jsp基本语法
jsp工作原理
演示：
<%@page import="java.text.SimpleDateFormat"%>
<%@page import="java.util.Date"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>获取当前日期</title>
</head>
<body>
当前日期为：
<%
SimpleDateFormat dd = new SimpleDateFormat("yyyy年MM月dd日");
String dateTime = dd.format(new Date());
%>
<%=dateTime%>
</body>
</html>
表单提交方式
演示：
<form name="form1" method="post" action="reginfo.jsp">
<table border="0" align="center">
<tr>
<td>用户名</td>
<td><input type="text" name="name"></td>
</tr>
<tr>
<td>密码</td>
<td><input type="password" name="pwd"></td>
</tr>
<tr>
<td>你从哪里知道卓京</td>
<td><input type="checkbox" name="channel" value="报刊">报刊
<input type="checkbox" name="channel" value="网络">网络 <input
type="checkbox" name="channel" value="朋友推荐"> 朋友推荐 <input
type="checkbox" name="channel" value="电视"> 电视</td>
</tr>
</table>
</form>
jsp内置对象
演示：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>時間點擊事件</title>
<style type="text/css">
button {
color: pink
}
</style>
<script type="text/javascript">
function dianji() {
window.setInterval(function dianji() {
var odiv = document.getElementById("odiv");
var date = new Date();
var hour = date.getHours();
var minues = date.getMinutes();
var second = date.getSeconds();
odiv.innerHTML = "时间为：" + hour + ":" + minues + ":" + second;
}, 1000)
}
</script>
</head>
<body>
<div id="odiv">
<button onclick="dianji()">点击一下</button>
</div>
