Random URL without repetition

Hey, I have so little java knowledge and I need to use it for my thesis.
I have three websites and I want to randomly generate them. First one works perfectly fine with

<script type="text/javascript">
function randomlinks(){
var myrandom=Math.round(Math.random()*2)
var links=new Array()
links[0]="link1"
links[1]="link2"
links[2]="link3"


window.open(links[myrandom]);
}
</script>

Once one of them is generated, I don't want it to repeat itself.
I have searched a lot, but I do not seem to get a clear answer or I simply do not understand so technical language.
Any help would be appreciated. Thanks in advanced.

The solution would be to remove that link from your array after you've opened it. Take a look at the splice() method.

By the way, did you know that JavaScript and Java are two completely unrelated languages? I'm going to move this to the JavaScript forum.

The mind is a strange and wonderful thing. I'm not sure that it will ever be able to figure itself out, everything else, maybe. From the atom to the universe, everything, except itself.
 
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
