我有nuxt.js应用,该应用使用vuejs-datepicker:
<template>
<!-- ... -->
<DatePicker :value="datePicker.value" />
<!-- ... -->
</template>
和一系列日期变量:
<script>
import DatePicker from 'vuejs-datepicker'
import { DateTime } from 'luxon'
const moment = require('moment')
const date = new Date(2016, 8, 16)
const date2 = moment('2016-09-16').toDate()
const date3 = DateTime.local(2016, 9, 16).toJSDate()
export default {
components: {
DatePicker
},
data() {
return {
datePicker: {
mondayFirst: true,
format: 'dd.MM.yyyy',
value: date
}
}
}
}
当我将其“值”属性绑定到通常的日期变量“ date”时,一切正常,但是当我选择date2或date3时,会收到此烦人的警告
[Vue warn]: Invalid prop: custom validator check failed for prop "value".

我发现了用于value属性的自定义验证器,它非常简单明了,在所有三种情况下都返回true:
value: {
validator: function (val) { return utils$1.validateDateInput(val); }
}
...
validateDateInput (val) {
return val === null || val instanceof Date || typeof val === 'string' || typeof val === 'number'
}
但是有什么区别呢?可能是Vue.js错误本身吗?
答案 0 :(得分:1)
date2
和date3
是对象,而value需要为null |日期|字符串数字
const date2 = moment('2016-09-16').toDate()
const date3 = DateTime.local(2016, 9, 16).toJSDate()
typeof date2 // object
typeof date3 // object
您应使用.toString()
将其转换为字符串
const date2 = moment('2016-09-16').toString()
const date2 = moment('2016-09-16').toISOString()
const date3 = DateTime.local(2016, 9, 16).toString()
或使用Unix时间戳
const date2 = moment('2016-09-16').unix()
const date3 = moment('2016-09-16').valueOf()
const date4 = moment('2016-09-16').getTime()
const date5 = DateTime.local(2016, 9, 16).valueOf()
