//This example is to generate an array with 40 random elements, with random values from 0 to 39
for (var a=[],i=0;i<40;++i) a[i]=i;
// http://stackoverflow.com/questions/962802#962890
function shuffle(array) {
var tmp, current, top = array.length;
if(top) while(--top) {
current = Math.floor(Math.random() * (top + 1));
tmp = array[current];
array[current] = array[top];
array[top] = tmp;
}
return array;
}
a = shuffle(a);
Thank you!

Thank you!
