The delete operator usage is supported in both Firefox 2+ and Internet Explorer 8. 80858 1 beidson 2008-05-18 14:30:42 -0700 In hitting up the spec to see if it mentions the delete storage.property; syntax as an alias for removeItem(property), I see that the specific mentioning of enumeration and property matching in general has been stricken. I wonder when this happened? 80859 2 beidson 2008-05-18 14:40:34 -0700 If we decide to fix this, there's no reason it will be SessionStorage-only - it will be all Storage interfaces 80861 3 beidson 2008-05-18 15:20:57 -0700 I did a little exploring into some recent revisions of the spec and tracked down why the enumeration stuff was removed. I've emailed WHATWG about that omission and also to raise the point about the delete syntax - http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2008-May/014848.html In the meantime, I can't see the harm in supporting this... 80863 4 beidson 2008-05-18 15:36:16 -0700 Hixie confirmed on IRC that the [XXX] placeholder in the storage interface is meant to imply delete support on removeItem(). I'm adding this now while I have a few free cycles 80868 5 beidson 2008-05-18 16:52:45 -0700 Landed r33565
