javascript - 如何以编程方式向 JS 对象添加内容？

Question

我正在使用 Shopify，并且必须将 Qubit 添加到客户网站。

在任何给定时间，都有一个“购物篮”对象显示用户购物车中的产品。

如何动态地将对象插入到这个 json 结构中？

  "line_items": [{
      "product": {
        "id": "1234567890",
        "sku_code": "0987654321",
        "url": "product.html",
        "name": "Sparkly Shoes",
        "description": "Description about this product",
        "manufacturer": "The Shoe Co",
        "category": "Shoe",
        "subcategory": "Heels",
        "color": "n/a",
        "stock": 3,
        "size": "6",
        "currency": "GBP",
        "unit_price": 130,
        "unit_sale_price": 130,
        "voucher": "MYVOUCHER1"
      },
      "quantity": 1,
      "subtotal": 130,
      "total_discount": 0
    }, {
      "product": {
        "id": "1234567890",
        "sku_code": "0987654321",
        "url": "product-dress.html",
        "name": "Red Dress",
        "description": "Description about this product",
        "manufacturer": "The Dress Co",
        "category": "Dresses",
        "subcategory": "Red dresses",
        "color": "n/a",
        "stock": 3,
        "size": "6",
        "currency": "GBP",
        "unit_price": 200,
        "unit_sale_price": 150,
        "voucher": "MYVOUCHER1"
      },
      "quantity": 1,
      "subtotal": 200,
      "total_discount": 50
    }, {
      "product": {
        "id": "1234567890",
        "sku_code": "0987654321",
        "url": "product-swimwear.html",
        "name": "Bikini",
        "description": "Description about this product",
        "manufacturer": "The Bikini Co",
        "category": "Swimwear",
        "subcategory": "Bikini",
        "color": "n/a",
        "stock": 3,
        "size": "6",
        "currency": "GBP",
        "unit_price": 100,
        "unit_sale_price": 100,
        "voucher": "MYVOUCHER1"
      },
      "quantity": 1,
      "subtotal": 100,
      "total_discount": 0
    }]
  },

它可以是一种产品，也可以是两种产品等...我如何动态迭代购物车中的可用产品(伪代码很好)，然后显示一些值？

<小时/>

如果我定义上面的 json 结构，我将如何动态地执行它？只是在代码之间添加一个循环吗？ (感觉很脏？)

一旦您获得了数据 - 它应该相当简单(基于上述网站的数据)-

window.universal_variable["basket"]["line_items"].push(myProductObj);

myProductObj 将如下所示:

{
      "product": {
        "id": "1234567890",
        "sku_code": "0987654321",
        "url": "product.html",
        "name": "Sparkly Shoes",
        "description": "Description about this product",
        "manufacturer": "The Shoe Co",
        "category": "Shoe",
        "subcategory": "Heels",
        "color": "n/a",
        "stock": 3,
        "size": "6",
        "currency": "GBP",
        "unit_price": 130,
        "unit_sale_price": 130,
        "voucher": "MYVOUCHER1"
      },
      "quantity": 1,
      "subtotal": 130,
      "total_discount": 0
    }
