2. js固定時間段觸發事件
你所定義的時間，是想用本地時間還是用伺服器事件，
如果用本地時間版
vartoday=newDate();
varhour=today.getHours();
if(hour>=8&&hour<9){
//todosomething
}
如果用伺服器時權間
vartoday=newDate(${serverTime});//將伺服器時間輸出到這里
varhour=today.getHours();
if(hour>=8&&hour<9){
//todosomething
}
3. JS如何計算系統當前的時間與預定時間的倒計時
<html>
<head>
<title>倒計時</title>
</head><BODY>
<!--將以下代碼加入HTML的<Body></Body>之間-->
<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="盼望已久的時刻終於來到了!"
var countdownwidth='480px'
var countdownheight='20px'
var countdownbgcolor='tan'
var opentags='<font face="宋體"><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代碼。設置時間段內執行代碼
function clock(){
var curr = new Date();
var time = curr.getHours();
if ( time >= 10 && time <16 ){
//do someting
}
}
5. js 如何控制文本域輸入內容在一定間隔時間段才觸發事件查詢相關數據
可以用onpropertychange, 這個函數稿譽皮是輸入鍵差框每鍵一鍵就觸發，可以在裡面判斷一下 輸入的位數，或規定值，，再虛姿提交後台查詢。。
6. 求js指定時間范圍對頁面進行刷新代碼
10到20分鍾刷新頁面：
setTimeout("location.reload();",parseInt(Math.random()*600000)+600000);
7. 求JS彈窗代碼，能再規定時間段內彈出
<SCRIPT LANGUAGE="JavaScript">
var myDate = new Date();
myDate.getYear(); //獲取當前年份(2位)
myDate.getFullYear(); //獲取完整的年份(4位,1970-????)
myDate.getMonth(); //獲取當前月份(0-11,0代表1月)
myDate.getDate(); //獲取當前日(1-31)
myDate.getDay(); //獲取當前星期X(0-6,0代表星期天)
myDate.getTime(); //獲取當前時間(從1970.1.1開始的毫秒數)
myDate.getHours(); //獲取當前小時數(0-23)
myDate.getMinutes(); //獲取當前分鍾數(0-59)
myDate.getSeconds(); //獲取當前秒數(0-59)
myDate.getMilliseconds(); //獲取當前毫秒數(0-999)
myDate.toLocaleDateString(); //獲取當前日期
var mytime=myDate.toLocaleTimeString(); //獲取當前時間
myDate.toLocaleString( ); //獲取日期與時間
if (mytime<"23:00:00" && mytime>"04:00:00"){
window.open("你要打開的網站");
}
</SCRIPT>
8. html用JS怎麼實行定時間刷新頁面
js刷新頁面可緩腔鉛以用定時器加reload去實現。
例：
setInterval(function(){
window.location.reload();
},5000);
這樣是每隔五圓橘秒刷新一次擾好當前頁面
9. js配送時間按照半小時分段
用setTimeout函數啊搏嫌，你可以散蘆設置時間，運行。
所有的訂單都先放進一個站基掘手裡面，或者資料庫，或者表。都行啦。
然後每隔半小時檢查一遍符合條件的數據根據需要執行相應的方法不就行了。
