    The bug tracker is only for bugs in Prototype, not problems on your part due to wrong usage or missing understanding.

    Please use the mailing list http://groups.google.com/group/Prototypejs/ for your requests.

    Your issue was already discussed in https://prototype.lighthouseapp.com/projects/8886/tickets/666-make-.... Not bubbling blur/focus events is browser-default behaviour and thus your script does not work, as Event.on relies on event bubbling.

    • Assigned user set to “GitHub Robot”
    • Tag set to feature request

    Consider it a feature request as other projects like jQuery and FuseJS support it. (even prototype-ujs attempts to).
    Prototype's event delegation code, similar to MooTools, is merely a thin layer of sugar for the delegation pattern. It does not address any of the cross-browser issues.

    Anyway, there already is a ticket for this open (I linked to it in my previous comment), so this one should be marked as a duplicate.

    Well this one is more relevant as it points to current API requesting specific enhanced functionality.

    The other is a request to add support for cross-browser focusin/focusout.

    Also it is apparently evil (check out its ticket number, #666),
    That ticket is about 2 minutes away from crab walking down the stairs and spitting up pea soup :0
