在VanDatetimePicker关闭后,可以使用ref获取VanDatetimePicker组件实例,在组件实例中调用reset方法来恢复默认值。
示例代码:
```
<template>
<van-datetime-picker
v-model="currentDate"
ref="datetimePicker"
title="选择日期时间"
type="datetime"
:min-date="minDate"
:max-date="maxDate"
@confirm="onConfirm"
@cancel="onCancel"
/>
</template>
<script>
import { ref } from 'vue';
import { DatetimePicker } from 'vant';
export default {
components: {
[DatetimePicker.name]: DatetimePicker,
},
setup() {
const currentDate = ref(new Date());
const minDate = ref(new Date(new Date().getFullYear() - 10, 0, 1));
const maxDate = ref(new Date(new Date().getFullYear() + 10, 11, 31));
const datetimePickerRef = ref(null);
const onConfirm = () => {
console.log(currentDate.value);
};
const onCancel = () => {
datetimePickerRef.value.reset();
};
return {
currentDate,
minDate,
maxDate,
datetimePickerRef,
onConfirm,
onCancel,
};
},
};
</script>
```
在上面的代码中,我们通过ref获取了VanDatetimePicker组件实例,并将其赋值给datetimePickerRef变量。然后,在VanDatetimePicker组件的取消事件中,我们调用了datetimePickerRef.value.reset()方法来恢复默认值。
