2. js固定时间段触发事件
你所定义的时间，是想用本地时间还是用服务器事件，
如果用本地时间版
vartoday=newDate();
varhour=today.getHours();
if(hour>=8&&hour<9){
//todosomething
}
如果用服务器时权间
vartoday=newDate(${serverTime});//将服务器时间输出到这里
varhour=today.getHours();
if(hour>=8&&hour<9){
//todosomething
}
3. JS如何计算系统当前的时间与预定时间的倒计时
<html>
<head>
<title>倒计时</title>
</head><BODY>
<!--将以下代码加入HTML的<Body></Body>之间-->
<SCRIPT language=JavaScript1.2>
function setcountdown(theyear,themonth,theday){
yr=theyear;mo=themonth;da=theday
}
setcountdown(2006,11,30)
var occasion="2006年11月30日"
var message_on_occasion="盼望已久的时刻终于来到了!"
var countdownwidth='480px'
var countdownheight='20px'
var countdownbgcolor='tan'
var opentags='<font face="宋体"><small>'
var closetags='</small></font>'
var montharray=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec")
var crosscount=''
function start_countdown(){
if (document.layers)
document.countdownnsmain.visibility="show"
else if (document.all||document.getElementById)
crosscount=document.getElementById&&!document.all?document.getElementById("countdownie") : countdownie
countdown()
}
if (document.all||document.getElementById)
document.write('<span id="countdownie" style="width:'+countdownwidth+'; background-color:'+countdownbgcolor+'"></span>')
window.onload=start_countdown
function countdown(){
var today=new Date()
var todayy=today.getYear()
if (todayy < 1000)
todayy+=1900
var todaym=today.getMonth()
var todayd=today.getDate()
var todayh=today.getHours()
var todaymin=today.getMinutes()
var todaysec=today.getSeconds()
var todaystring=montharray[todaym]+" "+todayd+", "+todayy+" "+todayh+":"+todaymin+":"+todaysec
futurestring=montharray[mo-1]+" "+da+", "+yr
dd=Date.parse(futurestring)-Date.parse(todaystring)
dday=Math.floor(dd/(60*60*1000*24)*1)
dhour=Math.floor((dd%(60*60*1000*24))/(60*60*1000)*1)
dmin=Math.floor(((dd%(60*60*1000*24))%(60*60*1000))/(60*1000)*1)
dsec=Math.floor((((dd%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1)

4. 求一段js代码。设置时间段内执行代码
function clock(){
var curr = new Date();
var time = curr.getHours();
if ( time >= 10 && time <16 ){
//do someting
}
}
5. js 如何控制文本域输入内容在一定间隔时间段才触发事件查询相关数据
可以用onpropertychange, 这个函数稿誉皮是输入键差框每键一键就触发，可以在里面判断一下 输入的位数，或规定值，，再虚姿提交后台查询。。
6. 求js指定时间范围对页面进行刷新代码
10到20分钟刷新页面：
setTimeout("location.reload();",parseInt(Math.random()*600000)+600000);
7. 求JS弹窗代码，能再规定时间段内弹出
<SCRIPT LANGUAGE="JavaScript">
var myDate = new Date();
myDate.getYear(); //获取当前年份(2位)
myDate.getFullYear(); //获取完整的年份(4位,1970-????)
myDate.getMonth(); //获取当前月份(0-11,0代表1月)
myDate.getDate(); //获取当前日(1-31)
myDate.getDay(); //获取当前星期X(0-6,0代表星期天)
myDate.getTime(); //获取当前时间(从1970.1.1开始的毫秒数)
myDate.getHours(); //获取当前小时数(0-23)
myDate.getMinutes(); //获取当前分钟数(0-59)
myDate.getSeconds(); //获取当前秒数(0-59)
myDate.getMilliseconds(); //获取当前毫秒数(0-999)
myDate.toLocaleDateString(); //获取当前日期
var mytime=myDate.toLocaleTimeString(); //获取当前时间
myDate.toLocaleString( ); //获取日期与时间
if (mytime<"23:00:00" && mytime>"04:00:00"){
window.open("你要打开的网站");
}
</SCRIPT>
8. html用JS怎么实行定时间刷新页面
js刷新页面可缓腔铅以用定时器加reload去实现。
例：
setInterval(function(){
window.location.reload();
},5000);
这样是每隔五圆橘秒刷新一次扰好当前页面
9. js配送时间按照半小时分段
用setTimeout函数啊搏嫌，你可以散芦设置时间，运行。
所有的订单都先放进一个站基掘手里面，或者数据库，或者表。都行啦。
然后每隔半小时检查一遍符合条件的数据根据需要执行相应的方法不就行了。
