首先使用JSP聲明聲明一個函數用於獲得九九乘法表的內容html

<%!
    String printMultiTable() {
        String s = "";
        for (int i = 1; i < 10; i ++) {
            for (int j = 1; j <= i; j ++) 
                s += "&nbsp;" + i + "&nbsp;*&nbsp;" + j + "&nbsp;=&nbsp;" + (i * j) + "&nbsp;";
            s += "<br />";        
        }
        return s;
    }
%>

而後在JSP腳本中使用它：java

<%=printMultiTable() %>

完整的代碼：jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

</head>
<body>
<%!
    String printMultiTable() {
        String s = "";
        for (int i = 1; i < 10; i ++) {
            for (int j = 1; j <= i; j ++) 
                s += "&nbsp;" + i + "&nbsp;*&nbsp;" + j + "&nbsp;=&nbsp;" + (i * j) + "&nbsp;";
            s += "<br />";        
        }
        return s;
    }
%>
