event事件：

methods方法：

model数据：

export let props = ['name','plateNumber','noRightPart']
export let model = {

        p4:2,
        p5:2,
        p6:2,
        p7:2,
        p8:0

  Keyboard: {
    province: ['京', '津', '冀', '晋', '蒙', '辽', '吉', '黑', '沪', '苏', '浙', '皖', '闽', '赣', '鲁', '豫', '鄂', '湘', '粤', '桂', '琼', '渝', '川', '贵', '云', '藏', '陕', '甘', '青','宁','新','台','港','澳','使','领','警','学'],
    number: ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C','D', 'E', 'F', 'G','H', 'J', 'K', 'L', 'M', 'N', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', '学', '港', '澳']
  },
}
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
