我想写一个 JavaScript 函数,它在浏览器开发工具控制台中输出项目总数,每个项目的价格以及购物车的总价值。例如:需要选择Apple Iphone 5S及其价格,Solio Mono太阳能充电器及其价格等。不使用 硬编码密钥 (例如“Apple iPhone 5S”,“Solio Mono Solar Charger”)。有什么办法吗?
是否可以使用这种格式?
Items: 3
- Apple iPhone 5S ($299.99)
- Solio Mono Solar Charger ($29.95)
- 24 Month Warranty Package ($129.95)
Total: 459.89

var str = `Items: ${cart.Items} `;
Object.keys(cart.Item).forEach((key) => {
str += `- ${key} (${cart.Item[key].price}) `
})
str += `Total: ${cart.Total}`
console.log(str)

你可以遍历它们并抓住想要的数据。
您可以根据需要对其进行编辑。
cart = {
"Items": 3,
"Item": {
"Apple iPhone 5S": {
"productId": 688,
"url": "http://website.com/phone_iphone5s.html",
"price": 299.99
},
"Solio Mono Solar Charger": {
"productId": 655,
"url": "http://website.com/solio_charger.html",
"price": 29.95
},
"24 Month Warranty Package": {
"productId": 681,
"url": "http://website.com/24_month_warranty.html",
"price": 129.95
}
},
"Total": 459.89
}
for (var key in cart.Item) {
if (cart.Item.hasOwnProperty(key)) {
console.log(key + " " + cart.Item[key]);
}
}
