javascript - 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 元素中 API 的 JSON 值。我已经做好了将 JSON 数据读入对象并存储为变量等的所有工作，但我想知道如何以动态方式显示来自 JSON 对象的值。

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,

              },

我希望它以 HTML 2 不同的条目返回。但是，例如，如果此 API 调用要返回 5 个条目，我希望它以 HTML 格式返回 5 个不同的条目。处理此问题的最佳方法是什么？

Answer 1

您可以在 JSON 对象上循环，例如，创建表格行来显示结果。就像您的 JSON 对象名称是“结果”一样。您可以使用如下所示的 jquery 遍历“账单”。我刚刚添加了前 4 个元素。您可以根据您的 Json 对象添加尽可能多的内容。最后，“trHTML”可以作为表格添加到 HTML 页面。循环会动态迭代任意数量的账单，例如 4、5、100

$.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>';

        });
