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>
