vue跳转页面返回后定位问题

1、给滚动元素添加ref标记

   <div ref="wrapper" }"><div>

2、监听滚动事件

  mounted() {
    this.$refs.wrapper.addEventListener('scroll', this.handelscroll)
  },

3、vuex保存元素滚动的位置scrollTop

export default new Vuex.Store({
  state: {
    scrollTop: 0,
  },
  mutations: {
    handleScroll(state, value) {
      state.scrollTop = value
    },
  },
  getters: {},
})

    handelscroll() {
      let scrollTop = this.$refs.wrapper.scrollTop
      this.$store.commit('handleScroll', scrollTop)
    },

4、返回时给滚动元素到指定位置

  activated() {
    this.$refs.wrapper.scrollTop = this.$store.state.scrollTop
  },
