JavaScript - Converting a Date() into seconds
提问by germainelol
I'm using the Hacker News API made at Algolia here:
我在这里使用 Algolia 制作的 Hacker News API：
I'm a bit confused as it says to search for posts since a certain time it says to run the following query:
我有点困惑，因为它说要搜索帖子，因为它说要运行以下查询：
Comments since timestamp X(in second)
http://hn.algolia.com/api/v1/search_by_date?tags=comment&numericFilters=created_at_i>X
自时间戳记起的评论X（以秒为单位）
http://hn.algolia.com/api/v1/search_by_date?tags=comment&numericFilters=created_at_i>X
It says to replace Xwith 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...
它说要X以秒为单位替换时间戳，但是您究竟会如何做到这一点？假设我的最后一个帖子是在2015-08-25T15:35:58.000Z. 我将如何运行此查询来搜索自该日期以来的帖子？我不知道如何将此日期转换为秒...
Thanks in advance!
提前致谢！

getTime()will get the date in milliseconds, so divide by 1000:
getTime()将获得以毫秒为单位的日期，因此除以 1000：
var date = new Date("2015-08-25T15:35:58.000Z");
var seconds = date.getTime() / 1000; //1440516958
