Javascript中的innerHTML和console.log的區別-有解無憂

我正在嘗試從本地 Json 獲取 API。我的 console.log 顯示了我真正想要的for loop. 但我的output.innerHTML不起作用。我首先嘗試使用我的<div></div>標簽，然后將其轉換為pre標簽。仍然不起作用。它只顯示一條線。我想念什么？

資料.json：

    "resultDescription": "success",
    "body": {
        "intraDayTradeHistoryList": [

                "quantity": 100
            },
]};

index.html（省略硬代碼）：

<body>
    <pre id="output"><br></pre>
    <script src="main.js"></script>
</body>

main.js 檔案：

const output = document.getElementById("output");

const jsonData = fetch("./data.json")
.then(res => res.json())
.then(data => {
    //const dataLen = data.body.intraDayTradeHistoryList.length;
    const tradeHist = () => 
    {
    for(let i = 0; i <= 5;i  ){
          output.innerHTML = (JSON.stringify(data.body.intraDayTradeHistoryList[i]));
          console.log(JSON.stringify(data.body.intraDayTradeHistoryList[i]));

    }
}
tradeHist();
})
.catch(error => console.log("Error"))

uj5u.com熱心網友回復：

正如我的評論中所解釋的，這是固定代碼：

const jsonData = fetch("./data.json")
.then(res => res.json())
.then(({body: {intraDayTradeHistoryList}}) => {
    let html = '';
    for (const entry of intraDayTradeHistoryList){
        html  = JSON.stringify(entry);
    }
    output.innerHTML = html;
})
.catch(error => console.log(error))
