?JS的强大之一:动态实现后台系统时间的显示
?????? 用js显示当先系统时间是大多数网站都会有的,尤其是在后台,当前时间不可缺少,有了时间管理员可以在管理用户等一些操作的时候,清楚的知道当前的准备时间。最近我们要做一个网站,后台需要显示当前系统时间。我就写了写,以下是具体的代码。

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>MyHtml.html</title> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="this is my page"> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <!--<link rel="stylesheet" type="text/css" href="./styles.css">--> <SCRIPT type=text/javascript> window.onload = function() { alert("进行测试z_xiaofei168"); var clock = new Clock(); clock.display(document.getElementById("clock")); } function Clock() { var date = new Date(); this.year = date.getFullYear(); this.month = date.getMonth() + 1; this.date = date.getDate(); this.day = new Array("星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六")[date.getDay()]; this.hour = date.getHours() < 10 ? "0" + date.getHours() : date.getHours(); this.minute = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes(); this.second = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds(); this.toString = function() { return "现在是:" + this.year + "年" + this.month + "月" + this.date + "日 " + this.hour + ":" + this.minute + ":" + this.second + " " + this.day; }; this.toSimpleDate = function() { return this.year + "-" + this.month + "-" + this.date; }; this.toDetailDate = function() { return this.year + "-" + this.month + "-" + this.date + " " + this.hour + ":" + this.minute + ":" + this.second; }; this.display = function(ele) { var clock = new Clock(); ele.innerHTML = clock.toString(); window.setTimeout(function() {clock.display(ele);}, 1000); }; } </SCRIPT> </head> <body> <span id="clock"></span> </body> </html>
