Question

演示：https://stackblitz.com/edit/angular-bife8z-px13fl?file=app%2Fdatepicker-basic.html

我已经将Day(Sunday(添加为静态文本，我希望根据日历中的日期选择进行更改。

Answer 1

您可以使用日历来获取一周中的哪一天，并拥有一个存储日期名称的Dictionary。

weekDays = {
1: 'Monday',
2: 'Tuesday',
3: 'Wednesday',
4: 'Thursday',
5: 'Friday',
6: 'Satarday',
7: 'Sunday'
}
Selected Date is: <b>{{weekDays[calendar.getWeekday(model)]}}

事实上，您可以在model变量的setter中设置一个day变量。

selectedDay: string = '';
set model(val) {
this._model = val;
this.selectedDay = this.weekDays[this.calendar.getWeekday(this.model)]
}
get model() {
return this._model;
}
Selected Date is: <b>{{selectedDay}}</b> <br>

Answer 2

试试这个：

组件html

Selected Date is: <b>{{getDay(model)}}</b>

组件ts

getDay(model){
let date = new Date(Date.UTC(model.year, model.month - 1, model.day, 0, 0, 0))
let days = new Array( "Monday", "Tuesday", "Wednesday", "Thursday",  "Friday", "Saturday", "Sunday" );
let day = days[date.getDay() - 1]
return day
}
