推荐答案
date2 [i]不是Date对象.您需要将其强制转换为Date对象(新的Date(value))或使用primeng日历属性dataType ="string"并仅使用字符串.顺便说一句，我遇到了同样的错误并花了几个小时
date2[i] is not a Date object. You need it to cast it to Date Object before that ( new Date(value) or use primeng calendar property dataType="string" and work with strings only. Btw i got same bug and spent couple of hours
