javascript - 过滤带有日期的对象数组

问题描述

我正在尝试从下面给出的满足以下两个条件的对象数组中获取数据并存储到 2 个单独的数组中

  1. 从当前的对象数组中，我只想获取月份为当前月份的对象。

  2. 过去 7 天的另一个数组

我该怎么办？我可以得到任何提示来处理日期，因为我不太擅长它吗？

解决方案

这里的Date对象会有很大帮助。要获得本月的订单，您可以尝试以下操作：

orders.filter(order => {
  const orderDate = new Date(order.orderDate);
  const today = new Date();
  const isThisYear = orderDate.getFullYear() === today.getFullYear()
  const isThisMonth = orderDate.getMonth() === today.getMonth();

  return isThisYear && isThisMonth;
})

要在最后 7 天获得，您可以尝试以下操作：

orders.filter(order => {
  const orderDate = Date.parse(order.orderDate); // in milliseconds
  const today = Date.now(); // in milliseconds
  const millisecondsInAWeek = 604800000;

  return orderDate > today - millisecondsInAWeek;
})
