I have 2 calendars attached to the 2 input box. and I want to validate that first input box date should always come before the other text box. let say
so in any condition, this should qualify start_date<end_date.
Calendarprovides onClick event. Its handler gets object of selected date as a parameter. It can be used for validation:
calendar.attachEvent(“onClick”, function(date){
/your code here/
})
