我是用在VUE的项目中，lowRange为范围最小值，highRange为范围最大值，numArry为你要保存随机数的数组
代码如下：

changeNum() {
            if (this.stop) {
                return
            }
     
            this.timeOut = setTimeout(() => {
                if (this.stop) {
                    this.numArry = this.deleteTheSameNum(this.lowRange, this.highRange, this.numArry)
                    if (this.timeOut) {
                        this.timeOut = null
                        clearTimeout(this.timeOut)
                    }
                    return
                }
                for (let i = 0; i < this.numArry.length; i++) {
                    this.$set(this.numArry, i, parseInt(Math.random() * this.highRange + this.lowRange))
                    // this.numArry[i].num = parseInt(Math.random() * this.highRange + this.lowRange)
                }
                this.changeNum();
            }, 100);
        },

 deleteTheSameNum(start, end, arry) {
            if (!Array.isArray(arry)) return
            let newSet = new Set(arry)
            if (newSet.size === arry.length) return arry
            while (newSet.size !== arry.length) {
                newSet.add(parseInt(Math.random() * end + start))
            }
            return [...newSet]
        }
