下面例子展示了如何将jsp中的变量传递给javascript函数进行处理：

<%@ page language="java" import="java.util.*" pageEncoding="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%>">
    
    <title>select页面</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">
    -->

<script type="text/javascript" language="javascript">
    function test(val)
    {
        alert(val);
    }
</script>
  </head>
  
  
  <body>
    <%String message = "Hello World!";%>
   <input type="button"  value="确定" style="width:40px;height:20px;" onclick="test('<%=message%>')"> 
  </body>
</html>

单击确定后，页面会弹出Hello World!
