随机数组

1.判断在页面是鼠标的click事件还是手机移动端的tap事件

var _click = "ontouchend" in document ? "tap" : "click";

Math.RandomNumbers = function (rn, rcount, bn, bcount) {
    var ret = [];
    var re = [];
    for (var i = 0; i < rcount; i++) {
        ret[i] = Math.ceil(Math.random()*(rn-1)+1);
        ret[i] = ret[i]<10?‘0‘+ret[i]:ret[i];
    }
    for (var i = 0; i < bcount; i++) {
        re[i] = Math.ceil(Math.random()*(bn-1)+1);
        ret.push(re[i]<10?‘0‘+re[i]:re[i]);
    };
    return ret;
}
