js生成随机数并在循环里展示

//生成随机数
randomNumBoth(Min, Max) {
        var Range = Max - Min
        var Rand = Math.random()
        var num = Min + Math.round(Rand * Range) //四舍五入
       return num
}

let that = this;
let datas = [];
for (let i = 0; i < that.merchantList.length; i++) {
let datai = that.randomNumBoth(99,96)
datas.push(datai)
}
console.log(datas)
that.dataArr = datas
