如何在这个 JSON 中添加另一个“条目”？

Question

我下载了一些 JSON，如下所示。在开发者控制台中，它看起来像一个包含嵌套对象的对象，其中包含嵌套对象...

我想在数据中添加一个新的空“活动”（在前面）。我该怎么做？

插入

var blankCampaignData = {'title': '', 'description': '', 'path_to_logo': '', 'start_time': date, 'end_time' : date, 'paused': false};

进入

Answer 1

确定下一个广告系列 ID 应该是什么：

var nextId = +Object.keys(obj.campaigns).sort().pop() + 1;

将空广告系列添加到广告系列对象。显然你需要事先定义date。

obj.campaigns[nextId] = {
  'title': '',
  'description': '',
  'path_to_logo': '',
  'start_time': date,
  'end_time' : date,
  'paused': false
}
