var hours = today.getHours();
var minutes = today.getMinutes();
var seconds = today.getSeconds();
// 从日期对象中中获得时间信息

//将时间字符串组合在一起并写出
var the_time = hours + ":" + minutes + ":" + seconds;
window.document.the_form.the_text.value = the_time; //把表格的值重新写一遍，相当于刷新时间
the_timeout= setTimeout('displayTime();',500); //每半秒钟执行一次该函数,即500毫秒

JS 指定时间 刷新页面
script
setInterval(function(){
var d=new date();
if(d.getFullYear()==2018d.getMonth()==0d.getDate()==27d.getHours()==18d.getMinutes()==0)
location.reload();
},60000);
/script
以上代码只会在指定时间（2018-1-27 18:00:00）刷新一次，如果希望每天的同一时间（比如18点整）都刷新，则
script
setInterval(function(){
var d=new date();
if(d.getHours()==18d.getMinutes()==0)
location.reload();
},60000);
/script
求js指定时间范围对页面进行刷新代码
10到20分钟刷新页面：
setTimeout("location.reload();",parseInt(Math.random()*600000)+600000);

JavaScript简介
JavaScript 是脚本语言
JavaScript 是一种轻量级的编程语言。
JavaScript 是可插入 HTML 页面的编程代码。
JavaScript 插入 HTML 页面后，可由所有的现代浏览器执行。
JavaScript 课外书
如果 JavaScript 教程学习完毕，并且需要更深入地学习这门语言，《JavaScript 高级教程》绝对是您最好的选择。本教程从 JavaScript 的历史开始讲起，直到当前它对 XML 和 Web 服务的支持。
将学习到如何扩展该语言，以使它适应特殊的需求。
还将学到如何使用 JavaScript 创建无缝的客户机 - 服务器通信。
