| 特效名称:按钮上的时间 |
| 实现此效果你需要进行如下 3 步操作: [查看演示效果] |
|
| 第1步:将以下代码加到〈head〉与〈/head〉之间 |
<script language="JavaScript">
var timerID = null;
var timerRunning = false;
// Called by both onLoad in BODY tag, and Resume button.
function startclock ()
{
// Make sure the clock is stopped
stopclock();
time();
}
// Kills clock.
function stopclock ()
{
if(timerRunning)
clearTimeout(timerID);
timerRunning = false;
}
function time ()
{
var now = new Date();
var yr = now.getYear();
var mName = now.getMonth() + 1;
var dName = now.getDay() + 1;
var dayNr = ((now.getDate()<10) ? "0" : "")+ now.getDate();
var ampm = (now.getHours() >= 12) ? " P.M." : " A.M."
var hours = now.getHours();
hours = ((hours > 12) ? hours - 12 : hours);
var minutes = ((now.getMinutes() < 10) ? ":0" : ":") + now.getMinutes();
var seconds = ((now.getSeconds() < 10) ? ":0" : ":") + now.getSeconds();
if(dName==1) Day = "Sunday";
if(dName==2) Day = "Monday";
if(dName==3) Day = "Tuesday";
if(dName==4) Day = "Wednesday";
if(dName==5) Day = "Thursday";
if(dName==6) Day = "Friday";
if(dName==7) Day = "Saturday";
if(mName==1) Month="January";
if(mName==2) Month="February";
if(mName==3) Month="March";
if(mName==4) Month="April";
if(mName==5) Month="May";
if(mName==6) Month="June";
if(mName==7) Month="July";
if(mName==8) Month="August";
if(mName==9) Month="September";
if(mName==10) Month="October";
if(mName==11) Month="November";
if(mName==12) Month="December";
// String to display current date.
var DayDateTime=(" "
+ Day
+ " "
+ Month
+ " "
+ dayNr
+ ", "
+ ""
+ yr
+ " "
+ hours
+ minutes
+ seconds
+ " "
+ ampm
);
// Displays Day-Date-Time on the staus bar.
document.clock.face.value=DayDateTime;
timerID = setTimeout("time()",1000);
timerRunning = true;
}
// Stops clock and clears status bar.
function clearStatus()
{
if(timerRunning)
clearTimeout(timerID);
timerRunning = false;
window.status=" ";
}
// -- End Hiding Here -->

| <body bgcolor="#fef4d9" onLoad="startclock ()"> |
| 第3步:将以下代码加到〈body〉与〈/body〉之间 |
<form name="clock" onSubmit="0">
