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 < 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;

}
