//————-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);

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。
