select 1.4.6

Triggered when a date/time selection is made.

function( startDate, endDate, allDay, jsEvent, view )

startDate is a Date object indicating the beginning of the selection.

endDate is a Date object indicating the end of the selection. It follows the same rules as the Event Object for inclusivity/exclusivity: when allDay is true, endDate includes the last day.

allDay is a boolean indicating if entire days were selected (days in month view or the “all-day” slot in the agenda view) or time slots were selected.

jsEvent holds the primitive JavaScript event with information such as mouse coordinates. If select has been triggered via the select method, jsEvent will be undefined. (added in version 1.4.7)
