1.组件DateCalendar.vue，sass改为less

      <li
        v-for="(item, index) in calendarTitleArr"
        :key="index"
        class="week-item"
      >
        {{ item }}
      </li>
    </ul>
    <ul class="calendar-view">
      <!-- 动态设置背景颜色 -->
      <li

<template>
  <div>
    <!-- Your template code goes here -->
    <h1>{{ message }}</h1>
    <button @click="changeMessage">Change Message</button>
    <!-- 渲染12个月 -->
    <el-dialog :visible.sync="dialogVisble" width="80%" height="400px">
      <div class="dialog-content">
        <!-- 对话框中的内容 -->
        <!-- 如果内容较多，超出对话框高度，将会出现滚动条 -->
        <date-calendar
          year="2023"
          :month="index"
          v-for="(item, index) in 12"

        />
      </div>
    </el-dialog>
  </div>
</template>

<script>
import DateCalendar from "@/components/DateCalendar.vue";
export default {
  components: {
    "date-calendar": DateCalendar,
  },
  data() {
    return {
      dialogVisble: false,
      message: [],
      pollutionData: [
        {
          time: "2023-01-02",
          pollution: "休息日",
          value: "0",
        },
        {
          time: "2023-01-01",
          pollution: "工作日",
          value: "1",
        },
      ],
    };
  },
  methods: {
    changeMessage() {
      this.dialogVisble = true;
    },
  },
};
</script>

<style scoped>
/* Your component-specific styles go here */
h1 {
  color: blue;
}
.dialog-content {
  max-height: 300px; /* 设置最大高度，超过该高度将出现滚动条 */
  overflow-y: auto; /* 添加垂直滚动条 */
  padding: 10px; /* 可选：为内容添加一些内边距，使样式更美观 */
}
</style>

效果：
vue 日历月平铺开展示,vue,开发语言,前端,less
样式之后再调~~
参考文章开头的链接，实现按年度进行12个月的日历平铺，并且按数组给值标记工作日和休息日。文章来源地址https://www.toymoban.com/news/detail-807126.html
