html - fromEvent 返回属性在类型 'Event' 上不存在

Question

我正在尝试根据光标的位置更改元素的位置。因此我有以下代码:

this.ngZone.runOutsideAngular(() => {
   fromEvent(window, 'mousemove').pipe(
     filter(() => this.hoveredCart !== -1),
   ).subscribe(({clientY}) => this.floatingElements.toArray()[this.hoveredCart].nativeElement
     .style.top = clientY);
});

它以某种方式返回错误:

Property 'clientY' does not exist on type 'Event'

Answer 1

fromEvent 使用通用类型，因此您可以告诉 TypeScript 它应该期望什么类型:

fromEvent<MouseEvent>(window, 'mousemove').pipe(
     filter(() => this.hoveredCart !== -1),
   ).subscribe(({clientY}) => this.floatingElements.toArray()[this.hoveredCart].nativeElement
     .style.top = clientY);
