复制代码代码如下://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 ret[i] = HF.Math.Random(startNum, endNum);}return ret;}var tmp = [];var i = 0;for (var s = startNum; s tmp[i++] = s;}var l = tmp.length;for (i = 0; i ret[i] = HF.Array.Remove(tmp, HF.Math.Random(0, --l));}return ret;}
