Hi Brady. Brady Eidson: > A little while ago, this change - > http://html5.org/tools/web-apps-tracker?from=1429&to=1430 - was meant to > "update the spec for consistency with WebIDL" > > In this change, the following passage was removed from the Storage > section: > > "In the ECMAScript DOM binding, enumerating a Storage object must > enumerate through the currently stored keys in the list the object is > associated with. (It must not enumerate the values or the actual members > of the interface). In the ECMAScript DOM binding, Storage objects must > support dereferencing such that getting a property that is not a member > of the object (i.e. is neither a member of the Storage interface nor of > Object) must invoke the getItem() method with the property's name as the > argument, and setting such a property must invoke the setItem() method > with the property's name as the first argument and the given value as the > second argument." > > Shorty thereafter, the declaration of the Storage interface was changed > to the following: > > interface Storage { > readonly attribute unsigned long length; > [IndexGetter] DOMString key(in unsigned long index); > [NameGetter] DOMString getItem(in DOMString key); > [NameSetter] void setItem(in DOMString key, in DOMString data); > [XXX] void removeItem(in DOMString key); > void clear(); > }; > > I assumed that the WebIDL descriptions of [IndexGetter], [NameGetter], > and [NameSetter] would keep the specified functionality in tact, but it > appears this is *not* the case. > Or by reading http://dev.w3.org/2006/webapi/Binding4DOM/ I can't find > where it is the case... > > Does someone know what is up with this? Yeah, Web IDL doesn?t currently have a way to make a property DontEnum, so the IDL there isn?t strictly equivalent to the prose that used to be there. > While I'm on the topic, I'm also curious about that [XXX] placeholder. > There's a bug in WebKit's bugzilla pointing out that the IE8 beta and > Firefox 2 both support `delete storage.keyName` syntax as an alias for > `storage.removeItem(keyName)` > I'm taking a guess here and assuming supporting the `delete` syntax is > the implied concept behind [XXX] Yes. > Not that this mailing list has direct impact on the WebIDL spec, but I > would suggest [NameDeleter] or [NameRemover] as a placeholder in the > HTML5 spec since it fits in with the NameGetter/Setter family of > operations quite nicely. They?re sensible names. I?ll append() that on my TODO list. Thanks, Cameron -- Cameron McCormack ? http://mcc.id.au/
