Question

我有一个对象数组，格式如下：

var res = [
  { StartTime: "04/29/2020 13:30", Status: "free" },
  { StartTime: "04/29/2020 14:00", Status: "free" },
  { StartTime: "04/29/2020 14:30", Status: "free" },
  { StartTime: "04/29/2020 15:00", Status: "free" },
  { StartTime: "04/29/2020 20:00", Status: "free" },
  { StartTime: "04/29/2020 20:30", Status: "free" },
];

现在，我想创建一个对象，将该对象数组拆分为2个对象数组，如果StartTimes相差30分钟，它们可以保持在一起，否则，我将继续创建一个新数组，该对象看起来像这样：

var res = [
  [
    { StartTime: "04/29/2020 13:30", Status: "free" },
    { StartTime: "04/29/2020 14:00", Status: "free" },
    { StartTime: "04/29/2020 14:30", Status: "free" },
    { StartTime: "04/29/2020 15:00", Status: "free" },
  ],
  [
    { StartTime: "04/29/2020 20:00", Status: "free" },
    { StartTime: "04/29/2020 20:30", Status: "free" },
  ],
];

我正在使用moment.js查找两个日期之间的差异。

您可以使用原始JavaScript来完成此操作，例如：

var res = [
  { StartTime: "04/29/2020 13:30", Status: "free" },
  { StartTime: "04/29/2020 14:00", Status: "free" },
  { StartTime: "04/29/2020 14:30", Status: "free" },
  { StartTime: "04/29/2020 15:00", Status: "free" },
  { StartTime: "04/29/2020 20:00", Status: "free" },
  { StartTime: "04/29/2020 20:30", Status: "free" },
];

let j = 0, result = [], previous;
for (let i = 0; i < res.length; i++) {
  let current = new Date(res[i].StartTime);
  if (previous && current.getTime() - previous.getTime() > 30 * 60 * 1000) j++;
  (result[j] = result[j] || []).push(res[i]);
  previous = current;
}

console.log(result);

lodash比较数组中的对象，并根据此比较创建新对象
