从本地存储中获取数据

Question

我的本地存储中有以下数据：

[{
  "event": "addToCart",
  "eventLabel": "Test Product",
  "ecommerce": {
    "currencyCode": "USD",
    "add": {
      "products": [{
        "name": "Test Product",
        "id": "78789",
        "price": "429.00",
        "category": "Catalog Page",
        "list": "Massage\/Massage Chairs\/Portable Massage Chairs",
        "quantity": "1"
      }]
    }
  }
}]

我需要获得ecommerce的价值。 于是得到以下数据：

"ecommerce": {
  "currencyCode": "USD",
  "add": {
    "products": [{
      "name": "Test Product",
      "id": "78789",
      "price": "429.00",
      "category": "Catalog Page",
      "list": "Massage\/Massage Chairs\/Portable Massage Chairs",
      "quantity": "1"
    }]
  }
}

我该怎么做？

var data = JSON.parse(json);

然后您可以访问任何数据键和值，如下所示：

var ecom = data.ecommerce
