locale attribute

A two-letter ISO 639-1 language code can be provided as shorthand for several of the options listed above. Currently supported languages: en, fr, ja, fi, es, hu, sv, nl, ru and no. If the locale attribute is used it overrides dayLabels, monthLabels, dateFormat, todayBtnTxt, firstDayOfWeek and sunHighlight properties from the options.

selDate attribute

Provide the initially chosen date that will display both in the text input field and provide the default for the popped-up selector. Must be in the same format as the dateFormat option is.

defaultMonth attribute

If selDate is not specified, when the datepicker is opened, it will ordinarily default to selecting the current date. If you would prefer a different year and month to be the default for a freshly chosen date picking operation, specify a [defaultMonth] attribute.

Value of the [defaultMonth] attribute is a string which contain year number and month number separated by delimiter. The delimiter can be any special character. For example the value of the [defaultMonth] attribute can be: 2016.08, 08-2016, 08/2016.

  • event.epoc: Epoc time stamp number: 1479765600

}
