How to validate a date in a validation script

[Former Community Member]

I have a date field for which I have set a validation pattern using its Object palette i.e. Object > Value tab > Validation Pattern > Validation tab. The validation pattern I have there is simply 'date{YYYY-MMM-DD}' with an error message set in the Validation Pattern Message box.

How do I perform this same validation using a javascript in the Validation event?

I'd like to use a script instead so that I can better control when this validation will be performed.

Thanks!!

Marc:

If your field has a display picture clause, then you can detect if it formatted correctly by looking at field.formattedValue

Specifically, if the value cannot be formatted, the formattedValue will be the same as the rawValue (unformatted).

So a validation script that specifies:

this.formattedValue !== this.rawValue;

should detect invalid dates.

good luck
