1.js循环倒计时代码 每5秒循环倒计时到0 再从5秒开始
<script>
var start = 5; var step = -1; function count() { document.getElementById("div1").innerHTML = start; start += step; if(start < 0) start = 5; setTimeout("count()",1000); } window.onload = count; </script> <div id="div1"></div> ---------------------------------------------------------------------------------------------
2.<html>
<head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <title>counter</title> <script language="javascript" type="text/JavaScript"> function Counter(nMax,nInterval) { this.maxTime=nMax; this.interval=nInterval; this.objId="timer"; this.obj=null; this.num=this.maxTime; this.timer=null; this.start=function() { this.obj=document.getElementById(this.objId); if(this.num>0) setTimeout(this.run,this.interval*1000); }; this.run=function() { if(myCounter.num>0) { myCounter.num--; myCounter.obj.innerHTML=myCounter.num; myCounter.timer=setTimeout(myCounter.run,myCounter.interval*1000); } else clearTimeout(myCounter.timer); }; this.show=function() { document.write("<span id="+this.objId+">"+this.num+"</span>"); this.obj=document.getElementById(this.objId); //alert(this.obj.innerHTML); } } </script> </head> <body onload="myCounter.start();">
<script language="JavaScript" type="text/JavaScript">
var myCounter=new Counter(10,1); </script> <p>现在剩下
<script language="JavaScript" type="text/JavaScript"> myCounter.show(); </script> 秒钟!</p> ---------------------------------------------------------------------------------------------
3.
请等待<span id="dd">10</span>秒
<script type="text/javascript"> function run(){ var s = document.getElementById("dd"); if(s.innerHTML == 0){ window.location.href='regform.shtml'; return false; } s.innerHTML = s.innerHTML * 1 - 1; } window.setInterval("run();", 1000); </script> -------------------------------------------------------------------------------------------
