我在这里使用的是Ionic 5，我注意到，当我在离子幻灯片1的幻灯片列表中有许多项目，而在下一张离子幻灯片中有一些项目时，当我以编程方式在两者之间切换时，项目较少的幻灯片开始低于它所包含的实际内容。
这就像幻灯片在转换过程中共享一个Y轴滚动位置。
幻灯片，其中两个，填充了一些嵌套在离子列表中的离子项(和滑动项)，它们被"滑动";通过与离子段按钮的相互作用。
是否有一种方法可以快速滚动到下一张幻灯片的顶部，这样在过渡期间就不会被注意到，或者，我需要添加一些其他代码来阻止幻灯片2从幻灯片1从…过渡的Y点开始
编辑:正在运行的代码的github repo，滚动到长列表的底部，然后单击Group2，下一张幻灯片从与上一张相同的Y点开始。

我需要添加这些位…
import { IonContent } from '@ionic/angular';
@ViewChild(IonContent) content: IonContent;
并将函数更改为
changeSegment(ev: any) {
this.view = this.sliderindex.indexOf(ev.detail.value);
this.slider.slideTo(this.view,250).then(()=>{
this.content.scrollToTop(0)
});
}
