角度9:当按键按下任意键时，如何在垫子输入中聚焦

Question

当按键按下键盘上的任何键时，如何在垫子输入中集中注意力。

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

YAY修复了它并感谢

 @HostListener('document:keypress', ['$event'])
  handleKeyboardEvent(event: KeyboardEvent) {
    this.search.nativeElement.focus();
    this.searchFocus();
  }
  keyboardFocusOut() : void {
    this.searchText = ""
    this.search.nativeElement.blur();
    this.searchFocusOut();
  }
