问题
PickerView组件在开发环境可滑动，在测试环境不可滑动
-
正常开发环境是这样正常显示，并且可滑动的
-
发到测试环境后，变成了这样，并且只有中间那列可滑动，两边的都不能滑动，而且还会报警告
-
封装的组件代码如下
javascript">// 日期选择组件
const CustomDatePickerView: FC<any> = ({customizeTab,setCustomizeTime,customizeTime
}) => {const [value, setValue] = useState<number[]>(transformDateToArray(customizeTime[customizeTab]));const [days, setDays] = useState<any>([]);useEffect(() => {// 在组件加载时设置初始值console.log(111, customizeTime, customizeTab, value[0], value[2]);updateDays(value[0], value[2]); // 设置天数列// sessionStorage.setItem('isFirst', '1');}, []);useEffect(() => {setValue(transformDateToArray(customizeTime[customizeTab]));}, [customizeTab]);const months = [{ label: 'January', value: 0 },{ label: 'February', value: 1 },{ label: 'March', value: 2 },{ label: 'April', value: 3 },{ label: 'May', value: 4 },{ label: 'June', value: 5 },{ label: 'July', value: 6 },{ label: 'August', value: 7 },{ label: 'September', value: 8 },{ label: 'October', value: 9 },{ label: 'November', value: 10 },{ label: 'December', value: 11 }];const years = Array.from({ length: 100 }, (_, i) => ({label: `${dayjs().year() - 50 + i}`,value: dayjs().year() - 50 + i}));const updateDays = (month, year) => {const daysInMonth = dayjs(`${year}-${month + 1}`).daysInMonth();const newDays = Array.from({ length: daysInMonth }, (_, i) => ({label: `${i + 1}`,value: i + 1}));setDays(newDays);};const onChange = debounce(val => {const [selectedMonth, selectedDay, selectedYear] = val;if (selectedMonth !== value[0] || selectedYear !== value[2]) {// 动态更新天数列updateDays(selectedMonth, selectedYear);}// 确保日期选项在天数列更新时不越界const daysInSelectedMonth = dayjs(`${selectedYear}-${selectedMonth + 1}`).daysInMonth();if (selectedDay > daysInSelectedMonth) {val[1] = daysInSelectedMonth;}setValue(val);customizeTime[customizeTab] = transformDate(dayjs(`${selectedYear}-${selectedMonth + 1}-${selectedDay}`));setCustomizeTime([...customizeTime]);// }}, 500);return (<PickerViewclassName="!bg-[#27292F]"columns={[months, days, years]}value={value}onChange={onChange}style={{ '--item-font-size': '20px' }}/>);
};
最终发现可能导致的原因是在本地开发环境会触发两次useEffect，所以传入的columns应该没什么问题，而测试环境是只触发一次，打断点的时候发现days这个值不对
解决办法就是 加了一个days.length 的判断就可以了，
javascript">days.length && (<PickerViewclassName="!bg-[#27292F]"columns={[months, days, years]}value={value}onChange={onChange}style={{ '--item-font-size': '20px' }}/>)
