vue组件中scrollTop赋值无效啊，已经试了好多方法

Question

.vue

   mounted(){
        this.scrollToBottom()
    },
    methods:{
        scrollToBottom: function () {
            this.$nextTick(() => {
                var container = this.$el.querySelector('.chatContent');
                container.scrollTop = container.scrollHeight;
            })
        }
    },
    updated:function () {
        this.scrollToBottom();
    }
    

就想让div滚动条始终在底部，咋就这么难。。。
补充：目前调试的是针对响应式的时候，div高度拉长，滚动条居底部

Answer 1

container.scrollTo = container.scrollHeight;

Answer 2

updated () {
    this.$nextTick(function () {
        container.scrollTop = container.scrollHeight;
    });
},
