我正在使用 primeNG p-Calendar Control 和 AutoComplete。这是我的代码（笨拙）（单击编辑然后保存“）我有两个问题：

  • 无论出于何种原因，我都无法获得新选择的日期。无论我做什么，我总是会得到旧日期。
  • 我需要能够检查自动完成或日历是否为空。如果有人为空，则应禁用“保存”按钮，并且跨度（必需）应出现在空白字段旁边

对于 pCalendar，删除[dataType]="date"然后它会在您点击保存时发送正确的日期。认为这是由于您的模型属性followupDate不是Date类型。

为了简单起见，验证几乎是您将如何进行任何其他验证的方式（不是 100% 有效，会影响其他行，但您明白了）：

isValid(row) {
   if (row.followupDate && this.bsaListVal) {
     return false;
   }
   return true;
 }

<button (click)="editRow(row)" [disabled]="isValid(row)">Save</button>

希望有帮助。
