Javascript无刷新获取当前时间在项目中需要无刷新更新时间，并且TooTip中显示年月日星期，网上搜集了很多方法，总结一下，以备下次之需。

view sourceprint?<script language="javascript" type="text/javascript">

function ShowTime() {

document.getElementById("time").innerHTML = new Date().toLocaleTimeString(); //获取当前系统时间

setTimeout("ShowTime()", 1000);//设置定时刷新一秒更新一次

}

function DateDemo() {

var d, day = ""; //声明变量

d = new Date(); //创建Date对象
