在 Django 中显示来自 API 的 JSON 数据

Question

我正在寻找一种简单的方法来显示来自 Django 项目中的 API 的 JSON 值。 I've got everything working to read the JSON data into an object and store as variables, etc. but I am wondering how to make a dynamic way to display the values from the JSON Object.

比如说 JSON 看起来像这样

{
   "status":"OK",
   "copyright":"Copyright (c) 2017 Pro Publica Inc. All Rights Reserved.",
   "results":[
      {
         "num_results": 10,

我希望它在 HTML 2 个不同的条目中返回。 但是例如，如果这个 API 调用要返回 5 个条目，我希望它在 HTML 中返回 5 个不同的条目。 处理这个问题的最佳方法是什么？

Answer 1

您可以在 JSON object 上循环，例如，创建表行以显示结果。 就像您 JSON object 名称是“结果”一样。 您可以使用 jquery 来遍历“账单”，如下所示。 我刚刚添加了前 4 个元素。 您可以根据您的 Json object 添加任意数量。 最后“trHTML”可以作为表格添加到 HTML 页面。 循环将迭代任意数量的账单，例如 4、5、100 动态

$.each(data['bills'] , function (index, item) {
          trHTML += '<tbody><tr><td>'+item[0]+'</td><td>'+item[1]+'</td><td>'+item[2]+
          '</td><td>'+item[3]+'</td></tr></tbody>';

        });
