关于前端:elcheckboxgroup获取多选框勾选最新值

      <el-form-item label="告诉形式：">
          <el-checkbox-group v-model="noticeWay" @change="noticeWayChange">
            <el-checkbox v-for="v in option" :key="v.id" :label="v.id"  >{{v.lable}}</el-checkbox>
          </el-checkbox-group>
        </el-form-item>

    noticeWayChange(val){
      console.log(val)
      let currval = val[val.length - 1];//以后扭转的选项

      if(currval == 3){
       ....
      }
    },
