javascript - 如何检索只有 00:00:00 时间的数据？
问题描述
我想用 React 建立一个天气预报网站。我使用 openweather API。对于 5 天预报功能，openweath 每 3 小时更新一次数据。如果我想每天显示天气信息（绝对直到 5 天后），如果我想在 JavaScript 中只抓取 00:00:00 时间的数据，如何过滤数据？我不想一直显示它。
示例我想要什么（2021-06-07 00:00:00、2021-06-08 00:00:00 等...）
以下是 API 的响应。

解决方案
假设data是你的 JS 对象
let filtered = [];
for (var row of data.list) {
if (row.dt_txt.endsWith('00:00:00')) {
filtered.push(row)
}
}
这将创建一个新数组，遍历您的值列表，如果dt_text以 00:00:00 结尾，则当前行将添加到您的filtered数组中
