JSTL核心标签库使用

JSTL是什么？

java standard taglib(java标准标签库)。

标签是什么？

sun公司制订的一种技术规范，用来将jsp页面中的java代码使用类似于html当中的标记来替换的一种技术。这样做的目的，是为了使jsp页面更好维护以及更好的测试。

JSTL 核心标签库标签共有13个，功能上分为4类：

1.表达式控制标签：out、set、remove、catch

2.流程控制标签：if、choose、when、otherwise

3.循环标签：forEach、forTokens

4.URL操作标签：import、url、redirect

使用标签时，一定要在jsp文件头加入以下代码：

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

下面分别对这些标签进行说明：

表达式控制标签：

1. <c:out> 用来显示数据对象（字符串、表达式）的内容或结果

使用Java脚本的方式为：<% out.println("hello") %> <% =表达式 %>

使用JSTL标签：<c:out value="" default="" escapeXml="">，

　　value属性:用于输出指定的值比如:value="${name}"

　　default属性：指定默认的值比如：default="卡当"

　　escapeXml属性：设置成true，会将value中的特殊字符替换成相应的实体。缺省值就是true。 escapeXml="true"

例如：后台return了一个user对象，并且nickName为user的属性值为"kadang"

 　　　　<c:out value="${user.nickName}欢迎您登录"></c:out>

        <c:out value="&lt要显示的数据对象（未使用转义字符）&gt" escapeXml="true" default="默认值"></c:out><br/>

        <c:out value="&lt要显示的数据对象（使用转义字符）&gt" escapeXml="false" default="默认值"></c:out><br/>

        <c:out value="${null}" escapeXml="false">使用的表达式结果为null，则输出该默认值</c:out><br/>

网页的显示效果为:

2. <c:set var="" scope="" value=""> 用于将变量存取于 JSP 范围中或 JavaBean 属性中。绑订一个对象到指定的范围。

var属性：指定一个绑订名

scope属性：指定范围

value:绑定值

下面的例子中假设已经有 Person.java 这个类文件。

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>

<%@page contentType="text/html; charset=utf-8" %>

<jsp:useBean id="person" class="kadang.Person"></jsp:useBean>

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <title>JSTL测试</title>

  </head>

  <body>

  <c:set value="张三" var="name1" scope="session"></c:set>

  <c:set var="name2" scope="session">李四</c:set>

  <c:set value="赵五" target="${person}" property="name"></c:set>

  <c:set target="${person}" property="age">19</c:set>

  <li>从session中得到的值：${sessionScope.name1}</li>

  <li>从session中得到的值：${sessionScope.name2}</li>

  <li>从Bean中获取对象person的name值：<c:out value="${person.name}"></c:out></li>

  <li>从Bean中获取对象person的age值：<c:out value="${person.age}"></c:out></li>

  </body>

</html>

一共有四种语法格式，前两种是给jsp的范围变量赋值，后两个是给 javabean 变量赋值

效果如下：

3.<c:remove> 主要用来从指定的 jsp 范围内移除指定的变量。使用类似，下面只给出语法：

<c:remove var="变量名" [scope="page|request|session|application"]></c:remove>

4.<c:catch> 用来处理 JSP 页面中产生的异常，并存储异常信息

<c:catch var="name1">

      容易产生异常的代码

</c:catch>

如果抛异常，则异常信息保存在变量 name1 中。

流程控制标签:

1.<c:if>

<c:if test="条件1" var="name" [scope="page|request|session|application"]></c:remove>

test属性:当值为true，执行标签体的内容，为false，则不执行。

var属性：指定一个绑订名。

scope属性：指定一个绑定范围。

var属性和scope属性用于将test的结果绑订到指定的对象

假设后台return了一个user对象，并且nickName为user的属性值为"kadang"

