//置顶    async stickHonor(index) {    //index为数据当前下标      let obj = this.honorList[index];      const id = obj.id;      obj.isStick = 1;      console.log(id);      const isStick = 1;   //置顶状态      const res = await stickStudentHonors({ id,isStick });  //调用接口改变数据状态      //删除之前的位置的数据      this.honorList.splice(index, 1);      //在数组下标为0插入数据,每次置顶数据都是在最前面      this.honorList.splice(0, 0, obj);    },    //取消置顶    async unstickHonor(index) {   //index为数据当前下标      let sum = 0;      for (let data of this.honorList) {        if (data.isStick == 1) {          sum++;        }      }      let obj = this.honorList[index];      const id = obj.id;      const isStick = 0;    //为不置顶      const res = await stickStudentHonors({ id,isStick });    //调用接口改变数据的状态      obj.isStick = 0;      //删除之前的位置的数据      this.honorList.splice(index, 1);      //置顶数据下面插入数据,因为sum把之前自己置顶的也算进去,所以sum-1      this.honorList.splice(sum-1, 0, obj);    }

   因为splice()方法为vue数组的响应式方法,所以会自动刷新数据
