Good day. Facebook has a nice feature. It allows you to track the time of the store relative to the time of the user. And accordingly write "Open now" or "open on Monday at 8-00."

How to implement this? Is there something similar?

Facebook example

  • And what did you fail? And give an example here, the link is not clear (without authorization is not visible). - user207618
  • Corrected the link. Under the "Call" button there is the text "Event Organizer in Minsk" Open Now - Pavel Zhukovsky
  • one
    And what's your problem? Calculate the difference of the belts, find out the user's time (the Date object to help) and put an inscription on the results. - user207618

I came up with such a solution. Days and time (hours and minutes) stored in json.

 var utc_vendor = '+3'; var utc_user = '-1'; wt = { "days": { "2": {"1":"1","2":"2","4":"4","6":"6"}, "3": {"1":"1","3":"3","7":"7"} }, "time_from_h": { "2": {"1":"8","2":"9","4":"8","6":"10"}, "3": {"1":"8","3":"9","7":"8"} }, "time_from_m": { "2": {"1":"00","2":"05","4":"30","6":"50"}, "3": {"1":"10","3":"00","7":"10"} }, "time_to_h": { "2": {"1":"21","2":"20","4":"22","6":"18"}, "3": {"1":"19","3":"17","7":"19"} }, "time_to_m": { "2": {"1":"30","2":"40","4":"40","6":"52"}, "3": {"1":"59","3":"10","7":"40"} } }; var d = new Date(); var hours = d.getHours(); var minutes = d.getMinutes(); var w_day = [7, 1, 2, 3, 4, 5, 6][new Date(d).getDay()]; var wd_name = {"7": "воскресение", "1": "понедельник", "2": "вторник", "3": "среду", "4": "четверг", "5": "пятницу", "6": "субботу"}; function get_vendor_time_status(id) { var hv = 0; if(wt.days[id]) { if(wt.days[id][w_day] && ((wt.time_from_h[id][w_day] < hours && hours < wt.time_to_h[id][w_day]) || ((wt.time_from_h[id][w_day] == hours && wt.time_from_m[id][w_day] <= minutes) || (hours == wt.time_to_h[id][w_day] && minutes <= wt.time_to_m[id][w_day])))) { alert('Сейчас работает'); } else { if(w_day == 7) w_nd = 1; else w_nd = w_day + 1; for(i = 1; i < 8; i++) { if (wt.days[id][w_nd]) { if(w_nd == 2) { alert( 'Откроется во ' + wd_name[w_nd] + ' в ' + wt.time_from_h[id][w_nd] + ':' + wt.time_from_m[id][w_nd] + '.' ); } else { alert( 'Откроется в ' + wd_name[w_nd] + ' в ' + wt.time_from_h[id][w_nd] + ':' + wt.time_from_m[id][w_nd] + '.' ); } break; } if(w_nd == 7) w_nd = 1; else w_nd = w_nd + 1; } } } } get_vendor_time_status(2);

  1. Is it possible to optimize the code?
  2. Now the situation is when all data is displayed in the same time zone. I know the time zone of the seller. It is in it that he indicates the time of work. Is it possible to somehow adjust the time depending on the time zone of the seller and the time zone of the user?
