本日做了一个笔试,让及时显现当前时候,返来今后,本身着手敲代码,然则发明一个题目,经由过程getMonth()获得月份,老是会比当前月份少1,深深地以为实践出真知啊……之前以为Date对象挺简朴的,有许多细节都没有注重。此次认认真真又从新看了相关内容,现把须要注重的处所总结以下:1、经由过程getDay()获得的礼拜数是从0最先,0示意礼拜天,以后从1~6顺次示意礼拜一到礼拜六;
2、获得日期需运用getDate()而不是getDay(),由于能够习气性地以为日期就是天数,能够会运用getDay(),但实在getDay()是用于获得礼拜数的;
3、经由过程getMonth()获得月份,从0最先计数,所以须要再加1。
代码以下:
<html>
<head>
<title></title>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<link rel="stylesheet" type="text/css" href="">
<script type="text/javascript"></script>
<style type="text/css">

}
</style>
</head>
<body>
<input id="input">
<script type="text/javascript">
var in_1 = document.getElementById('input');
function showTime(){
var date = new Date();
var week = date.getDay();
var weekday;
switch(week){
case 0: weekday = '礼拜天';break;

}
var year = date.getFullYear();
var month = date.getMonth() + 1;
var day = date.getDate();
var hour = date.getHours();
var minute = date.getMinutes();
var second = date.getSeconds();
var in_1 = document.getElementById('input');
in_1.value = year + '年' + month + "月" + day + '日'+' ' + weekday + ' ' + hour + ':' + minute + ':' + second;
setTimeout(showTime,1000);
}
showTime();
