      showProvince:false,  //展示省份
      showAlb:false,   //展示字母键盘
      whitchKey:0
    }
  },
  selectVisible: false,
}
export let computed = {
  plateNumber1 : {
    get () {
      return this.plateNumber||''
    },
    set (val) {
      this.$emit('update:plateNumber', val)
    }
  }
}

因为这里用了独家的框架，所以根据需要把相应的生命周期函数放到正常的vue项目的位置，把event就写成正常的函数，methods就是i正常的methods里面的方法，model就是data里return的数据
