select a particular tuple in angular - html

Question

in my angular application i have a list of schedule objects in schedule array that are displayed using ngFor.
i want that whenever i click the checkbox on the left of my schedule box that particular schedule is selected as current schedule and rest is set to false .
i also want that my default selected schedule is the one that is most recently added to the array.
here is my HTML code
<div class="Box" *ngFor="let schedule of availableSchedules">
<div class="row width100">
<div class="col-md-1">
<div class="container">
<div class="round">
<input type="checkbox" id="checkbox" />
<label for="checkbox"></label>
</div>
</div>
</div>
<div class="col-md-11">
<div class="row width100" style="font-size: larger;">
<div class="col-md-4">
From : <span>{{schedule.startTime}}</span>
</div>
<div class="col-md-4">
To : <span>{{schedule.endTime}}</span>
</div>
<div class="col-md-2"></div>
</div>
<label for="days" style="font-size: larger;">Days</label>
<div class="row" name="days" style="margin-top: 5px;padding-left: 5px;">
<span class="chip" *ngFor="let day of schedule.days">{{day}}</span>
</div>
</div>
</div>
</div>
here is my ts code
currentSchedule = new tutorAvailablitySchedule();
availableSchedules: tutorAvailablitySchedule[] = [];
selectSchedule(schedule:tutorAvailablitySchedule) {
this.currentSchedule = schedule;
console.log(event);
}

Answer 1

That you should do the job:
<input type="checkbox"
[ngModel]="schedule===currentSchedule"
(ngModelChange)="selectSchedule($event ? schedule : null)" />
If you need to prevent an empty selection, you should use a radio button instead. In that case, you don't event need to define the selectSchedule function:
<input type="radio" name="schedule"
[value]="schedule"
[(ngModel)]="currentSchedule"/>
