组合API中的样式可以隐藏对象

Question

hi我以前使用Options API，我将代码完全转换为composition API，但现在我在隐藏原始对象的样式方面遇到了问题。我不知道这两个API之间有什么不同，但不应影响样式。这是我在两个API中的两个例子首先是composition api

<script setup>
import {
QCalendarDay,
addToDate,
parseTimestamp,
isBetweenDates,
today,
parsed,
parseTime
} from '@quasar/quasar-ui-qcalendar/src/index.js'

import { ref ,computed} from 'vue'
import NavigationBar from '../components/NavigationBar.vue'
const calendar=ref(null)
const  selectedDate=ref(today())
const events=ref([

Answer 1

通过将.value添加到const events = eventsMap.value[ dt ] || []来修复
