Question

好吧所以我试图对Javascript对象或Javascript数组对象中的一些结果进行排序，但我似乎无法破解这一个，但我希望能够按不同的键排序值..

我尝试了什么（使用“金额”键）

（想象一下，可排序变量包含Javascript对象或Javascript对象数组）

var sortable;
            sortable.sort(function (a, b) {
                return a.amount > b.amount;
            });
console.log(sortable);

Javascript对象

"1": {
    "BTC": {
      "name": "Bitcoin",
      "symbol": "BTC",
      "amount": "5.0000000000",
      "rank": "1",
      "usd_coin": "3580.68",
      "btc_coin": "1.00",
      "volume": "1324380000.00",
      "marketcap": "59337865239.00",
      "1h": "1.62",
      "24h": "0.65",
      "7d": "-12.23"
    },
    "ETH": {
      "name": "Ethereum",
      "symbol": "ETH",
      "amount": "1153.0000000000",
      "rank": "2",
      "usd_coin": "247.05",
      "btc_coin": "0.07",
      "volume": "421132000.00",
      "marketcap": "23388713395.00",
      "1h": "2.06",
      "24h": "1.70",
      "7d": "-12.80"
    },
    "LTC": {
      "name": "Litecoin",
      "symbol": "LTC",
      "amount": "15.0000000000",
      "rank": "5",
      "usd_coin": "48.84",
      "btc_coin": "0.01",
      "volume": "276411000.00",
      "marketcap": "2587009816.00",
      "1h": "2.90",
      "24h": "1.84",
      "7d": "-20.80"
    }
  }

对象数组

[
  [
    {
      "name": "Bitcoin",

有关排序数组的信息，请参阅MDN: Array.prototype.sort()上的示例。 sort函数允许您将自己的自定义排序功能传递给它。

也可以使用地图功能。
