代码样例
import React, { useState, useEffect, useRef } from "react";
import { DatetimePicker, Field } from "react-vant";
const Demo = () => {
const [value, setValue] = useState(null);
return (
<DatetimePicker
popup={{
round: true,
}}
type="date"
title="选择年月日"
minDate={new Date(2021, 0, 1)}
maxDate={new Date(2025, 10, 1)}
value={value}
defaultValue={new Date()}
onConfirm={setValue}
>
{(val, _, actions) => {
return (
<Field
readOnly
clickable
label="选择年月日"
value={val}
placeholder="请选择日期"
onClick={() => actions.open()}
/>
);
}}

);
};

export default Demo;

注意看图片中，默认选择的日期
设置了popup属性

没有设置popup属性

可能问题出现在DatePicker.js的154行const value = props.popup ? formatValue(props.value) : currentDateRef.current; 传递给formatValue的值没有defaultValue
应该参照
DatePicker.js的33行const [currentDate, setCurrentDate, currentDateRef] = useRefState(() => formatValue(value || defaultValue)) 这样给formatValue传值
