export default {
|
||||
data() {
|
||||
return {
|

showCustomAction: false,
|
||||
sku: data.sku,

Vue.component(Sku.name, Sku);
|
||||
```
|
||||

||||
买买买
|

### 数据结构
|
||||
#### sku对象结构
|
||||
```javascript
|
||||
"sku": {
|
||||
// 所有sku规格类目与其值的从属关系，比如商品有颜色和尺码两大类规格，颜色下面又有红色和蓝色两个规格值。
|
||||
// 可以理解为一个商品可以有多个规格类目，一个规格类目下可以有多个规格值。
|
||||
"tree": [{
|
||||
"k": "颜色", // skuKeyName：规格类目名称
|
||||
"v": [{
|
||||
"id": "30349", // skuValueId：规格值id
|
||||
"name": "红色", // skuValueName：规格值名称
|
||||
"imgUrl": "upload_files\/2017\/02\/21\/FjKTOxjVgnUuPmHJRdunvYky9OHP.jpg" // 规格类目图片，暂时只能第一个规格类目可以定义图片
|
||||
}, {
|
||||
"id": "1215",
|
||||
"name": "蓝色",
|
||||
"imgUrl": "upload_files\/2017\/03\/16\/Fs_OMbSFPa183sBwvG_94llUYiLa.jpeg"
|
||||
}],
|
||||
"k_s": "s1" // skuKeyStr：sku组合列表（下方list）中当前类目对应的key值，value值会是从属于当前类目的一个规格值id
|
||||
}, ...],
|
||||
// 所有sku的组合列表，比如红色、M码为一个sku组合，红色、S码为另一个组合
|
||||
"list": [{
|
||||
"id": 2259, // skuId，下单时后端需要
|
||||
"price": 100, // 价格（单位分）
|
||||
"s1": "1215", // 规格类目k_s为s1的对应规格值id
|
||||
"s2": "1193", // 规格类目k_s为s2的对应规格值id
|
||||
"s3": "0", // 最多包含3个规格值，为0表示不存在该规格
|
||||
"stock_num": 110 // 当前sku组合对应的库存
|
||||
}, ...],
|
||||
"price": "1.00", // 默认价格（单位元）后端单位暂时有点不统一
|
||||
"stock_num": 227, // 商品总库存
|
||||
"collection_id": 2261, // 无规格商品skuId取collection_id，否则取所选sku组合对应的id
|
||||
"none_sku": false, // 是否无规格商品
|
||||
"messages": [{ // 商品留言
|
||||
"datetime": "0", // 留言类型为time时，是否含日期。“1”表示包含
|
||||
"multiple": "0", // 留言类型为text时，是否多行文本。“1”表示多行
|
||||
"name": "留言", // 留言名称
|
||||
"type": "text", // 留言类型，可选id_no（身份证）, text, tel, date, time, email
|
||||
"required": "1" // 是否必填 “1”表示必填
|
||||
}, ...],
|
||||
"hide_stock": false // 是否隐藏剩余库存
|
||||
},
|
||||
```
|
||||
|
||||
#### goods对象结构
|
||||
```javascript
|
||||
"goods": {
|
||||
// 商品标题
|
||||
"title": "测试商品",
|
||||
// 默认商品sku缩略图
|
||||
"picture": "https:\/\/img.yzcdn.cn\/upload_files\/2017\/03\/16\/Fs_OMbSFPa183sBwvG_94llUYiLa.jpeg?imageView2\/2\/w\/100\/h\/100\/q\/75\/format\/webp"
|
||||
},
|
||||
```
|
||||
|
||||
#### 添加购物车和点击购买回调函数接收的skuData对象结构
|
||||
```javascript
|
||||
skuData: {
|
||||
// 商品id
|
||||
goodsId:"946755",
|
||||
// 留言信息
|
||||
messages: {
|
||||
message_0:"12",
|
||||
message_1:"",
|
||||
... // 有几个留言就有几条
|
||||
},
|
||||
// 选择的商品数量
|
||||
selectedNum:1,
|
||||
// 选择的sku组合
|
||||
selectedSkuComb: {
|
||||
id:2257,
|
||||
price:100,
|
||||
s1:"30349",
|
||||
s2:"1193",
