AVM（Application-View-Model）前端组件化开发模式基于标准Web Components组件化思想，提供包含虚拟DOM和Runtime的编程框架avm.js以及多端统一编译工具，完全兼容Web Components标准，同时兼容Vue和React语法糖编写代码，编译工具将Vue和React相关语法糖编译转换为avm.js代码。
基于标准 Web Components 组件化思想，兼容 Vue / React 语法特性，通过一次编码，分别编译为 App、小程序代码，实现多端开发。
组件功能介绍
封装了车牌号输入键盘，支持燃油汽车、新能源车辆、教练车、挂车、警车5种模式。针对输入的车牌号进行了正则验证。
如有其他类型的车牌需要输入，可在此基础上进行添加即可，主要是控制号牌长度和一些固定的字。

style>组件使用说明
本组件是基于AVM.js开发的多端组件，通常同时适配Android、iOS、小程序、H5 , 具体支持情况还要看每个组件的说明文档。
首先需要登录开发平台，http://www.apicloud.com。 通过控制平台右上方的模块Store进入，然后选择AVM组件。
找到对应模块进入，也可通过搜索栏，通过组件名称关键字进行检索。
进入模块详情，点击立即下载下载完整的组件安装包。
组件压缩包的文件目录如下
也可通过查看模块文档 来了解模块的具体参数，引用的原生模块，注意事项等。
具体在项目中的使用步骤是，第一步将压缩文件中的car-num-keyboard.stml文件拷贝到项目的components目录，通过阅读readme.md 文档和查看demo示例文件 demo-car-num-keyboard.stml在需要开发的stml文件中，引入组件文件，完成页面的开发。
在调用键盘的时候，是通过v-if 进行键盘的显示和隐藏，v-if false的情况会销毁元素，所以需要传递的动态值，必须要在元素重新创建之前进行赋值操作。如下图所示，先后顺序很重要。
