scroll-into-view使用注意事项

1:不能写成死值
<scroll-view :scroll-into-view="scrollIntoView" scroll-with-animation class="index-container" scroll-y="true" @scroll="handleScroll">
2:且要变化,否则再次触发返回顶部的时候 会失效

        let scrollIntoView = ref('')  

    function handleScroll(event) {  

        scrollIntoView.value = ''  

    }  

    function backToTop() {  
        scrollIntoView.value = "top"  
    }
