JS生成不重复随机数组的函数代码

//获取数组中的随机数
//HF.Math.RandomNumbers是前缀，可以自己定义，主要看逻辑代码
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;
}
