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
该 SKU 组件可实现商品图片与色彩属性进行联动，通过色彩、版本来管制价格，总价通过购买数量与所选商品价格进行主动计算；可进行缺货设定。
上述性能点是通过商品数据结构和代码逻辑进行配合来实现的。
商品数据结构如下：

]每个商品的版本有多条数据，每条数据都对应不同的价格，同时会有字段标识是否有货。
每一个商品也会有字段标识是否有货。
当切换商品属性时，须要通过函数进行判断，以保障在商品缺货的状况下，不能被选中。
setGoods(e){
// console.log(JSON.stringify(e));
let item = e.currentTarget.dataset.item;
if(item.status){
this.data.selectGoods = item;
this.data.guigeList = item.guige;
for (let index = 0; index < item.guige.length; index++) {const element = item.guige[index];
// 保障默认选中的商品是有货的
if(element.status){
this.data.selectGuige = element;
break;
}
}
}},

</style>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 easy-sku.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-easy-sku.stml 在须要开发的 stml 文件中，引入组件文件，实现页面的开发。
