静态包含——动态包含

include.jsp

<%@ page contentType="text/html" pageEncoding="utf-8"%>
<html>
    <head><title>frfrfr</title></head>
    <body>
        <h1>静态包含</h1>
        <h3><%@ include file = "info.html"%></h3>
        <h3><%@ include file = "info.jsp"%></h3>
        <h3><%@ include file = "info.inc"%></h3>
    </body>
</html>

info.html

 <h2><font color = "red">info.html</font></h2>

info.ioc

 <h2><font color = "blue">info.inc</font></h2>

info.jsp

 <h2><font color = "blue">info.inc</font></h2>

静态包含直接替换。

 

 

动态包含：

der.jdp

<%@ page contentType="text/html" pageEncoding="utf-8"%>
<html>
    <head><title>frfrfr</title></head>
    <body>
        <h1>动态包含</h1>
        <jsp:include file = "info.html"/>
        <jsp:include file = "info.jsp"/>
        <jsp:include file = "info.inc"/>
    </body>
</html>

demo.jsp

<%@ page contentType="text/html" pageEncoding="GBK"%>
<html>
<head><title>www.mldnjava.cn，MLDN高端Java培训</title></head>
<body>
    <h1>动态包含操作</h1>
    <%
        String username = "lop" ;
    %>
    <jsp:include page="receive_param.jsp">
        <jsp:param name="name" value="<%=username%>"/>
        <jsp:param name="info" value="www.mldnjava.cn"/>
    </jsp:include>
</body>
</html>
receive_param.jsp
<%@ page contentType="text/html" pageEncoding="GBK"%>
<h1>参数一：<%=request.getParameter("name")%></h1>
<h1>参数二：<%=request.getParameter("info")%></h1>

静态变量重复

demo4.jsp

<%@ page contentType="text/html" pageEncoding="GBK"%>
<html>
<head><title>yyy</title></head>
<body>
    <%
        int x = 100 ;    // 变量重复
    %>
    <h1>demo04.jsp -- <%=x%></h1>
    <%@include file="include.jsp"%>
</body>
</html>

include.jsp

<%
    int x = 10 ;
%>
<h1>include.jsp -- <%=x%></h1>

这样会出错。

动态变量的重复：

<%@ page contentType="text/html" pageEncoding="GBK"%>
<html>
<head><title>www.mldnjava.cn，MLDN高端Java培训</title></head>
<body>
    <%
        int x = 100 ;    // 变量重复
    %>
    <h1>include_demo04.jsp -- <%=x%></h1>
    <jsp:include page="include.jsp"/>
</body>
</html>

动态包含变量名重复是可以的。

 

标签必须完结
