Get the selected Date and Time on KendoDateTimepicker

Question

I am using a kendo DateTimepicker. I have a startdate and end date. when i select a start date i want the end date to be generated 30min more than the start date. For example if the selected start date is 5/11/2016 2.30PM i want the end date to be 5/11/2016 3.00PM.. Can anyone help me with this.

Thanks

kendo Code:

 <tr>
    <td>
        <div>
          <label for="start_date" >Start Date</label>
        </div>
          <div data-container-for="data.start_date" onchange="startDate()">
         <input data-role="datepicker" data-bind="value: data.start_date" id="startDate"/>
         <input data-role="timepicker" data-bind="value: data.start_date" id="startTime"/>
       </div>
   </td>
       <td>
           <div>
              <label for="end_date">End Date</label>
           </div>
              <div data-container-for="data.end_date">
               <input data-role="datepicker" data-bind="value: data.end_date" id="endDate" />
               <input data-role="timepicker" data-bind="value: data.end_date" id="endTime"/>
             </div>
       </td>
</tr>


Function:

  function startDate() {
                var startDate = kendo.toString($("#startDate").data("kendoDatePicker").value(), 'MM/dd/yyyy');
                var startTime = kendo.toString($("#startTime").data("kendoTimePicker").value(), 'hh:mm tt')
                var endtDate = kendo.toString($("#endDate").data("kendoDatePicker").value(), 'MM/dd/yyyy');
                var endTime = kendo.toString($("#endTime").data("kendoTimePicker").value(), 'hh:mm tt')
                var StartDate = new Date($("#startDate").val());
                var futureDateTime = new Date(StartDate.setMinutes(StartDate.getMinutes() + 30));
                var End = $("#endDate").data("kendoDatePicker").value(futureDateTime);
                var EndTime = $("#endTime").data("kendoTimePicker").value(futureDateTime);

    }

Where are you creating your datepicker? $("#start") is just a label so doing $("#start").data("kendoDatePicker") is probably null or undefined — KSib, May 11 '16 at 21:56
Sorry i added the $("start") to the datepicker but still not working — Nethra, May 11 '16 at 22:01
Can you post the code in your actual aspx/ascx/cshtml? This seems like a dump after the page has rendered already. Something like shown here would be great http://demos.telerik.com/kendo-ui/datepicker/index — KSib, May 11 '16 at 22:05
here is he Updated code i am getting the selected start date value to Datepicker varaible but how will we assign this to the end date — Nethra, May 11 '16 at 22:08

Please try with the below code snippet. On click on button you get separate date and time of both datetime pickers.

<div>
    <input id="startDate" />
    <input id="endDate" />
    <button onclick="GetDateAndTime();">Get date an time separatly</button>
    <script>
        function GetDateAndTime() {
            var startDate = kendo.toString($("#startDate").data("kendoDateTimePicker").value(), 'MM/dd/yyyy');
            var startTime = kendo.toString($("#startDate").data("kendoDateTimePicker").value(), 'hh:mm tt')
            var endtDate = kendo.toString($("#endDate").data("kendoDateTimePicker").value(), 'MM/dd/yyyy');
            var endTime = kendo.toString($("#endDate").data("kendoDateTimePicker").value(), 'hh:mm tt')
            alert(startDate);
            alert(startTime);
            alert(endtDate);
            alert(endTime);
        }
        $(document).ready(function () {
            var tempDate = new Date();
            $("#startDate").kendoDateTimePicker({
                value: tempDate,
                change: onchange
            });
            $("#endDate").kendoDateTimePicker({
                value: tempDate,
            });
            $("#startDate").data("kendoDateTimePicker").trigger("change");
            function onchange() {
                var startDate = new Date($("#startDate").val());
                var newDateTime = new Date(startDate.setMinutes(startDate.getMinutes() + 30));
                $("#endDate").data("kendoDateTimePicker").value(newDateTime);
            }
        });
    </script>
</div>

Let me know if any concern.

Thanks it worked ...initailly when start time is 12.00am the end time is 12.30 am but when i change time to 1.00am time is not changing to 1.30am in my case with my snippet and your function — Nethra, May 12 '16 at 16:20
Could you please provide fiddle for same? So I can reproduce your issue. — Jayesh Goyani, May 12 '16 at 16:26
I added the image and updated the function can you check it unable to make fiddle as it using data — Nethra, May 12 '16 at 17:01
Jayesh, I would prefer if you are going to copy and paste my code you should either say you did so or simply modify my code to fit the requirements. It's not a good look to do what you're doing. I believe this is the second time I've seen you do this. — KSib, May 16 '16 at 17:09

Can you help me in retrieving Date and Time separately if possible. The date is being added but not the time. — Nethra, May 11 '16 at 23:24
' function startChange() { var currentDate = new Date(); var Start = $("#start").data("kendoDatePicker").value(); var StartTime = $("#starttime").data("kendoTimePicker").value(); var futureDateTime = new Date(Start.setMinutes(Start.getMinutes() + 30)); var End = $("#end").data("kendoDatePicker").value(futureDateTime); var EndTime = $("#endtime").data("kendoTimePicker").value(futureDateTime); }' — Nethra, May 11 '16 at 23:26
