你好，我来自 php 背景，并试图通过 Javascript/JQuery 对一些 JSON 数据进行分组。我想通过裁剪 SKU 并将我已成功完成的记录分组在一起来对数据进行分组，但是我无法将数据放入“子”部分，它似乎只循环第一条记录。理想情况下，子部分应包含 JSON 文件中的所有数据，但按父 SKU 对它们进行分组。
我尝试了以下方法:
var items = [
{
product_type: "configurable",
options: [
{
label: "Size",
value: "7.5",
option_id: 190,
option_value: 106
}
],
qty: 3,
item_id: "300",
product_id: "88105",
product_name: "MENS SHOE TUDOR BLACK",
product_sku: "M1S-TUD02-AVEL-79-7.5",
},
{
product_type: "configurable",
options: [
{
label: "Size",
value: "11",
option_id: 190,
option_value: 99
}
],
qty: 3,
item_id: "298",
product_id: "88105",
product_name: "MENS SHOE TUDOR BLACK",
product_sku: "M1S-TUD02-AVEL-79-11",
},
{
product_type: "configurable",
options: [
{
label: "Size",
value: "M",
option_id: 190,
option_value: 66
}
],
qty: 1,
item_id: "111",
product_id: "99945",
product_name: "WOMENS SWEATER",
product_sku: "W1R-613K-A10400-96-M",
},
{
product_type: "configurable",
options: [
{
label: "Size",
value: "L",
option_id: 190,
option_value: 12
}
],
qty: 20,
item_id: "278",
product_id: "99945",
product_name: "WOMENS SWEATER",
product_sku: "W1R-613K-A10400-96-L",
},
];
var groupedItems = {};
$.each(items, function(key, item) {
if (item.product_type === "configurable") {
var sku = item.product_sku,
parentSku = sku.replace(sku.substring(sku.lastIndexOf("-")), "");
if (sku.indexOf(parentSku) >= 0) {
groupedItems[parentSku] = {
product_sku: parentSku,
product_name: item.product_name,
product_type: item.product_type,
children: [item]
};
}
}
});
console.log(groupedItems);<!DOCTYPE html>

</html>我们非常欢迎任何帮助。我想要一个数组，它将数据分组到各自的组中，并从第一个记录中获得一些信息，例如名称、父级 sku 等，然后子部分具有项目的所有信息，但显然在各自的组中。希望这是有道理的!再次感谢!
最佳答案
您可以使用 reduce 按 product-sku 分组
var items = [{
product_type: "configurable",
options: [{
label: "Size",
value: "7.5",
option_id: 190,
option_value: 106
}],
qty: 3,
item_id: "300",
product_id: "88105",
product_name: "MENS SHOE TUDOR BLACK",
product_sku: "M1S-TUD02-AVEL-79-7.5",
},
{
product_type: "configurable",
options: [{
label: "Size",
value: "11",
option_id: 190,
option_value: 99
}],
qty: 3,
item_id: "298",
product_id: "88105",
product_name: "MENS SHOE TUDOR BLACK",
product_sku: "M1S-TUD02-AVEL-79-11",
},
{
product_type: "configurable",
options: [{
label: "Size",
value: "M",
option_id: 190,
option_value: 66
}],
qty: 1,
item_id: "111",
product_id: "99945",
product_name: "WOMENS SWEATER",
product_sku: "W1R-613K-A10400-96-M",
},
{
product_type: "configurable",
options: [{
label: "Size",
value: "L",
option_id: 190,
option_value: 12
}],
qty: 20,
item_id: "278",
product_id: "99945",
product_name: "WOMENS SWEATER",
product_sku: "W1R-613K-A10400-96-L",
},
];
var groupedItems = items.reduce((acc, item) => {
if (item.product_type === "configurable") {
var sku = item.product_sku;
var parentSku = sku.replace(sku.substring(sku.lastIndexOf("-")), "");
if (sku.indexOf(parentSku) >= 0) {
if (!!acc[parentSku]) {
let children = acc[parentSku].children;
acc[parentSku].children = [...children, { ...item
}];
} else {
acc[parentSku] = {
product_sku: parentSku,
product_name: item.product_name,
product_type: item.product_type,
children: [item]
};
}
}
}
return acc;
}, []);
