使用ng-model将焦点设置为输入

Question

我有这个输入字段：

<input
  class="form-control"
  [(ngModel)]="event.name"
  name="name"
  required>

这个验证检查：

public isEventValid(Event: Event): boolean {
    if (Event.name.length == 0) {
        this.msgs = [{severity: 'error', summary: '', detail: 'Er is geen Eventnaam ingevuld'}];
        return false;
    }
    if (Event.name.trim().length == 0) {
        this.msgs = [{severity: 'error', summary: '', detail: 'De naam mag niet alleen uit spaties bestaan'}];
        return false;
    }
    if (Event.languageId == 0) {
        this.msgs = [{severity: 'error', summary: '', detail: 'Er dient een taal te worden gekozen'}];
        return false;
    }
    return true;
}

如果在验证检查中其中一个if语句为false，我如何在输入字段上设置光标？
