;
}
public void setValue(String value)
{
this.value = value;
}
public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest
httpServletRequest)
{
/**@todo: finish this method, this is just the skeleton.*/
return null;
}
public void reset(ActionMapping actionMapping, HttpServletRequest
httpServletRequest)
{
}
}
以下是一个action
package test;
import org.apache.struts.action.*;
import javax.servlet.http.*;
public class testAction extends Action
{
public ActionForward execute(ActionMapping actionMapping, ActionForm actionForm,
HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse)
throws Exception
{
return null;
}
}
以下是一个JSP文件的示例.
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ page contentType="text/html; charset=iso-8859-1" %>
<html:html>
<head>
<title>
te.jsp
</title>
</head>
<body>
<h1>JBuilder Generated Struts JSP for ActionForm test.test</h1>
<!--
以下是一个创建一个ArrayList. 也可在DB中获取数据.
这里只是一个演示.
在程序中可以用 request 进行对象传送...
-->
<%
java.util.Collection list = new java.util.ArrayList();
for(int i=0;i<5;i++)
{
java.util.HashMap li = new java.util.HashMap();
li.put("id",i+""); file://这里存放select选项的值.
li.put("name","name"+i); file://这里存放select选项名称.
list.add(li);
}
pageContext.setAttribute("myList", list);
%>
<p>
<html:form action="/testAction.do" method="POST">
<html:text property="value"/>
<br>
<html:select property="value">
<html:options collection="myList" property="id" labelProperty="name"/>
</html:select>
<br>
<html:submit property="submit" value="Submit"/><br>
<html:reset value ="Reset"/>
</html:form>
</body>
</html:html>
最后请在你的struts_config.xml 中加入你的 bean和action
