如何排序Javascript對象或對象數組？

Question

好的，所以我試圖對保存在Javascript對象或Javascript對象數組中的某些結果進行排序，但是我似乎無法破解該結果，但是我希望能夠按不同鍵的值進行排序。

我嘗試了什么（使用鍵“金額”）

（想象一下sortable變量包含Javascript對象或Javascript對象數組）

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

Javascript對象

"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"
    }
  }

Answer 1

有關對數組進行排序，請參見MDN上的示例：Array.prototype.sort（） 。 sort函數使您可以將自己的自定義排序函數傳遞給它。

也可以使用地圖功能。
