本文介绍使用APICloud AVM框架封装SKU（商品规格选择）组件，该SKU组件可实现商品图片与颜色属性进行联动，通过颜色、版本来控制价格，总价通过买入数量与所选商品价格进行自动计算；可进行缺货设定。
上述功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，需要通过函数进行判断，以保证在商品缺货的情况下，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];
//保证默认选中的商品是有货的
if(element.status){
this.data.selectGuige = element;
break;
}
}
}
},
