在jsp页面中加入java逻辑处理和js的触发事件控制,并且在js中可以直接使用java逻辑中的变量,限于本jsp文件中
example:
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%
String firstname = "wang";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.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">
-->
<script type="text/javascript">
function out()
{
var name = '<%=firstname%>';
alert('MyFirstName: ' + name);
}
</script>
</head>
<body>
This is my JSP page. <br>
<input type = "button" id = "out" name = "out" value = "FromJava" onclick = 'out();'/>
</body>
</html>
本文介绍了一个JSP页面如何结合Java逻辑处理与JavaScript触发事件控制的方法,并演示了如何在JavaScript中直接使用Java逻辑中的变量,实现了按钮点击后显示Java部分定义的名字。
