Update bootstrap 3 datepicker options dynamically?

Question

This datepicker it is already created with other default options, but I need to update it with the following new options and it does not seem to work:

// new options
var new_options = {
    format: 'dd/mm/yyyy',
    autoclose: true,
    language: 'es'
}

// update values
$("#fecha_periodo").datepicker("update", new_options );

I would also like to update other options like daysOfWeekDisabled, viewMode and so on.

Answer 1

Unfortunately, there is no API to change options dinamically, all availables methods are listed here (you can use setDaysOfWeekDisabled to set dinamically days of week disabled).

You can use destroy method to destroy datepicker instance and build it again with the new options.

Here a live example:

$('#datepicker').datepicker();

$('#btnChange').click(function(){
  var new_options = {
    format: 'dd/mm/yyyy',
    autoclose: true,
    language: 'es'
  }
  // Save value
  var value = $('#datepicker').datepicker('getDates');
  // Destroy previous datepicker
  $('#datepicker').datepicker('destroy');
  // Re-int with new options
  $('#datepicker').datepicker(new_options);
  // Set previous value
  $('#datepicker').datepicker('setDates', value);
});
