A simple example of generating a _javascript random array with JS technique

A simple example of generating a random array without duplicates

Gets the random number//hf in the array
. Math.randomnumbers is a prefix that can be defined by itself, mainly looking at the logical code
HF. Math.randomnumbers = function (Startnum, Endnum, Count, repeat) {
  var ret = [];
  if (repeat) {for
    (var i = 0; i < count; i++) {
      Ret[i] = HF. Math.random (Startnum, endnum);
    }
    return ret;
  }
  var tmp = [];
  var i = 0;
  for (var s = startnum s <= endnum; s++) {
    tmp[i++] = s;
  }
  var L = tmp.length;
  for (i = 0; i < count; i++) {
    Ret[i] = HF. Array.remove (TMP, HF. Math.random (0,--l));
  return ret;
}

The above is a simple example of a random array of JS generation is a small series to share all the content of everyone, hope to give you a reference, but also hope that we support the cloud-dwelling community.
