我有下面的 json 数据。如何选择2020-11-06 19:50:00 的open 值并使用console.log() 将其记录到控制台？

{
    "Meta Data": {
        "1. Information": "Intraday (5min) open, high, low, close prices and volume",
        "2. Symbol": "IBM",
        "3. Last Refreshed": "2020-11-06 20:00:00",
        "4. Interval": "5min",
        "5. Output Size": "Compact",
        "6. Time Zone": "US/Eastern"
    },
    "Time Series (5min)": {
        "2020-11-06 20:00:00": {
            "1. open": "114.4400",
            "2. high": "114.4400",
            "3. low": "114.4400",
            "4. close": "114.4400",
            "5. volume": "457"
        },
        "2020-11-06 19:50:00": {
            "1. open": "114.4000",
            "2. high": "114.4000",
            "3. low": "114.3300",
            "4. close": "114.3300",
            "5. volume": "648"
        }
    }
}

你首先需要将它分配给一个变量，然后你应该能够像下面这样访问

var jsonData = {
    "Meta Data": {
        "1. Information": "Intraday (5min) open, high, low, close prices and volume",
        "2. Symbol": "IBM",
        "3. Last Refreshed": "2020-11-06 20:00:00",
        "4. Interval": "5min",
        "5. Output Size": "Compact",
        "6. Time Zone": "US/Eastern"
    },
    "Time Series (5min)": {
        "2020-11-06 20:00:00": {
            "1. open": "114.4400",
            "2. high": "114.4400",
            "3. low": "114.4400",
            "4. close": "114.4400",
            "5. volume": "457"
        },
        "2020-11-06 19:50:00": {
            "1. open": "114.4000",
            "2. high": "114.4000",
            "3. low": "114.3300",
            "4. close": "114.3300",
            "5. volume": "648"
        }
    }
};

console.log(jsonData["Time Series (5min)"]["2020-11-06 20:00:00"]["1. open"]);
