jQuery UI Datepicker onChangeMonthYear Option

Last Updated : 19 Mar, 2021

jQuery UI consists of GUI widgets, visual effects, and themes implemented using jQuery, CSS, and HTML. jQuery UI is great for building UI interfaces for the webpages. The jQuery UI Datepicker onChangeMonthYear option is called when the datepicker moves to a new month or year. The onChangeMonthYear option holds a function that receives the selected year, month (1-12), and the datepicker instance as parameters.

Syntax:

onChangeMonthYear: Function( Integer year, 
    Integer month, Object inst )  {  }
