我正在尝试使用$refs. topScroll. scrollTo滚动到顶部按钮。当显示搜索列表并滚动到底部时,单击顶部按钮视图不会移动到块的顶部,显示无法读取未定义的属性(阅读“scrollTo”)错误。我正在尝试使用Alpinejs进行此操作,但我认为Vuejs也是如此。

您使用的$refs.topScroll可能无法正常工作,因此最好使用window.scrollTo

<div class="btn--content" x-data @click="window.scrollTo({top: 0, behavior: 'smooth'})">
   <span class="font--m1 text-underline">to top</span>
</div>
