Otherwise, the DOMRect object at index must be returned." Perhaps it should also define if it is zero or one based? (e.g. item(0) returns the first element if the list is non empty). 109040 1 dschulze 2014-07-17 07:49:15 +0000 I made DOMRectList an ArrayClass. Need to check with heycam if it is still required to explicitly specify if it is zero-based index 109062 2 a.cavalcanti 2014-07-17 17:44:46 +0000 Dirk If you are talking about a javascript Array class (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array), it is explicitly defined as "JavaScript arrays are zero-indexed". 109095 3 dschulze 2014-07-18 20:00:55 +0000 (In reply to Adenilson Cavalcanti from comment #2) > Dirk > > If you are talking about a javascript Array class > (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/ > Global_Objects/Array), it is explicitly defined as "JavaScript arrays are > zero-indexed".
