jsp将变量传递给javascript函数

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!
