That is how far you review all your actions, is it not? “Might have been caused”… document.write() has never been suitable for debugging from the *console*, because document.write() after the document has been loaded overwrites it in memory/viewport in an unsafe fashion (there should be document.open() before and document.close() afterwards); hence window.alert() and console.log(…). > It worked when I inserted the script into a web page. > Here's the last version: > […] If only it were not your usual unreadable, undertested junk. That said, Object.get*Own*PropertyNames() and Array.prototype.forEach() have been introduced with ECMAScript Edition 5 at the earliest (some implementations probably had it before it was in the Specification), and does not suffice for enumerating the properties of objects. -- PointedEars FAQ: <http://PointedEars.de/faq> | SVN: <http://PointedEars.de/wsvn/> Twitter: @PointedEars2 | ES Matrix: <http://PointedEars.de/es-matrix> Please do not cc me. / Bitte keine Kopien per E-Mail.
