<script>
import zhCN from "ant-design-vue/es/locale-provider/zh_CN";
data() {
	return {
		zhCN,
		 yearOptions:[],
         monthOptions:[],
	}
},
methods: {
    getMonthOptions() {
      let monthOptions = []
      for (let i = 0; i <= 11; i++) {
        monthOptions.push({
          label: `${i+1}月`,
          value: i,
        })
      }
      this.monthOptions = monthOptions
    },
    getYearOptions() {
      let yearOptions = []
      for (let i = 2020; i <= new Date().getFullYear()+5; i++) {
        yearOptions.push({
          label: `${i}年`,
          value: i,
        })
      }
      this.yearOptions = yearOptions
    },
        changeYear(value,newYear, onChange) {
      const now =  value.clone().year(newYear)
      onChange(now)

    },
    changeMonth(value,selectedMonth, onChange) {
      const newValue = value.clone()
      newValue.month(parseInt(selectedMonth, 10))
      onChange(newValue)
    },
    prevMonth(value, onChange) {
      let newMonth = moment(value).subtract(1, 'months');
      onChange(newMonth);
    },
    nextMonth(value, onChange) {
      let newMonth = moment(value).add(1, 'months');
      onChange(newMonth);
    },
    showTotay(value,onChange) {
      const today = moment(new Date())
      onChange(today)
    },
}
</script>

效果如下
