The link is working fine, what I am trying to tell you with this link might not be clear.
For going a little bit deeper into this: Think about what elements should be accessed randomly, then use the _collect API to store these elements in an array. Then create your random index with Math.random like it has been done here

function getRandom(min, max) {
 if(min > max) {
  return -1;
 }
 
 if(min == max) {
  return min;
 }
 
 var r;
 
 do {
  r = Math.random();
 }
 while(r == 1.0);
 
 return min + parseInt(r * (max-min+1));
}
