vue 移动端记录页面浏览位置的方法

//state中定义数据
 state: {
  carrerTouScroll: {
   height: '' //滚动的距离
   }
  }
 
 
 //mutations 操作state数据
 mutations: {
  setCarrerTouScroll (state, disdance) { //管理赛事 滚动距离
   state.carrerTouScroll.height = disdance
  },
 }
 
 
 //使用getters 有的不加这句也可以，但是有时候不加就不行，所以还是加上吧
  getters: {
   getCarrerTou: state => state.carrerTouScroll 
   }
