vue设置overflow-y: auto;keepAlive滚动条位置不正确

可以尝试在keepAlive组件中添加一个ref属性，并在mounted生命周期中获取该组件的scrollTop属性，然后在activated生命周期中将scrollTop属性设置回去，以保持滚动条位置正确。具体代码如下：

<template>
<keep-alive ref="keepAlive">
<router-view></router-view>
</keep-alive>
</template>

<script>
export default {
mounted() {
this.scrollTop = this.$refs.keepAlive.$el.scrollTop;
},
activated() {
this.$refs.keepAlive.$el.scrollTop = this.scrollTop;
}
}
</script>
