JavaScript在浏览器标题栏上显示当前日期和时间的方法

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 Timevar timerID = null;var timerRunning = false;if（timerRunning）clearTimeout（timerID）;timerRunning = false;// getTimevar 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":""） + timeValuetimeValue += （（minutes < 10） ? ":0" : ":"） + minutestimeValue += （（seconds < 10） ? ":0" : ":"） + secondstimeValue += （hours >= 12） ? " PM" : " AM"timerID = setTimeout（"resetIt（）",100）;timerRunning = true;// getDatevar 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;}// compileIttoday = 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。
