23、按钮上的时间代码

脚本说明:

第一步:把如下代码加入<body>区域中

<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 -->

</script>

 

<form name="clock" onSubmit="0">

<input type=button name="face" size=100 value=" JavaScript!!  ">

</form>

 

 

第二步:<body>中的内容改为:

<body bgcolor="#fef4d9" onLoad="startclock ()">
