如何使用 PrimeNG 日历设置日历？

Question

我有一个日历控件，我想为它设置一些值，但我在下面的行中收到以下错误，而且值也没有设置。

this.data.dateIn = this.selecteddata.dateIn;

<p-calendar [(ngModel)]="data.dateIn" [showIcon]="true" name="dateInCalendar"   
             required #dateInCalendar="ngModel">
</p-calendar>

Answer 1

TypeError: date.getMonth is not a function

=> 我认为您正在使用该函数从日期中获取月份。但日期无效或格式错误。这就是为什么你的格式功能不起作用。

根据我的想法，请先使用moment.js来包装您的日期。示例：

let selectedDate = moment(dateString);

如果你想得到月份，你只需使用：

let month = ("0"+(selectedEndDate.get("month")+1)).slice(-2);

您的日期格式对 p-calendar 无效。您可以使用并将其传递给日历：

this.currentDate = moment(new Date()).format('YYYY-MM-DD');

Answer 2

问题已解决，为帮助他人提供解决方案，只需将 selecteddata.dateIn 转换为 .toDate()。

this.data.dateIn = this.selecteddata.dateIn.toDate();
