将外部 json 文件转换为 html table

Question

我正在尝试将外部 JSON 文件数据转换为 HTML table 但它没有显示任何内容。我正在控制台中获取所有数据，但不在 HTML table.

中

这是我的 JSON 文件。 results.json

                }
            }
]}}

此JSON文件是从亚马逊产品广告api生成的。

这是我的 JavaScript 文件 background.js

$(document).ready(function(){
$.getJSON("results.json", function(data){
    console.log(data);
    var products = '';
    $.each(data.Items, function(key,value){
        products +='<tr>';
        products +='<td>'+value.ASIN+'</td>';
        products +='<td>'+value.BrowseNodeInfo/BrowseNodes/0/SalesRank+'</td>';
        products +='<td><a href="'+value.DetailPageURL+'">'+value.ItemInfo/Title/DisplayValue+'</a></td>';
        products +='<td>'+value.Offers/Listings/0/Price/DisplayAmount+'</td>';
        products +='<td><img src="'+value.Images/Primary/Small/URL+'"></td>';
        products +='</tr>';
        $("#tablebody").append(products);
    });
});
});

我正在尝试仅将某些数据从 JSON 文件加载到 html table，例如销售排名、标题、ASIN 代码等，以及图像 link <img src=""> 标签和产品 url 在 <a href=""></a> 标签中，商品标题在 'a' 标签之间。

这是我的 HTML 代码的样子 popup.html

<body>
    <script src="jquery-3.4.1.min.js"></script>
    <script src="background.js"></script>
    <table id="jsontable">
        <thead>
            <tr>
            <th>ASIN</th>
            <th>Sales Rank</th>
            <th>Title</th>
            <th>Price</th>
            <th>Image</th>
            </tr>
        </thead>
        <tbody id="tablebody"></tbody>
    </table>
</body>

我被困在这里好几天了，请帮我完成这段代码。谢谢。

请尝试 this.You 需要存储响应然后获取主键。一旦你获取了所需数据的主节点，你就可以对其进行操作

Answer 2

我猜你访问数据的方式可能是错误的。

首先，使用data.SearchResult.Items访问项目替换，data.Items。

其次，value.BrowseNodeInfo/BrowseNodes/0/SalesRank不是JS语法访问对象。您可能希望将其更改为 value.BrowseNodeInfo.BrowseNodes[0].SalesRank，与代码中的其他位置相同。

让你的代码在这里工作：http://jsfiddle.net/thanhdx0/Lhvopz3a/

告诉我它是否有效。
