javascript - Angular 2 : generating checkboxes issue

Question

我有以下模板:

<div *ngFor="#weekday of weekdays" class="checkbox">
    <label>
        <input
            #{{weekday}}
            (change)="selectWeekday('{{weekday}}', {{weekday}}.checked)"
            type="checkbox"> {{weekday}}
    </label>
</div>

由该组件支持:

@Component({
    selector: "schedule",
    templateUrl: "app/schedule.html",
})
export class ScheduleComponent {
    public weekdays: string[] = [ "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" ];

    public selectWeekday(weekday: string, checked: boolean {
        // ...
    }
}

我收到以下错误:

Got interpolation ({{}}) where expression was expected at column 15 in [selectWeekday('{{weekday}}', {{weekday}}.checked)]

我做错了什么？

尝试这种方法:

<div *ngFor="#weekday of weekdays" class="checkbox">
<label>
    <input
        (change)="selectWeekday(weekday, $event.target.checked)"
        type="checkbox"> {{weekday}}
</label>
</div>
