A more consistent approach would be using the return value instead of a new
parameter:

  if (listener(ev) === false)
    ev.preventDefault();

That's essentially what you get with onclick and such.

[Thomas Greiner, 2014/08/19 09:32:34]

Done.

[Wladimir Palant, 2014/08/18 12:31:19]

This should assign !preventDefault - see onclick="return false;" (return true
would allow the default handling to execute).

[Thomas Greiner, 2014/08/19 09:32:34]

Done.
