在jsp中用javascript实现
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Insert title here</title>
</head>
<body>
<input type="text" name="time" id="mypwd">
<script type="text/javascript">
window.onload = function(){
showTime();
}
function showTime(){
var myDate = new Date();
var year = myDate.getFullYear();
var month = myDate.getMonth() + 1;
var date = myDate.getDate();
var dateArr = ["日","一",'二','三','四','五','六'];
var day = myDate.getDay();
var hours = myDate.getHours();
var minutes = formatTime(myDate.getMinutes());
var seconds = formatTime(myDate.getSeconds());
var systemTime = document.getElementById("time");
systemTime.innerHTML = " " + year + "年" + month +"月" + date + "日" + " " + hours + ":" + minutes ;
setTimeout("showTime()",500);
document.getElementById("mypwd").value = document.getElementById("time").innerHTML;
}
//格式化时间：分秒。
function formatTime (i){
if(i < 10){
i = "0" + i;
}
return i;
}
</script>
<div id="time"></div>
</body>
</html>