<body>

     <c:if test="${user.nickName=='kadang'}"  var="name1">

         您是卡当的会员

     </c:if>

      <c:if test="${user.nickName=='taobao'}"  var="name2">

         您是淘宝的会员

     </c:if>

     <c:out value="${name1}"></c:out>

     <c:out value="${name2}"></c:out>

  </body>

浏览器显示：

2. <c:choose> <c:when> <c:otherwise> 三个标签通常嵌套使用，第一个标签在最外层，最后一个标签在嵌套中只能使用一次

<c:choose>
用于分支，当某个条件满足，执行某一个分支。每一个分支条件用when标签来表示。

<c:when test=""> 可出现多次，只用于<c:choose>
test属性：当值为true，执行标签体的内容
<c:otherwise> 只出现1次，只用于<c:choose> 当其它分支都不满足条件，则执行该标签体的内容。

例：

<body>

        <c:set var="score">85</c:set>

        <c:choose>

            <c:when test="${score>=90}">

                    你的成绩为优秀！

            </c:when>

            <c:when test="${score>=70&&score<90}">

                    您的成绩为良好!

            </c:when>

            <c:when test="${score>60&&score<70}">

                    您的成绩为及格

            </c:when>

            <c:otherwise>

                对不起，您没有通过考试！

             </c:otherwise>

        </c:choose>

    </body>

浏览器显示：

循环标签:

1.<c:forEach>语法：<c:forEach var="name" items="Collection" varStatus="statusName" begin="begin" end="end" step="step"></c:forEach>

该标签根据循环条件遍历集合 Collection 中的元素。 var 用于存储从集合中取出的元素；items 指定要遍历的集合；varStatus 用于存放集合中元素的信息。

用于遍历集合items属性：指定要遍历的集合。
var属性：指定一个绑订名，jsp引擎会从集合当中取一个对象，绑订到 pageContext对象上。
varStatus属性：指定一个绑订名，对应的绑订值是一个java对象，封装了遍历时的一些信息，包括当前遍历的对象的下标(index)以及是第几次(count)遍历。

varStatus 一共有4种状态属性，下面例子中说明：

<%@ page contentType="text/html;charset=GBK" %>

<%@page import="java.util.ArrayList"%>

URL操作标签：

1：<c:import> 把其他静态或动态文件包含到 JSP 页面。与<jsp:include>的区别是后者只能包含同一个web应用中的文件，前者可以包含其他web应用中的文件，甚至是网络上的资源。

语法：<c:import url="url" [context="context"] [value="value"] [scope="..."] [charEncoding="encoding"]></c:import>

<c:import url="url" varReader="name" [context="context"][charEncoding="encoding"]></c:import>

下面看个列子：

<%@ page contentType="text/html;charset=GBK"%>

        </c:catch>

        <c:out value="${error3}"></c:out>

    </body>

</html>

浏览器显示：

URL路径有个绝对路径和相对路径。

相对路径：<c:import url="a.txt"/>那么，a.txt必须与当前文件放在同一个文件目录下。如果以"/"开头，表示存放在应用程序的根目录下，如 Tomcat应用程序的根目录文件夹为 webapps。导入该文件夹下的 b.txt 的编写方式： <c:import url="/b.txt">。如果要访问webapps管理文件夹中的其他Web应用，就要用context属性。例如访问demoProj下的 index.jsp，则：<c:import url="/index.jsp" context="/demoProj"/>.

2<c:redirect> 该标签用来实现请求的重定向。例如，对用户输入的用户名和密码进行验证，不成功则重定向到登录页面。或者实现Web应用不同模块之间的衔接

语法：<c:redirect url="url" [context="context"]/>

或：<c:redirect url="url" [context="context"]>

<c:param name="name1" value="value1">

</c:redirect>

来看个列子：

 <body>

    This is my JSP page. <br>

    <c:redirect url="http://127.0.0.1:8080">

        <c:param name="uname">lihui</c:param>

         <c:param name="password">11111</c:param>

3<c:url> 用于动态生成一个 String 类型的URL，可以同上个标签共同使用，也可以使用HTML的<a>标签实验超链接。

语法：<c:url value="value" [var="name"] [scope="..."] [context="context"]>

<c:param name="name1" value="value1">

</c:url>

或：<c:url value="value" [var="name"] [scope="..."] [context="context"]/>

url指定一个jsp文件的地址，jsp会在运行时调用这个jsp。

<%@ page contentType="text/html;charset=GBK"%>

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<c:out value="url标签使用"></c:out>

<h4>

    使用url标签生成一个动态的url，并把值存入session中.
