Comment #6 on issue 2218 by math...@qiwi.be: HTML extensions to String.prototype must throw an error if the `this` object is not coercible (i.e. `null` or `undefined`)
http://code.google.com/p/v8/issues/detail?id=2218
Correction: Safari/JavaScriptCore do perform the CheckObjectCoercible step correctly. The bug I linked to was an old one that has been resolved for a while now.
Only Chrome/V8 and IE/Chakra do not perform the step. -- v8-dev mailing list v8-dev@googlegroups.com http://groups.google.com/group/v8-dev
