Js implementation time shows a collection of methods several days ago, several hours ago, or a few minutes ago, js a few days ago

Here we summarize common methods for displaying the js implementation time several days ago, several hours ago, or several minutes ago. Share it with you for your reference. The details are as follows:

Method 1:

My personal practice is to save the timestamp and then use the jq plug-in the front end for conversion, such as smart-time-ago.

Method 2:

(Via freemarker template) If you use freemarker template, you can write it like this, other templates, and so on.
Modify the conditions and output as needed, and pass your datetime in.

<# Macro timeline_dt datetime =. now> <# assign ct = (. now? Long-datetime? Long)/1000> <# if ct gte 31104000> <# -- n years ago -- >$ {(ct/31104000 )? Int} years ago <# t> <# elseif ct gte 2592000> <# -- n months ago -- >$ {(ct/2592000 )? Int} months ago <# t> <# elseif ct gte 86400*2> <# -- n days ago -- >$ {(ct/86400 )? Int} days ago <# t> <# elseif ct gte 86400> <# -- 1 day ago --> yesterday <# t> <# elseif ct gte 3600> <# -- n hours before --> ${(ct/3600 )? Int} hours ago <# t> <# elseif ct gte 60> <# -- n minutes ago -- >$ {(ct/60 )? Int} minutes ago <# t> <# elseif ct gt 0> <# -- n seconds ago -- >$ {ct? Int} seconds ago <# t> <# else> just </# if> </# macro>

Method 3:

Find a special plug-in PrettyTime

public static void main(String[] args) {     PrettyTime p = new PrettyTime();     System.out.println(p.format(DateUtils.addDays(new Date(), 2)));} 

Method 4:

Custom Java method:

Private final static long minute = 60*1000; // private final static long hour = 60 * minute in 1 minute; // private final static long day = 24 * hour in 1 hour; // One day private final static long month = 31 * day; // month private final static long year = 12 * month; // year/**** return the date of the text description ** @ param Date * @ return */public static String getTimeFormatText (date) {if (date = null) {return null;} long diff = new Date (). getTime ()-date. getTime (); long r = 0; if (diff> year) {r = (diff/year); return r + "years ago" ;}if (diff> month) {r = (diff/month); return r + "Months Ago";} if (diff> day) {r = (diff/day ); return r + "Days Ago";} if (diff> hour) {r = (diff/hour); return r + "Hours Ago";} if (diff> minute) {r = (diff/minute); return r + "Minutes Ago";} return "just ";}

Method 5:

Use js plug-in: (original timeago. js)
