Sunday Validation

[rosepremo]

I have 2 date/time fields in a timesheet form.  Currently, users can pick any date they want in the first, and the second populates with a date 6 days later.  I'm not sure how to validate that the day they pick is a Sunday.  Is that possible with scripting??

Thanks in advance,

Rose.

Not without scripting .....you can turn the date chosen into a javascript date object and then there is a js function that will return you the day of the week for that particular date.

The attached validates the first date entered is a Sunday and calculates the second date as 6 days from the first date.

// form1.page1.date1::exit - (FormCalc, client)

// Get the number of days since epoch (Jan 1, 1900).

var dateNum = Date2Num($.formattedValue,"MM/DD/YYYY")

// Convert the number of days to the full weekday name.

dayOfWeek.rawValue = Num2Date(dateNum,"EEEE")

// Calculate 6 days from the chosen date by adding 6 to the number of days since the epoch.

date2.rawValue = Num2Date(dateNum+6,"MM/DD/YYYY")

if (dayOfWeek.rawValue ne "Sunday") then

          xfa.host.messageBox("Date1 must be a Sunday.");

endif
