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.

From the update area within the bootstrap datepicker, it seems very clear that the options specify updating values. bootstrap-datepicker.readthedocs.io/en/latest/… – Stain

I saw that already, it changes values but not options – Gonagle

Try the format option. bootstrap-datepicker.readthedocs.io/en/latest/… – Stain

looks great but I would like to update options at once, there is also some other properties that need to be updated like viewMode and language – Gonagle

Language is one of the properties and I believe format as well. – Stain

how can I change the viewMode? – Gonagle

I am having a hard time trying to find how to change a simple option LOL – Gonagle

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);
});

I was about to change to datepicker "v4" but it does not seem to be an official site, I do not know if you have observed that there is a lot of bootstrap "datepickers" and "datetimepickers" sites that got the people confused and do not know which one to use, I only use bootstraps built-int. I appreciate your answer and will use that, Regards. – Gonagle

Unfortunately bootstrap itself does not include a datepicker, but there are a lot of independent datepickers with bootstrap theme. In my opinion, the best one is bootstrap-datetimepicker by eonasdan. It uses momentjs, it has a rich API and it's well documented. – Vocable

You can find all about new version (Bootstrap 3 Datepicker v4 Docs) at https://eonasdan.github.io/bootstrap-datetimepicker/.

let new_options = {
    icons: {
        time: "fa fa-clock-o",
        date: "fa fa-calendar",
        up: "fa fa-chevron-up",
        down: "fa fa-chevron-down",
        previous: 'fa fa-chevron-left',
        next: 'fa fa-chevron-right',
        today: 'fa fa-screenshot',
        clear: 'fa fa-trash',
        close: 'fa fa-remove'
    },
    format: 'DD/MM/YYYY',
    date: new Date()
}

if(condition1){
        new_options.daysOfWeekDisabled = [0,2,3,4,5,6];
        new_options.viewMode = 'years';
        new_options.format = 'MM/YYYY';
    }else(condition2){
        new_options.viewMode = 'years';
        new_options.format = 'YYYY';
    }
    // Destroy previous datepicker
    $('.datetimepicker').data("DateTimePicker").destroy();
    // Re-int with new options
    $('.datetimepicker').datetimepicker(new_options);

Sorry for my poor english please :)

Answer 3

Here I have a hacking solution that works for me to change the datepicker options dynamically after I initiate a bootstrap datepicker object.

var id = "MyDatepicker"
var beginDate = new Date();
var endDate =  new Date(2022, 11, 17, 3, 24, 0);

function myCallBack(date) {
    if ((beginDate <= date) && (date <= endDate)){
        return {classes: 'activeClass'};
    }
    return;
}

$('#' + id ).datepicker({
    startDate: new Date(),
    language: 'en'
});

$('#' + id ).datepicker('_process_options', {
    beforeShowDay: function(date) {
        return myCallBack(date);
    }
}).datepicker('update','')

In this case. I apply a class to a range of dates on the datepicker.

I use the "non public" datepicker method '_process_options' to change intern datepicker methods.

With this method I can change all the options of the datepicker instance because the '_process_options' has no method validator.

Also I use the method 'update' bacause the dobbleclick bug: bootstrap datepicker, beforeShowDay works after second click
