Error checking on Null return data

[tmf]

I have an application where you query data against a date range. You fill in the requested date ranges and submit, and the return data displays the actual date ranges for the data returned.

Something like:
Requested Date Range: 2003-12-20 to 2003-12-29
Actual Date Range: 2003-12-20 to 2003-12-22

I need to present the user with a statement if there is no return data for the dates requested. In other words the actual date values are null.

Requested Date Range: 2003-12-20 to 2003-12-29
Actual Date Range: to

I am a javascript beginner so please keep that in mind.

Thank you very much for your thoughts.

What are the varibles that check the data ranges

Jammer,

The variables are as follows:

fromDate
toDate

HTH.

Tim,

You haven't given me much to go on, but would something like this do the trick:

	function checkDates()
	{
		if ((fromDate == '' || typeof(fromDate) == 'undefined') && (toDate == '' || typeof(toDate) == 'undefined'))
			alert('There was no data returned!');
		else
			alert('Here\'s your data:...');
	}
