Jeg bruger følgende script for at vide billeder på min hjemmeside, men det er opsat på ugebasis.
Er der nogen som kan fortælle hvordan det gøres således at den viser billeder i 3 uger:

</script> </td><br />
</li>
</ul>
<div align="center">
<script>

var mondayimg="Babe/71.jpg"
var tuesdayimg="Babe/72.jpg"
var wednesdayimg="Babe/73.jpg"
var thursdayimg="Babe/74.jpg"
var fridayimg="Babe/75.jpg"
var saturdayimg="Babe/69.jpg"
var sundayimg="Babe/70.jpg"
var mydate=new Date()
var today=mydate.getDay()
if (today==1)
document.write('<img src="'+mondayimg+'">')
else if (today==2)
document.write('<img src="'+tuesdayimg+'">')
else if (today==3)
document.write('<img src="'+wednesdayimg+'">')
else if (today==4)
document.write('<img src="'+thursdayimg+'">')
else if (today==5)
document.write('<img src="'+fridayimg+'">')
else if (today==6)
document.write('<img src="'+saturdayimg+'">')
else
document.write('<img src="'+sundayimg+'">')
//-->
</script>

Du skal bare bruge følgende script. Husk at udskifte xx med de rigtige billeder:

Kode

<script>
var 0="Babe/xx.jpg";
var 1="Babe/xx.jpg";
var 2="Babe/xx.jpg";
var 3="Babe/xx.jpg";
var 4="Babe/xx.jpg";
var 5="Babe/xx.jpg";
var 6="Babe/xx.jpg";
var 7="Babe/xx.jpg";
var 8="Babe/xx.jpg";
var 9="Babe/xx.jpg";
var 11="Babe/xx.jpg"
var month=mydate.getMonth()
document.write('<img src="'+month+'">')
//-->
</script>

Det kan godt lade sig gøre, men det ville være ret bøvlet. Det er til gengæld let at sætte til en måned. Er det meget vigtigt at det er 3 uger?

Nej det skal ikke være 3 uger, det er en skrivefejl, jeg mente 4 uger,- altså en måned.

Nå oki. Det er jo en anden sag. Der findes en kommando til måned.
Den hedder getMonth.

http://www.w3schools.com/jsref/jsref_getMonth.asp

Du skal bare udskifte denne linie i din kode.:

var today=mydate.getDay()

med denne;

var today=mydate.getMonth()

men husk at den starter på 0, og ikke 1.
