return a random amount of quotes

[rbrown]

hi,

just wondering if someone could assist me modify this script to display a random amount of quotes?

i.e. sometimes it might return and display 2 quotes, then 1 quote, then maybe 3 quotes?

rather than it is now, 1 quote per time.

<script type="text/javascript">
<!--
//I. Array of banner that will randomly appear

var randomquote = new Array ( );
randomquote[0] = '<em>"Nothing is more fairly distributed than common sense: no one thinks he needs more of it than he already has."</em><br/><br/><span class="alignright">-- Rene Descartes</span>';
randomquote[1] = '<em>"Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more."</em><br/><br/><span class="alignright">-- Nikola Tesla</span>';
randomquote[2] = '<em>"Better to illuminate than merely to shine, to deliver to others contemplated truths than merely to contemplate."</em><br/><br/><span class="alignright">-- Thomas Aquinas</span>';

//II. function to generate number from 0 to n

function randomzero (n)
{
  return ( Math.floor ( Math.random ( )*0.9999999999999999* (n + 1)) );
}

//III. assign any random number from 0 to 2 to x.

x = randomzero(2);

//IV. display the text 

document.write(randomquote[x]);
//-->

</script>

thanks!!!

I changed the x variable to an array and the rest of the script to reflect the change. Note that Math.random never return exactly 1.
