Unable to connect information to list item

I'm struggling to figure out why I am unable to bind this data into the li element. When I check the console, I can see the data under calendar.Days and within that are the individual day values. Any assistance would be highly appreciated.

Code

@Component({
    selector: "calendarPopoverInternal",
    template:   `<div class="schedule-calendar-container">                            
                    <div class="schedule-calendar-week-container">
                         <ul class="selectable ui-selectable">
                            <li class="ui-state-default schedule-calendar-day"
                                *ngFor="let day of calendar.Days; let i = index;"
                                [ngClass]="getDaySelectionClass(day)"
                                [day]="day"
                                [index]="(i + j)"
                                (onkeydown)="onDayKeyPress($event, day)"
                                [attr.data-day]="day">
                            </li>
                        </ul>
                    </div>
                </div>`

})

Error

Can't bind to 'day' since it isn't a known property of 'li'. ("                      [ngClass]="getDaySelectionClass(day)"
                                        [ERROR ->][day]="day"
                                        [index]="(i + j)"
                               "): CalendarWeeks@6:40

Answer №1

When attempting to bind [day]="day" to a native <li> element, the compiler alerts you that this may be an error. This is because list elements do not possess such a property and therefore cannot utilize that value.

It appears as though what you intended was to establish a distinct component (such as <ListItem />) with a declared day property, which would have a <li> element at its core template. This approach would prove successful.

Answer №2

Modify the iterator variable from day to a different name and set it as [day].

example:

From

*ngFor="let day of calendar.Days; let i = index;"

To

*ngFor="let dayValue of calendar.Days; let i = index;"

and assign it as

[day]="dayValue"

If that doesn't work, then try

[attr.day]="dayValue"
