JSP指令与动作元素

1、include指令:

  语法:

  <%@ include file = "URL" %>

2、include动作:

  语法:

  <jsp:include page = "URL" flush = "true|false" />

    说明:page:要包含的页面;

       flush:被包含的页面是否从缓冲区读取;

3、include指令与include动作比较:

  

 

4、forward动作:

  语法:

  <jsp:forward page = "URL" />

  等同于:

  request.getRequestDispatcher("/url").forward(request,response);

 

5、param动作:

  语法:

  <jsp:param name = " 参数名"  value = "参数值" >

  常与<jsp:forward >一起使用,作为其的子标签。
