If in a page there is a event (like onclick) and it ends with a "return false;", if the event is triggered with .click() it still propagates and does the default behavior instead of being canceled.

Its not even the same behavior as clicking the button with the mouse.

I see that the result of those events is being stored in event.result ... so here is my tentative fix:

jQuery.Event.prototype.effectiveResult = function() {

return this.result !== undefined ? !this.result : false;

}

jQuery.Event.prototype.isDefaultPrevented = jQuery.Event.prototype.effectiveResult;

jQuery.Event.prototype.isPropagationStopped = jQuery.Event.prototype.effectiveResult;

jQuery.Event.prototype.isImmediatePropagationStopped = jQuery.Event.prototype.effectiveResult;
