The problem with this, and where I see ASPX's advantage, is that you can build the "on form submit" so it's tied to ONE instance of the button. In your example, this would apply to ALL instances.
However, again, this is certainly doable in CF. If ASPX uses a second file <filename>.aspx.cs to contain such code, you could easily make button.cfm check for the existence of such a file and then include it so it could call custom event handlers for your specific button. ======================================================================== === Raymond Camden, ColdFusion Jedi Master for Mindseye, Inc (www.mindseye.com) Member of Team Macromedia (http://www.macromedia.com/go/teammacromedia) Email : [EMAIL PROTECTED] Blog : www.camdenfamily.com/morpheus/blog Yahoo IM : morpheus "My ally is the Force, and a powerful ally it is." - Yoda > -----Original Message----- > From: jon hall [mailto:[EMAIL PROTECTED] > Sent: Thursday, July 17, 2003 12:51 PM > To: CF-Talk > Subject: Re: MSDN on CF -> ASP.net > > > See Raymond's response :) > > <cfif isDefined("caller.form")> > //hmmm spotted problem...should name defaults differently > <cfif attributes.value NEQ value> <--- onChange > <cfset value = "Form submit successful and you > changed the default!"> > <cfelse> > <cfset value="Form submit successful!"> > </cfif> > </cfif> > > Could probably go really far and define onChange, onSubmit, > etc. methods for each input.
