agjCalendar is an agjjQuery.org plugin.

Examples

// The most basic agjCalendar integration
$('#text-input').agjCalendar();

// An alternative way of doing the same thing
$.agjCalendar({
  dateSelector: '#text-input'
});

// A more complex agjCalendar integration
$.agjCalendar({
  dateFormat:          'M j, Y',
  calendarCount:       3,
  inputType:           'text',
  dateSelector:        '#start-date',
  expanderSelector:    '#start-date-icon',
  minimumDate:         '2023-01-01',
  maximumDate:         '2023-12-31',
  defaultDate:         '2023-07-09',
  defaultEndDate:      '2023-07-10',
  allowRange:          true,
  minimumRange:        1,
  maximumRange:        7,
  defaultRange:        2,
  endDateSelector:     '#end-date',
  endExpanderSelector: '#end-date-icon'
});

There are other examples included in the GitHub repository and on agjCalendar.agjjQuery.org.

Options

When intializing an agjCalendar integration you can set its configuration options by passing a JSON object of values.

// A basic agjCalendar integration that will render a calendar that uses Monday to start the week
$.agjCalendar({
  dateSelector:      '#text-input',
  startWeekOnMonday: true
});

// Alternatively you can use the $.fn.agjCalendar() function for the same result
$('#text-input').agjCalendar({
  startWeekOnMonday: true
});

Date Format Options

The plugin uses common date formating for the dateFormat, dateFormatDate, dateFormatDateTooltip, dateFormatDayInput, dateFormatDayOfWeekTooltip, dateFormatMonthDropdown, dateFormatMonthInput and dateFormatMonthLabel options. You can choose any combination of the below characters to format dates for users. The characters are based on PHP’s DateTime::format function which is in turn based on C Standard Library’s strftime function.

Warning: This plugin does not support timezones, all dates and times are treated timezone agnostically

character description example(s)
Day --- ---
d Day of the month, 2 digits with leading zeros 01
D A textual representation of a day, three letters Sun
j Day of the month without leading zeros 1
l (lowercase ‘L’) A full textual representation of the day of the week Sunday
N ISO 8601 numeric representation of the day of the week 1 (for Monday) through 7 (for Sunday)
S English ordinal suffix for the day of the month, 2 characters st, nd, rd or th

Javascript Functions

The majority of the functionality for the agjCalendar plugin is self-contained but there are some functions that are added to extend jQuery that can be accessed by any of your Javascript code. We use the dollar sign alias ($) instead of the jQuery global for documentation but either can be referenced.

$.agjCalendar([options])

var integration = $.agjCalendar({
  dateSelector: '#text-input'
});
if (integration !== -1) {
  alert('The integration was a success!');
} else {
  alert('The integration failed; check your Javascript console for details.');
}

The $.agjCalendar() function accepts an options JSON object of values to initialize a new agjCalendar integration. Returns true if the integration was successful or false if it was not.

$.fn.agjCalendar([options] [, callback])

var integration;
$('#text-input').agjCalendar({
  dateFormat: 'Y-m-d'
}, function(returnValue) {
  integration = returnValue;
});
if (integration !== -1) {
  alert('The integration was a success!');
} else {
  alert('The integration failed; check your Javascript console for details.');
}

The $.fn.agjCalendar() function works similar to the $.agjCalendar() function but does not require the dateSelector option as you would be selecting the element and calling this function directly off of it. Returns the element to allow for chaining. This function also has an optional callback parameter that will be executed on completion of the integration attempt and will pass the integration attempt outcome into the callback’s first and only parameter.

$.agjCalendar.addRegexTextPattern(regexTextPattern)

$.agjCalendar.addRegexTextPattern('\u3040-\u30FF');

The $.agjCalendar.addRegexTextPattern() function will add a regular expression pattern to the plugin’s text checks. This function should be used if custom unicode characters are being used in custom translations. Our online documentation has more details on the translations page.

$.agjCalendar.dateToString(date, dateFormat[, translations])

var formattedDate = $.agjCalendar.dateToString(new Date(), 'j F Y');

The $.agjCalendar.dateToString() function will accept a date & date format and return a formatted string. It also accepts an optional translations parameters which is an object of translations (including day and month names) which will be used in the string, if no translations are passed the included English translations will be used. Read more about date format options and custom translations.

$.agjCalendar.deactivate()

$.agjCalendar.deactivate();

The $.agjCalendar.deactivate() function will deactivate any active date pickers.

$.agjCalendar.disable(position)

var integration = $.agjCalendar({
  dateSelector: '#text-input'
});
if (integration !== -1) {
  $.agjCalendar.disable(integration);
}

The $.agjCalendar.disable() function will disable an agjCalendar integration after it has been initialized.

$.agjCalendar.disableEmojiSupport()

$.agjCalendar.disableEmojiSupport();

The $.agjCalendar.disableEmojiSupport() function will disable emoji support for custom translations.

