这篇文章主要介绍了JavaScript在浏览器标题栏上显示当前日期和时间的方法,实例分析了javascript操作时间及DOM节点实现定时触发的技巧,非常具有实用价值,需要的朋友可以参考下
本文实例讲述了JavaScript在浏览器标题栏上显示当前日期和时间的方法,分享给大家供大家参考。具体如下:
将这段脚本放到head区即可:
- <script language="JavaScript">
- <!--
- function resetIt() {
- // Calculate Time
- var timerID = null;
- var timerRunning = false;
- if(timerRunning)
- clearTimeout(timerID);
- timerRunning = false;
- // getTime
- var timeNow = new Date();
- var hours = timeNow.getHours();
- var minutes = timeNow.getMinutes();
- var seconds = timeNow.getSeconds();
- var timeValue = "" + ((hours >12) ? hours -12 :hours)
- timeValue = ((timeValue <10)? "0":"") + timeValue
- timeValue += ((minutes < 10) ? ":0" : ":") + minutes
- timeValue += ((seconds < 10) ? ":0" : ":") + seconds
- timeValue += (hours >= 12) ? " PM" : " AM"
- timerID = setTimeout("resetIt()",100);
- timerRunning = true;
- // getDate
- var dateNow = new Date();
- var days = new Array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');
- var months = new Array('January','February','March','April','May','June','July','August','September','October','November','December');
- var date = ((dateNow.getDate()<10) ? "0" : "")+ dateNow.getDate();
- function y2k(number){return (number < 1000) ? number + 1900 : number;}
- // compileIt
- today = timeValue + " " + days[dateNow.getDay()] + " " +
- months[dateNow.getMonth()] + ", " +
- date + " " +
- (y2k(dateNow.getYear()));
- if(document.all || document.getElementById){ // Browser Check
- document.title = today.toString();
- }else{
- self.status = today.toString(); // Default to status.
- }
- }
- resetIt();
- //-->
- </script>
希望本文所述对大家的javascript程序设计有所帮助。
