实现5*5正方形网格x轴和y轴显示对应数值组件封装

需求：按5*5的正方形网格，根据目标数据的x和y轴值显示对应的文字，实现效果图如下：（当前目标数值：x=2，y=2）

代码如下：

vue 复制代码
<template>
  <div class="box">
    <div class="box-item" v-for="(item, index) in itemList" :key="index" :class="item.className">
      {{ (x === item.x && y === item.y) ? item.label : '' }}
    </div>
  </div>
</template>

<script setup lang="ts">
withDefaults(defineProps<{
  x?: number,
  y?: number
}>(), {
  x: 2,
  y: 2
})

interface itemType {
  className: string;
  label: string;
  x: number;
  y: number;
}
let itemList: itemType[] = Array.from({ length: 25 }).map((_, index) => {
  let result = {
    className: '',
    label: '中',
    x: 0,
    y: 0
  }
  if ([3, 4, 8, 9, 14].includes(index)) {
    result.className = 'blue'
    result.label = '高'
  } else if ([10, 15, 16, 20, 21].includes(index)) {
    result.className = 'orange'
    result.label = '低'
  }
  result.className += ` xy-${index}`
  return result
})
let Y = 10
for (let j = 0; j < 25; j += 5) {
  for (let i = j; i < j + 5; i++) {
    if ([0, 5, 10, 15, 20].includes(i)) {
      itemList[i].x = 2
    } else {
      itemList[i].x = itemList[i - 1].x + 2
    }
    itemList[i].y = Y
  }
  Y -= 2
}
</script>
