急求，一个公司的笔试题

9k的还要做题？

感觉不难啊，座位用双层for渲染吧，每个座位用对象吧，{是否占用，座位编号数组下标}，随机数字选啊，选到了就标记为占用踢出数组，所以这里应该是2个数组吧，一个用来删除继续选座位，一个用来页面展示，思路不太完美，不过这题很简单啊.

vue直接复制格式化
<template> <div> <div v-for="(item, index) in data" :key="index" style="display: flex;justify-content: center;"> <span v-for="item2 in item" :key="item2.id" style="padding:5px;" :style="{ color: item2.isBuy === true ? 'red' : 'black' }">{{ item2.id }}</span> </div> <div style="display: flex;justify-content: center;margin-top:20px;"> <el-button type="primary" @click="buy">购票</el-button> <el-input placeholder="购买多少张" v-model="num" style="width:100px;"></el-input> </div> </div></template>
<script>export default { data() { return { data: [], num: 0, flatData: [], }; }, created() { this.init(); }, methods: { init() { var j = 0; for (let i = 0; i < 10; i++) { for (let i2 = 0; i2 < 10 + i * 2; i2++) { this.data[i] = this.data[i] || []; this.data[i].push({ isBuy: false, id: j++ }); this.flatData.push(this.data[i][i2]); } } console.log(); this.data.reverse(); }, buy() { for (let i = 0; i < this.num; i++) { var randId = this.RandId(); var index = this.flatData.findIndex((item) => item.id === randId); this.flatData[index].isBuy = true; } console.log( "剩余数量", this.flatData.filter((item) => item.isBuy === false) ); }, RandId() { var arr = this.flatData.filter((item) => item.isBuy === false); var id = arr[Math.floor(Math.random() * arr.length)].id; return id; }, },};</script>
<style></style>

这就是问了然后不要你的公司
