Angular 9:当按下任意键时如何在mat-input中聚焦

Question

如何在键盘上按任意键的情况下，在mat输入中聚焦。

已经尝试过：

@HostListener('document:keydown', ['this.search.nativeElement.focus()'])

Answer 1

试试这个：

@HostListener('document:keypress', ['$event'])
    handleKeyboardEvent(event: KeyboardEvent) {
        this.search.nativeElement.focus();
    }

Answer 2

耶，修好了，谢谢

 @HostListener('document:keypress', ['$event'])
  handleKeyboardEvent(event: KeyboardEvent) {
    this.search.nativeElement.focus();
    this.searchFocus();
  }

  keyboardFocusOut() : void {
    this.searchText = ""
    this.search.nativeElement.blur();
    this.searchFocusOut();
  }
