关于javascript:模拟彩票抽取vuejs

最近在买双色球，据说流言头奖中奖号码是这一期所有号码组合中注数起码的一个，基于大部分人都是机选买彩票，所以写了代码如下模仿彩票抽奖后果。
图个乐子，早上下班跑起来，上班看下后果再去买，哈哈
代码如下

<template>
  <div class="detail-page-box">
    <span> {{count}} </span>
    <button @click="alertResult"> 点我进行，并计算 </button>
  </div>
</template>
<script lang="ts">
import {Component, Vue, Watch, Prop} from "vue-property-decorator";
import {Search, Toast} from "vant";
let timer: any;
@Component({
  components: {"van-search": Search,},
})
export default class CardItem extends Vue {@Prop() boxWidth: any;
  @Prop({default: false}) ifShowCancel!: boolean;
  count: number = 0;
  allList: any = {};
  guess() {
    this.count++;
    let str = "";
    let numEdList: any = [];
    for (let i = 0; i < 7; i++) {if (i < 6) {let randomNum:any = Math.floor(Math.random() * 35 + 1);
        while (numEdList.includes(randomNum)) {randomNum = Math.floor(Math.random() * 35 + 1);
        }
        if (randomNum < 10) {str +=""+"0" + randomNum;} else {str +=" "+ randomNum;}
        numEdList.push(randomNum);
      } else {let randomNum = Math.floor(Math.random() * 15 + 1);
        if (randomNum < 10) {str +=""+"0" + randomNum;} else {str +=" "+ randomNum;}
      }
    }

    if (!this.allList[str]) {this.allList[str] = 1;
    } else {this.allList[str]++;
    }
  }
  alertResult() {
    let minCombination: any = "";
    let minNum: number = 0;
    clearInterval(timer);
    Object.keys(this.allList).forEach((item, index) => {if (index === 0) {minNum = this.allList[item];
        minCombination = item;
      } else {if (minNum > this.allList[item]) {minNum = this.allList[item];
          minCombination = item;
        }
      }
    });
    alert(` 最小注数为：` + minNum + ` 号码组合为：` + minCombination);
  }
  created() {timer = setInterval(this.guess, 500);
  }
}
</script>
<style lang="less" scoped>
.detail-page-box {
  text-align: center;
  line-height: 100px;
}
</style>

效果图比拟简陋如下

以及点击后果后图片如下，最初一个号码为蓝球，前六个为红球
