在krystalcampioni/vue-out datepicker中，如何以编程方式设置入住和退房日期？

<template>
  <div>
    <datepicker v-model="checkInDate"></datepicker>
    <datepicker v-model="checkOutDate"></datepicker>
  </div>
</template>

<script>
export default {
  data() {
    return {
      checkInDate: null,
      checkOutDate: null
    };
  }
};
</script>

methods: {
  setDates() {
    // 设置入住和退房日期
    this.checkInDate = new Date('2022-01-01');
    this.checkOutDate = new Date('2022-01-07');
  }
}

mounted() {
  this.setDates();
}
