A quick way to do it (ugly admittedly) is to use the 'instanceof' or 'typeof' operator.
if ( obj[propertyName] instanceof Date ) You might need to cast into number or date before you check the instance of to see if it is valid. -----Original Message----- From: viraf_bankwalla [mailto:[EMAIL PROTECTED] Sent: Monday, April 04, 2005 10:06 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: AS - adding dynamic properties to an object Thanks - the example below would have worked if I had knowledge of the property name when I wrote the code. This is not the case (the property name is retrieved with a service request). The solution that I found was to use the associative array syntax - obj[propertyName] = yy; Now the next question is that how do I specify that "propertyName" is of a given type - say Date or Number.
