Acest script va afisa un ceas ca in exemplu de mai jos

abcdefghj

Pentru a adauga acest script intr-o pagina web:
1. Copiati imaginile care compun ceasul de aici -> Imgs; dezarhivati arhiva ".zip" si salvati directorul "imgs" in acelasi loc unde se afla pagina HTML.
2. Introduceti in sectiunea HEAD a documentului HTML urmatorul cod:
<script type="text/javascript">
<!--
var dn
c1=new Image(); c1.src="imgs/c1.gif"
c2=new Image(); c2.src="imgs/c2.gif"
c3=new Image(); c3.src="imgs/c3.gif"
c4=new Image(); c4.src="imgs/c4.gif"
c5=new Image(); c5.src="imgs/c5.gif"
c6=new Image(); c6.src="imgs/c6.gif"
c7=new Image(); c7.src="imgs/c7.gif"
c8=new Image(); c8.src="imgs/c8.gif"
c9=new Image(); c9.src="imgs/c9.gif"
c0=new Image(); c0.src="imgs/c0.gif"
cb=new Image(); cb.src="imgs/cb.gif"
cam=new Image(); cam.src="imgs/cam.gif"
cpm=new Image(); cpm.src="imgs/cpm.gif"

function extract(h,m,s,type){
  if (!document.images)
    return
  if (h<=9) {
    document.images.a.src=cb.src
    document.images.b.src=eval("c"+h+".src")
  }
  else {
    document.images.a.src=eval("c"+Math.floor(h/10)+".src")
    document.images.b.src=eval("c"+(h%10)+".src")
  }
  if (m<=9) {
    document.images.d.src=c0.src
    document.images.e.src=eval("c"+m+".src")
  }
  else {
    document.images.d.src=eval("c"+Math.floor(m/10)+".src")
    document.images.e.src=eval("c"+(m%10)+".src")
  }
  if (s<=9) {
    document.g.src=c0.src
    document.images.h.src=eval("c"+s+".src")
  }
  else {
    document.images.g.src=eval("c"+Math.floor(s/10)+".src")
    document.images.h.src=eval("c"+(s%10)+".src")
  }
  if (dn=="AM") document.j.src=cam.src
  else document.images.j.src=cpm.src
}

function ceas() {
 if (!document.images)
    return
  var Digital=new Date()
  var hours=Digital.getHours()
  var minutes=Digital.getMinutes()
  var seconds=Digital.getSeconds()
  dn="AM"
  if ((hours>=12)&&(minutes>=1)||(hours>=13)) {
    dn="PM"
    hours=hours-12
  }
  if (hours==0)
    hours=12
  extract(hours,minutes,seconds,dn)
  setTimeout("ceas()",1000)
}
//-->
</script>

3. In interiorul tag-ului <body> scrieti onload="ceas()", sa arate asa: <body onload="ceas()">
