AVM（Application-View-Model）前端组件化开发模式基于规范Web Components组件化思维，提供蕴含虚构DOM和Runtime的编程框架avm.js以及多端对立编译工具，齐全兼容Web Components规范，同时兼容Vue和React语法糖编写代码，编译工具将Vue和React相干语法糖编译转换为avm.js代码。
基于规范 Web Components 组件化思维，兼容 Vue / React 语法个性，通过一次编码，别离编译为 App、小程序代码，实现多端开发。
组件性能介绍
封装了车牌号输出键盘，反对燃油汽车、新能源车辆、教练车、挂车、警车5种模式。针对输出的车牌号进行了正则验证。
如有其余类型的车牌须要输出，可在此基础上进行增加即可，次要是管制号牌长度和一些固定的字。

组件应用阐明
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 , 具体反对状况还要看每个组件的阐明文档。
首先须要登录开发平台，http://www.apicloud.com。 通过管制平台右上方的模块Store进入，而后抉择AVM组件。
找到对应模块进入，也可通过搜寻栏，通过组件名称关键字进行检索。
进入模块详情，点击立刻下载下载残缺的组件安装包。
组件压缩包的文件目录如下
也可通过查看模块文档 来理解模块的具体参数，援用的原生模块，注意事项等。
具体在我的项目中的应用步骤是，第一步将压缩文件中的car-num-keyboard.stml文件拷贝到我的项目的components目录，通过浏览readme.md 文档和查看demo示例文件 demo-car-num-keyboard.stml在须要开发的stml文件中，引入组件文件，实现页面的开发。
在调用键盘的时候，是通过v-if 进行键盘的显示和暗藏，v-if false的状况会销毁元素，所以须要传递的动静值，必须要在元素从新创立之前进行赋值操作。如下图所示，先后顺序很重要。

如果在AVM组件库中，没有找到理论我的项目中须要的组件，能够本人尝试封装组件。
