怎样使用javaWeb技术使时间不断的跳动

[lanzhengwu]

什么意思？？
JS特效？显示隐藏：？？

[_重剑无锋_]

js不是有个 setTimeOUt(方法，时间)
让它不停的调用就行了啊

[bati42ta]

假如只是显示一个时间的话，可以用比如

var anIntervalId = null;
function startTime(){
  anIntervalId = setInterval("alert(new Date())",1000);
}

function stopTime(){
  if(anIntervalId)
    clearInterval(anIntervalId);
  anIntervalId = null;
}

我想用线程,有这方法否,给段代码,谢谢

<div id=time></div>
<script>
function show()
{
now=new Date();
year=now.getYear();
month=now.getMonth()+1;
date=now.getDate();
hours=now.getHours();
minutes=now.getMinutes();
seconds=now.getSeconds();
if(minutes<=9)
minutes="0"+minutes
if(seconds<=9)
seconds="0"+seconds
time.innerHTML=year+"年"+month+"月"+date+"日"+"现在时间："+hours+":"+minutes+":"+seconds;

setTimeout("show()",1000);
}
show();
</script>

这样也可以

<span id=liveclock style=position:absolute;left:250px;top:122px;; width: 109px; height: 15px>
</span> （这里可以调整时钟的方位。调用脚本时去掉括号中内容）
<SCRIPT language=javascript>
<!--

function show5(){if(!document.layers&&!document.all)
return
var Digital=new Date()
var hours=Digital.getHours()
var minutes=Digital.getMinutes()
var seconds=Digital.getSeconds()
var dn="AM"
if(hours>12){dn="PM"
hours=hours-12
}if(hours==0)
hours=12
if(minutes<=9)
minutes="0"+minutes
if(seconds<=9)
seconds="0"+seconds
//change font size here to your desire
myclock="<font size='5' face='Arial'><b><font size='1'>Current Time:</font></br>"+hours+":"+minutes+":"
+seconds+" "+dn+"</b></font>"
if(document.layers){document.layers.liveclock.document.write(myclock)
document.layers.liveclock.document.close()
}else if(document.all)
liveclock.innerHTML=myclock
setTimeout("show5()",1000)
}
//>
</SCRIPT>
