javascript - How to integrate datetimepicker with ASP.NET localisation -

i'm using trent richardson's datetimepicker extension jquery, obtained via nuget: http://trentrichardson.com/examples/timepicker/

trent's documentation says can create localised datetimepicker this:

$('#basic_example_4').timepicker(     $.timepicker.regional['es'] ); 

i'm attaching datetimepicker asp.net textbox setting cssclass property on textbox, , having javascript attach datetimepicker selecting on css class:

<script type="text/javascript">     $(document).ready(function () {         $('.calendarstartdatetime').datetimepicker({             dateformat: 'yy-mm-dd',             timeformat: 'hh:mm tt',             controltype: 'select',             oneline: true         });     }); </script> ... <asp:textbox id="startdatetime" runat="server" cssclass="calendarstartdatetime" meta:resourcekey="startdatetimeresource1"></asp:textbox> 

my asp.net page declaration sets culture="auto" , uiculture="auto" asp.net elements pick culture settings browser settings (and can use asp.net resources localise text).

i datetimepicker automatically apply localisation based on browser settings, consistently how server-side components being localised. how achieve this? need insert asp.net tag javascript, like:

<script type="text/javascript">         $(document).ready(function () {         $('.calendarstartdatetime').datetimepicker({             $.timepicker.regional[<% magic happens here %>],             controltype: 'select',             oneline: true         });     }); </script> 

or should browser culture detected in pure javascript?

edit: based on @smirnov's answer, final code timepicker was:

<script type="text/javascript">     $(document).ready(function () {         $('.calendarstartdatetime').datetimepicker(             $.extend(                 {},                 $.datepicker.regional['<%= system.globalization.cultureinfo.currentculture.twoletterisolanguagename %>'],                 $.timepicker.regional['<%= system.globalization.cultureinfo.currentculture.twoletterisolanguagename %>'],                 {                     dateformat: 'yy-mm-dd',                     timeformat: '<%= system.globalization.cultureinfo.currentculture.datetimeformat.shorttimepattern %>',                     controltype: 'select',                     oneline: true                 }             )         )     }); </script> 

this code correctly merges regionalisation settings jquery's built-in datepicker, trent richardson's timepicker properties, , custom settings.

use cultureinfo.currentculture.twoletterisolanguagename

as timepicker seems use country code value regional, try

... $.timepicker.regional['<%=system.globalization.cultureinfo.currentculture.twoletterisolanguagename%>'], ...
