Validating Date Parameter

Swathi1985

I have a report where in i allow the user to enter date in the format yyyy-MM-dd.
I want to validate the date and prevent user from entering the report if date is invalid (eg. 2010-26-43).
Can you please provide sample code on how to achieve this using script in BIRT?
Thanks in advance.

The link you provided talks about comparing two dates. What i want is how to validate if the date entered is
valid in the first place. You know what i am saying.
My Date format is yyyy-MM-dd.

I want to notify user if he enters some invalid date like say
2012-25-40

That is already a function of the parameter object.

If you have set the Data Type to Date or Date Time, only valid formats will validate.

This required no additional validation processing.

In the attached design, type "kjt56" in the parameter field, and see the failure.

If you need to validate a date outside of the parameter object:

var timestamp=Date.parse(params["dateValidation"].value);
isNaN(timestamp);

Please try to enter the date as 2012-19-56 in the report you have attached.
Though it is invalid, it ll be displayed as Aug 25, 2013 in the report.
I was expecting it to error out actually but that's not happening.

Swathi, I entered the string you suggested and for me, it failed validation just as it should.

What version of BIRT, and what IDE?
