本文實例講述了JS動態加載當前時間的方法。分享給大家供大家參考。具體實現方法如下：
<body bgcolor="#fef4d9" onload ="time()"> <script language="JavaScript">function time () { var now = new Date(); var yr = now.getYear(); var mName = now.getMonth() + 1; var dName = now.getDay() + 1; var dayNr = ((now.getDate()<10) ? "0" : "")+ now.getDate(); var ampm = (now.getHours() >= 12) ? " PM" : " AM" var hours = now.getHours(); hours = ((hours > 12) ? hours - 12 : hours); var minutes = ((now.getMinutes() < 10) ? ":0" : ":") + now.getMinutes(); var seconds = ((now.getSeconds() < 10) ? ":0" : ":") + now.getSeconds(); if(dName==1) Day = "星期日"; if(dName==2) Day = "星期一"; if(dName==3) Day = "星期二"; if(dName==4) Day = "星期三"; if(dName==5) Day = "星期四"; if(dName==6) Day = "星期五"; if(dName==7) Day = "星期六"; if(mName==1) Month="1月"; if(mName==2) Month="2月"; if(mName==3) Month="3月"; if(mName==4) Month="4月"; if(mName==5) Month="5月"; if(mName==6) Month="6月"; if(mName==7) Month="7月"; if(mName==8) Month="8月"; if(mName==9) Month="9月"; if(mName==10) Month="10月"; if(mName==11) Month="11月"; if(mName==12) Month="12月"; var DayDateTime=(yr+ "年"+" "+ Month+ dayNr+ "日"+ Day+ " " + hours+ minutes+ seconds+ " "+ ampm ); document.getElementById ("face").innerText=DayDateTime ; timerID = setTimeout("time()",1000); }</script><form id ="form"> <div> <asp:Label ID ="face" runat ="server" ></asp:Label> </div></form></body>希望本文所述對大家的javascript程序設計有所幫助。
