Adobe LiveCycle Date/Time Field Scripting Question

Question

I have a date/time field in Livecycle which the end user chooses a random date from.  I need to populate a date 180 days from this date for an eligible to date/time field.  I have tried various javascript and formcalc options with no success.

Answer 1

Try this site here for a reference: http://eslifeline.wordpress.com/2008/09/26/date-manipulation/
The following was the use case. A form has 2 TextFields Start_Date and End_date
User enters a certain date in the Start_Date text field for example 09/24/08 (MM/DD/YY)
The End_Date should add 90 days to the Start_date and populate the End_Date
The following script would do that
var current = Date2Num(Start_Date.rawValue, “MM/DD/YY”)
var future = current+90
var newDate = Num2Date(future,”MM/DD/YY”)
form1.#subform[0].End_Date.rawValue = newDate 
Validating End Date is later than Start Date
var diff = Date2Num(EndingDate.rawValue, “YYYY-MM-DD”) – Date2Num(StartingDate.rawValue, “YYYY-MM-DD”)
if (diff > 0) then
xfa.host.messageBox(“The End date is later than start date”)
else
xfa.host.messageBox(“PLEASE CHECK….The End date is before the start date”)
endif
