I think your problem is this: * eval( this.name + 'Data' ) // I assume this.name+'Data' turns into the ID of an input element that should contain some data.
If this.name is myObjectName then the above becomes: * eval( 'myObjectNameData' ) Which when eval'ed returns an anonymous string value or possibly nothing. I believe you want eval( $(this.name+'Data').value but that will throw an error if the object doesn't exist. You could throw a try/catch around it, but that means you will have to do error catching elsewhere. -Andrew Martinez -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jason Hummel Sent: Wednesday, May 24, 2006 2:50 PM To: [email protected] Subject: [Rails-spinoffs] newbie oo question Hey everyone, I'm trying to create an object that will have some properties predefined, but will allow me to pass in properties to override those standard props if needed. I'm trying something like: var myObject = Class.create(); myObject.prototype = { initialize: function(element, options) { this.element = $(element); this.name = this.element.id; this.options = Object.extend({ data: eval(this.name + 'Data') }, options || {}); }, What I want is the this.options.data property to default to a JSON object that has the convention of: id of element + 'Data', so if you have this object in your javascript you don't have to do anymore work. If you want to pass in a different object though you can do so like: new myObject('elementID',{data: myJSONObject}) It works great if no object is passed as an argument, but when I try to pass a data param through nothing happens. I don't even get an error. I can pass other things through like: new myObject('elementID',{foo: myJSONObject}) and I'll be able to alert out myObject.options.foo, it's only when I'm trying to override my default data property, I run into trouble.
