JavaScript-将Date（）转换为秒 [英] JavaScript - Converting a Date() into seconds

问题描述

我正在使用Algolia的此处的Hacker News API：

I'm using the Hacker News API made at Algolia here:

https://hn.algolia.com/api

我有点困惑，因为它说从某个特定的日期开始搜索帖子它说运行以下查询的时间：

I'm a bit confused as it says to search for posts since a certain time it says to run the following query:

自时间戳记 X 后的注释（秒）
http://hn.algolia.com/api/v1/search_by_date?tags=comment&numericFilters=created_at_i>X

Comments since timestamp X (in second) http://hn.algolia.com/api/v1/search_by_date?tags=comment&numericFilters=created_at_i>X

它说以秒为单位的时间戳替换 X ，但是您将如何做到这一点呢？假设我最近发表的帖子是 2015-08-25T15：35：58.000Z 。自该日期以来，我将如何精确地运行此查询来搜索帖子？我不知道如何将此日期转换为秒...

It says to replace X with a timestamp in seconds, but how exactly would you do this? Let's say the last post I have is at 2015-08-25T15:35:58.000Z. How exactly would I run this query to search for posts since that date? I don't know how to convert this date to seconds...

预先感谢！

推荐答案

getTime（）将获取以毫秒为单位的日期，因此除以1000：

getTime() will get the date in milliseconds, so divide by 1000:

var date = new Date("2015-08-25T15:35:58.000Z");
var seconds = date.getTime() / 1000; //1440516958
