JSP生成九九乘法表的簡單實例

一用表達式和腳本方式實現九九乘法表

<%@ page language="java" import="java.util.*" contentType="text/html; charset=utf-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head>  <base href="<%=basePath%>" rel="external nofollow" >    <title>My JSP 'exercise.jsp' starting page</title>      <meta http-equiv="pragma" content="no-cache">    <meta http-equiv="cache-control" content="no-cache">    <meta http-equiv="expires" content="0">      <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">    <meta http-equiv="description" content="This is my page">    <!--    <link rel="stylesheet" type="text/css" href="styles.css" rel="external nofollow" >    -->  </head>  <body>  <%!    //返回九九乘法表對應的HTML代碼，通過表達式來調用，在頁面上顯示    String printMultiTable1()    {     String s = "";     for(int i=1;i<=9;i++)     {       for(int j=1;j<=i;j++)       {        s+=i+"*"+j+"="+(i*j)+"&nbsp;&nbsp;&nbsp;&nbsp;";       }       s+="<br>"; //追加換行標簽     }     return s;    }       //JSP內置out對象，使用腳本方式調用，打印九九乘法表    void printMultiTable2(JspWriter out) throws Exception    {      for(int i=1;i<=9;i++)      {       for(int j=1;j<=i;j++)       {        out.println(i+"*"+j+"="+(i*j)+"&nbsp;&nbsp;&nbsp;&nbsp;");       }       out.println("<br>"); //追加換行標簽     }    }     %>  <h1>九九乘法表</h1>  <hr>  <%=printMultiTable1()%>  <br>  <% printMultiTable2(out);%>  <br>   </body></html>
