http://issues.apache.org/bugzilla/show_bug.cgi?id=37134 ------- Additional Comments From [EMAIL PROTECTED] 2005-10-18 07:32 ------- Yes, Prototype is evil. Not only does it add a property to Object, it also adds properties to other fundamental JavaScript types, such as Array. This is very antisocial behaviour for a toolkit, and pretty much hoses any usage of the 'for ... in ...' construct in existing JavaScript code, unless that code was very carefully written to work around exactly that behaviour. Another big issue with Prototype is that it is not namespaced. All of its classes are defined directly within the global JavaScript namespace, and it defines some classes with names that are quite likely to exist in application code (e.g. Form, Field). This has the potential for creating serious havoc, especially in portal / portlet environments. Of course, one of the big issues with the Commons Validator JavaScript code is that it too is not namespaced. ;-( That's something that needs fixing. It's not that hard to fix, but the changes would introduce new rules for people writing custom validators. It's most definitely do-able, though, and needs to be done. Prototype's increasing popularity, ironically, makes it decreasingly likely that the serious deficiencies will be rectified, since that would mean breaking lots of existing code. So I guess for Commons Validator, at least, we'll need to code around those deficiencies. That too can be done - it's just a pain in the butt, adds more code, and shouldn't be necessary. Personally, I'm going to focus my client-side efforts on Dojo[1], a properly written toolkit that doesn't have these kinds of problems, and I wish the folks who want to use Prototype, and its derivatives, the best of luck. :-) [1] http://dojotoolkit.org/ -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
