jstl el表达式c:forEach标签迭代

一直用struts2标签,el表达式都忘的差不多了。

做了个简单的例子。

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%
	List list = new ArrayList();
	for (int i = 0; i < 10; i++) {
		list.add(i);
	}
	session.setAttribute("list", list);
%>

<html>
  <head>
    
    <title>My JSP 'index.jsp' starting page</title>
	<meta http-equiv="pragma" content="no-cache">

	tr.foreach_tr2{background-color:#A7DBFF; color:black ;}
	</style>
  </head>
  
  <body>
	<table border="1" width="200" cellpadding="0" cellspacing="0">
		<tr align="center"  class="first_tr">
			<td>
				test
			</td>
		</tr>
		<c:forEach items="${list}" varStatus="i" var="item" >
			<c:if test="${i.index % 2 == 0}" >
				<tr align="center" class="foreach_tr1">
			</c:if>
			<c:if test="${i.index % 2 == 1}">
				<tr align="center" class="foreach_tr2">
			</c:if>
			<td>
				<h2>${item}</h2>
			</td>
		</tr>
		</c:forEach>
	</table>
  </body>
</html>
