javascript - 如何遍历 json 数组并使用 jQuery 提取值

Question

所以我在订单确认页面上显示了以下 JSON:

var orderDetails = {
    "orderID": "o32770183",
    "orderQty": 3,
    "orderTotal": 575.97,
    "orderShipping": 49.97,
    "orderDiscount": 0,
    "orderTax": 39.74,
    "orderCity": "Norwalk",
    "orderState": "Connecticut",
    "itemId": [
        "sku500134",
        "sku230312",
        "sku133846"
    ],
    "itemQty": [
        1,
        1,
        1
    ],
    "itemPrice": [
        159.99,
        225.99,
        189.99
    ],
    "itemName": [
        "The 'Inaugural' Raymond R Cabernet Sauvignon",
        "H de l'Hospitalet",
        "Chateau Florie Aude"
    ]
}

提取数据的最佳方法是什么？

Answer 1

或者，像这样 - 一种更动态的方法 - (如果你不知道对象元素)

for(i in orderDetails)
  alert(orderDetails[i])
