combine date and time into a single datetime [duplicate]

Question

I have a date and time control, which I would like to concatenate

var startDate = jQuery('#startDatepicker').find("input").val();
var startTime = jQuery('#startTimepicker').find("input").val(); 

I have another var field which has data as below:

var targetTime = new Date().setMinutes(-5).valueOf(); 

startDatepicker has the value as : 02/06/2017

startTimepicker, currentTime has the value as : 05:17 am

targetTime has the value as: 1486374940591

I want to concatenate startdate and starttime in the format of targetTime. How to concatenate the start date and start time? Thanks

Answer 1

This do what you need

var date = new Date(startDate + ' ' + startTime); 

jQuery('#startDatepicker, #startTimepicker').on('input', function() {
  var startDate = jQuery('#startDatepicker').val();
  var startTime = jQuery('#startTimepicker').val();
  var date = new Date(startDate + ' ' + startTime);
  console.log(date)
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Date
<input id="startDatepicker">Time
<input id="startTimepicker">

Pass your date and time to this function. It will return the Date object. Use getTime() on that to get the desired result. Codepen example.

function getAsDate(day, time)
{
 var hours = Number(time.match(/^(\d+)/)[1]);
 var minutes = Number(time.match(/:(\d+)/)[1]);
 var AMPM = time.match(/\s(.*)$/)[1];
 if(AMPM == "pm" && hours<12) hours = hours+12;
 if(AMPM == "am" && hours==12) hours = hours-12;
 var sHours = hours.toString();
 var sMinutes = minutes.toString();
 if(hours<10) sHours = "0" + sHours;
 if(minutes<10) sMinutes = "0" + sMinutes;
 time = sHours + ":" + sMinutes + ":00";
 var d = new Date(day);
 var n = d.toISOString().substring(0,10);
 var newDate = new Date(n+"T"+time);
 return newDate;
}
