Javascript Console - Prototype Inheritance Chain

[Bruce Rosenberg]

Hello,

I noticed when both logging Javascript variables to Chrome's console
and viewing Javascript variables in the script debugger, that Chrome
does not display inherited object properties from the prototype
inheritance chain; only those defined in the derived object. Is this
'as designed' behavior or a bug or is there some way to turn the
feature on? At the moment I'm having to fall back to Firefox/Firebug
to get the full picture of my running code. I'm using Chrome
8.0.552.210 beta.

Thanks.

Is what you're looking for the __proto__ property? Seems to be on most
objects, and looks like it shows stuff that's inherited. Try, for
instance, document.body.__proto__, or foo.__proto__, where foo is pretty
much any object.

No problem, glad I could help.

P.S.: Make sure you keep the list CC'd, so others can hear what you have
to say. ;-)
(Usually clicking "reply to all", or "reply to list" is enough, if your
mail client has them. Opera tends to put the list in the "To" field--don't
know if that's a bad thing or not, but I just copy it to the CC field
manually.)
