//-------------可以把以下内容写进外部js文件中------------
window.onload=getTime; //网页加载完就调用getTime()方法
function getTime(){
var today=new Date(); //获取当前系统时间
var hours=today.getHours(); //获取小时
var minutes=today.getMinutes(); //获取分
var seconds=today.getSeconds(); //获取秒
if(minutes10){ //分小于10就在前面补0
minutes="0"+minutes;
}
if(seconds10){ //秒小于10就在前面补0
seconds="0"+seconds;
}
//把时分秒拼起来得到时间
var time =hours+":"+minutes+":"+seconds;
//把时间显示在div上,您自己可以放在网页任何位置,反正时间就是time
document.getElementById("div").innerHTML=time;
//每隔一秒更新一次时间
setTimeout("getTime()",1000);

代码已经贴上，希望对您有帮助
js显示当前日期时间和星期几
JavaScript获取当前日期时间同时显示星期几，具体代码如下：
html
head
meta
http-equiv="Content-Type"
content="text/html;
charset=utf-8"
/
script
type="text/javascript"
src="/jquery/1.7.0/jquery.min.js"/script
script
type="text/javascript"
function
currentTime(){
var
d=new
Date(),str='';
str+=d.getFullYear()+'年';
str+=d.getMonth()
+
1+'月';
str+=d.getDate()+'日';
str+=d.getHours()+'时';
str+=d.getMinutes()+'分';
str+=
d.getSeconds()+'秒';
return
str;
}
setInterval(function(){$('#time').html(currentTime)},1000);
/script
/head
body
div
id="time"/div
/body
/html
在网页上及时动态显示当前的日期时间并显示星期的做法：
function
showTime(){
var
show_day=new
Array('星期一','星期二','星期三','星期四','星期五','星期六','星期日');
var
time=new
Date();
var
year=time.getYear();
var
month=time.getMonth();
var
date=time.getDate();
var
day=time.getDay();
var
hour=time.getHours();
var
minutes=time.getMinutes();
var
second=time.getSeconds();
month10?month='0'+month:month;
month=month+1;
hour10?hour='0'+hour:hour;
minutes10?minutes='0'+minutes:minutes;
second10?second='0'+second:second;
var
now_time='当前时间：'+year+'年'+month+'月'+date+'日'+'
'+show_day[day-1]+'
'+hour+':'+minutes+':'+second;
document.getElementById('showtime').innerHTML=now_time;
setTimeout("showTime();",1000);
}
关于这方面的内容网上很多，有js获取当前日期时间同时显示星期，js获取当前时间和一星期钱的时间等内容，都很具有参考价值，希望大家多阅读类似文章，将类似方法熟练掌握。
js如何获得系统时间年月日时分秒
function showTime() {
var now = new Date();
var nowTime = now.toLocaleString();
var date = nowTime.substring(0,10);//截取日期
var time = nowTime.substring(10,20); //截取时间
var week = now.getDay(); //星期
var hour = now.getHours(); //小时
//判断星期几
var weeks = ["日","一","二","三","四","五","六"];
var getWeek = "星期" + weeks[week];
var sc;
//判断是AM or PM
if(hour = 0 hour 5){
sc = '凌晨';
}
else if(hour 5 hour = 7){
sc = '早上';
}
else if(hour 7 hour = 11){
sc = '上午';
}
else if(hour 11 hour = 13){
sc = '中午';
}
else if(hour 13 hour = 18){
sc = '下午';
}
else if(hour 18 hour = 23){
sc = '晚上';
}
document.getElementById('time').innerHTML ="当前时间：" + date+" " + getWeek +"nbsp;"+" "+sc+" "+time;
setTimeout('showTime()',1000);
}
/script
调用方法:
body onload="showTime()"
div id="time"/div
/body
2.简洁的办法: 显示格式: 当前时间： 2010年6月1日 10:00:00 星期一
htmtl
head/head
body
div id="linkweb" style=" display:inline;"/div
script
setInterval("document.getElementById('linkweb').innerHTML=new Date ().toLocaleString()+' 星期'+'日一二三四五六'.charAt(new Date().getDay ());",1000);
/script
/body
/html
js获得当前日期和时间的代码是什么？
var
myDate
=
new
Date();
myDate.toLocaleDateString()；可以获取当前日期
myDate.toLocaleTimeString();
可以获取当前时间
扩展：
myDate.getYear();
//获取当前年份(2位)
myDate.getFullYear();
//获取完整的年份(4位,1970-????)
myDate.getMonth();
//获取当前月份(0-11,0代表1月)
myDate.getDate();
//获取当前日(1-31)
myDate.getDay();
//获取当前星期X(0-6,0代表星期天)
myDate.getTime();
//获取当前时间(从1970.1.1开始的毫秒数)
myDate.getHours();
//获取当前小时数(0-23)
myDate.getMinutes();
//获取当前分钟数(0-59)
myDate.getSeconds();
//获取当前秒数(0-59)
myDate.getMilliseconds();
//获取当前毫秒数(0-999)
myDate.toLocaleString(
);
//获取日期与时间
js怎么把时间转换成年月日时分秒的形式
需要准备的材料分别有：电脑、html编辑器、浏览器。
1、首先，打开html编辑器，新建html文件，例如：index.html。
2、在index.html中的script标签，输入js代码：var a = 1562060142000;document.body.innerText = new Date(a);。
3、浏览器运行index.html页面，此时时间被转化为年月日时分秒打印出来了。
