(New Date (). GetTime ()) ^ math.random ();

Random and basically hard to repeat ...
It's better to forget it. Randomly generated numbers that are not duplicated and are arranged from large to small.
<script> function Create (n) {var temp=math.floor (MATH.R Andom () *10+n*10); while (--n!=0) {return temp+ "," +create (n); } if (n==0) {return temp; Alert (Create (10)); </script>
