用vue写一个日历组件

好的，我可以为您提供一些Vue.js的日历组件代码示例：

<template>
  <div>
    <h2>Calendar</h2>
    <table>
      <thead>
        <tr>
          <th v-for="day in daysOfWeek">{{ day }}</th>
        </tr>
      </thead>
      <tbody>
        <tr v-for="week in weeks">
          <td v-for="day in week">
            <div v-if="day">
              <span>{{ day.date }}</span>
            </div>
          </td>
        </tr>
      </tbody>
    </table>
  </div>
</template>

<script>
export default {
  data() {
    return {
      daysOfWeek: ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"],
      today: new Date(),
      currentMonth: null,
      currentYear: null,
      weeks: [],
    };
  },
  mounted() {
    this.setCurrentDate();
    this.createCalendar();
  },
  methods: {
    setCurrentDate() {
      this.currentMonth = this.today.getMonth();
      this.currentYear = this.today.getFullYear();
    },
    createCalendar() {
      const weeks = [];
      let firstDayOfMonth = new Date(this.currentYear, this.currentMonth, 1).getDay();
      let lastDateOfMonth = new Date(this.currentYear, this.currentMonth + 1, 0).getDate();
      let day = 1;
      for (let i = 0; i < 6; i++) {
        const week = [];
        for (let j = 0; j < 7; j++) {
          if (i === 0 && j < firstDayOfMonth) {
            week.push(null);
          } else if (day > lastDateOfMonth) {
            break;
          } else {
            week.push({ date: day });
            day++;
          }
        }
        weeks.push(week);
        if (day > lastDateOfMonth) {
          break;
        }
      }
      this.weeks = weeks;
    },
  },
};
</script>

这个日历组件可以显示当前月份的日历，以周日为每周的第一天。您可以根据自己的需求进行修改。
