当使用JSON数据填充数组时遇到不一致的情况，会在控制台中显示一个空数组。-PHP中文网问答

我正在尝试使用AlphaVantage API获取一些数据，并且我想将某只股票支付的所有股息存储在一个数组中。我现在只尝试保存股息，但将来我希望能将股息与特定日期关联起来。

用于检索数据的函数：

async function fetchTimeSeriesDailyAdjusted (ticker) {  //Fetch function to get the daily close and the dividends
    const apiTimeSeriesDailyAdjusted = `https://www.alphavantage.co/query?function=TIME_SERIES_DAILY_ADJUSTED&symbol=${symbol}&apikey=${apiKey}`; //Lik of the API - update the symbol

    try {
        const response = await fetch(apiTimeSeriesDailyAdjusted);
        const data = await response.json(); 
        const historicalDividend = []; //Array of the dividends
        
        for (let date in data['Time Series (Daily)']) { //This for should make the code go through all the JSON
            historicalDividend = entry ['7. dividend amount']; //This should store the dividend while the for loop "goes"
        }

        console.log(historicalDividend); //Console log to see the dividend

        return historicalDividend; //Value that the function must return
    } catch (error) {
        console.error('Error fetching apiTimeSeriesDailyAdjusted'); //Log of the error
    }
}

这是我创建的函数，但正如我所看到的，可能你也看到了，它不起作用。
