How do you generate a random number from JavaScript?

You can either get the time and manipulate that to give you something random or call Math.random(): 

<script language="JavaScript"><!--
today = new Date();
num = today.getTime();
num = Math.round(Math.abs(Math.sin(num) * 1000000));

rand = Math.random()*1000000;
randInt = Math.floor(rand);
// --></script>
