我正在一个项目中，我必须添加一个日期和时间选择器日历。 现在我面临的问题是如何将年份限制为2020年： month =仅当前月份。 日期=从今天到接下来的3天。
可能是我错了，但我想需要更改此代码部分，但不知道如何。因此，正在寻找解决方案。
这是我提到的代码段：
minDateTimeDate = new Date(minDateTime.getFullYear(),minDateTime.getMonth(),minDateTime.getDate(),0);
maxDateTimeDate = new Date(maxDateTime.getFullYear(),maxDateTime.getMonth(),maxDateTime.getDate(),0);
* This function tries to limit the ability to go outside the
* min/max date range
*/

return;
} // No time so nothing to check here
