cookie例子( 在javascript标签中添加checkCookie();的调用。注：定义函数的代码不会自动运行。)

View Code

<script type="text/javascript">
function getCookie(c_name)
{
if (document.cookie.length>0)
{ 
c_start=document.cookie.indexOf(c_name + "=")
if (c_start!=-1)
{ 
c_start=c_start + c_name.length+1 
c_end=document.cookie.indexOf(";",c_start)
if (c_end==-1) c_end=document.cookie.length

function setCookie(c_name,value,expiredays)

var exdate=new Date()
exdate.setDate(exdate.getDate()+expiredays)
document.cookie=c_name+ "=" +escape(value)+
((expiredays==null) ? "" : "; expires="+exdate.toGMTString())

function checkCookie()

  {alert('Welcome again '+username+'!')}
else 
  {

按钮：

<input type="button" value="View message" onclick="message()" />

文本框

<input type="text" name="lastname">

提交按钮

<input type="submit" value="Submit" />

选择框（当选中其它的值时会产生onchange时间进而调用CreateInput（）函数）

<select name="select" id="select" onchange="CreateInput()" > 
<option value="1">1</option>
<option value="2">2</option>  
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>

时钟（弹出一次）：

function timedMsg()
{
var t=setTimeout("alert('5 秒！')",5000)
}

时钟：

（运行n次其中setTimeout第第一个参数为时间到时运行的代码，不是现实的字符串 clearTimeout(t) 为清除时钟T为setTimeout的返回值）

function timedCount()
{
document.getElementById('txt').value=c
c=c+1
t=setTimeout("timedCount()",1000)
}

时钟：

<html>
<head>
<script type="text/javascript">
function startTime()
{
var today=new Date()
var h=today.getHours()
var m=today.getMinutes()
var s=today.getSeconds()
// add a zero in front of numbers<10
m=checkTime(m)
s=checkTime(s)
document.getElementById('txt').innerHTML=h+":"+m+":"+s
t=setTimeout('startTime()',500)
}

function checkTime(i)
{
if (i<10) 
  {i="0" + i}
  return i
}
</script>
</head>

<body οnlοad="startTime()">
<div id="txt"></div>
