1.使用c标签前的准备
为了完全在JSP中消除Java代码,学习JAVA的标签库:
Java标签库:
标准标签库(JSTL).(SUN预先提供好的,我们使用的.)
以后学习MVC框架(Struts2/SpringMVC)的时候,都会学习一套标签.
=====================================================================
准备:
1:准备JSTL相关的jar(Tomcat根/webapps/examples/WEB-INF/lib).
jstl.jar standard.jar
el-api.jar jsp-api.jar
2:使用JSTL的JSP页面中,引人标签库:
比如引人核心JSTL:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
3:注意:有的idea没有添加c标签库,所以必须手动添加
2.ide配置
jsp代码:
1 <%@ page contentType="text/html;charset=UTF-8" language="java" pageEncoding="UTF-8" %> 2 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> 3 <html> 4 <head> 5 ????<title>车票列表</title> 6 </head> 7 <body> 8 我是车票列表页面 9 10 <%--11 表格标签12 行 ??<tr>13 列 ???<td>14 --%>15 <table align="center" border="1">16 ????<tr>17 ????????<td>编号</td>18 ????????<td>start_station</td>19 ????????<td>stop_station</td>20 ????????<td>start_time</td>21 ????????<td>ticket_price</td>22 ????</tr>23 ???<c:forEach items="${list}" var="ticket">24 ??????<tr>25 ??????????<td>${ticket.id}</td>26 ??????????<td>${ticket.startStation}</td>27 ??????????<td>${ticket.stopStation}</td>28 ??????????<td>${ticket.startTime}</td>29 ??????????<td>${ticket.ticketPrice}</td>30 ??????</tr>31 ???</c:forEach>32 33 </table>34 </body>35 </html>
