jQuery parser finds custom Array.prototype methods

[victor-homyakov]

jQuery parser in jQueryGeneric() has for ... in loop on array of event handlers. When oEvents is Array (at least in jQuery 1.6.4) and some custom methods are added to Array.prototype (e.g. shuffle etc.), they all are enumerated in this loop and added as handlers for this particular event:

                for ( j in oEvents ) {
                    var aNodes = [];
                    ...
                        aNodes.push( eventAttachedNode ); // aNodes.push("keydown");
                        ...
                        if ( typeof oEvents[j].origHandler != 'undefined' ) { // typeof oEvents.shuffle.origHandler === 'undefined'
                            func = oEvents[j].origHandler.toString();
                        }
                        else if ( typeof oEvents[j].handler != 'undefined' ) { // typeof oEvents.shuffle.handler === 'undefined'
                            func = oEvents[j].handler.toString();
                        }
                        else {
                            func = oEvents[j].toString(); // func = Array.prototype.shuffle.toString();
                        }
                        ...

If oEvents is Array in all jQuery versions then better will be usual for loop.