Warning: Emoji support will have issues with older versions of Microsoft Internet Explorer specifically 6, 7, 8, 9, 10 and 11 as they don’t support ECMAScript 2018. To support older browsers we recommend using $.agjCalendar.addRegexTextPattern() and passing each emoji character you want to use.

$.agjCalendar.enableEmojiSupport()

$.agjCalendar.enableEmojiSupport();

The $.agjCalendar.enableEmojiSupport() function will enable emoji support for custom translations.

Warning: Emoji support will have issues with older versions of Microsoft Internet Explorer specifically 6, 7, 8, 9, 10 and 11 as they don’t support ECMAScript 2018. To support older browsers we recommend using $.agjCalendar.addRegexTextPattern() and passing each emoji character you want to use.

$.agjCalendar.getIncludedTranslations(language)

var dateInFrench = $.agjCalendar.dateToString(
  new Date(),
  'j F Y',
  $.agjCalendar.getIncludedTranslations('fr')
);

The $.agjCalendar.getIncludedTranslations() function will return an object of translations for one of the plugin’s included translations.

$.agjCalendar.isActive()

if ($.agjCalendar.isActive()) {
  alert('There is a date picker currently active!');
} else {
  alert('There are no date pickers currently active.');
}

The $.agjCalendar.isActive() function will determine whether or not any date pickers are active. Returns true if a date picker is active or false if none are.

$.agjCalendar.stringToDate(string, dateFormat[, translations])

var extractedDate = $.agjCalendar.stringToDate('1 January 2000', 'j F Y');
if (extractedDate !== -1) {
  alert('Date successfully extracted: ' + extractedDate);
} else {
  alert('The date extraction failed.');
}

The $.agjCalendar.stringToDate() function will accept a string & date format and return a date object. It also accepts an optional translations parameters which is an object of translations (including day and month names) which will be used in parsing the string, if no translations are passed the included English translations will be used. Read more about date format options and custom translations.

Usage/Installation

You will need an HTML reference to jQuery in order for the plugin to function.

<!-- Reference to the agjCalendar CSS stylesheet -->
<style type="text/css">@import 'jquery.agjCalendar.min.css';</style>

Backwards Compatibility

The plugin strives to keep backwards compatibiltiy with all past releases. New features should be off by default with few exceptions. Changes to existing features should continue to support past options/values/configurations so older integrations of agjCalendar will continue to function without any need for change if their core plugin is updated.

List of Backward Compatibility Changes

version deprecated feature backwards support
v1.0.0 $.ctcCalendar() function The plugin was renamed from ctcCalendar to agjCalendar

The $.ctcCalendar() function is now an alias of $.agjCalendar()
v1.0.0 autoSetEndDate options true and false autoSetEndDate deprecated boolean values in favour of four possible strings ('always', 'never', 'blanks' and 'dates')

true is now an alias of 'always' and false is now an alias of 'never' for the autoSetEndDate option
v1.2.0 dayNameFormat option 'medium' dayNameFormat deprecated 'medium' in favour of 'abbreviated'

'medium' is now an alias of 'abbreviated' for the dayNameFormat option
v1.2.0 dateFormat options 1, 2, 3, 4 and 5 dateFormat was refactored to allow for custom formats

1 is now an alias of 'm/d/Y', 2 is now an alias of 'M j, Y', 3 is now an alias of 'd/m/Y', 4 is now an alias of 'Y-m-d' and 5 is now an alias of 'j F Y' for the dateFormat and dateFormatDateTooltip options
v1.2.0 $.agjCalendar returns -1 instead of false on failure Successful integrations function in the same manner but failures will now return -1 instead of false
v1.2.0 The z-index CSS values of the calendar and modal background elements now change dynamically based upon the integration elements when calendarDisplay is set to 'inline' Previously the z-index CSS value was always set to the maximum for the calendar element and maximum minus one for the modal background element when calendarDisplay was set to 'inline' which will still happen if the integration sets the forceMaxZIndex option to true (which is set to false by default)
v1.2.0 The autoBlur option will be automatically set to true when the calendarDisplay option is set to 'modal' or 'full' Previously all integrations of agjCalendar had the false behaviour which is still the case for integrations with the calendarDisplay set to 'inline' and can still happen if the autoBlur option is set to false

Older Versions of jQuery

The plugin is designed to work with the newest version of jQuery (3.7.1) but will also work with older versions of jQuery 3.x as well as jQuery 2.x (tested up to 2.2.4) and jQuery 1.x (tested up to 1.12.4). We recommend using the newest version of jQuery.

Unit Testing

The plugin uses jQuery’s QUnit framework for unit testing. All units tests are located in the qunit.js file. The unit tests can be run online in-browser at agjCalendar.agjjQuery.org/tests/index.html. We strive to cover all public facing functions and API’s to ensure all permutations of parameters, options, fail scenarios, success scenarios, etc. are covered. Many novel scenarios are included in the unit tests to achieve high code coverage.
