[Javascript] required entry field

According to MS, it does not cancel.

What do you mean by unpleasantry though? I would naturally think this
is how it would work since onBlur means it actually had a blur event
occur.  So to cancel something that already happened would be pointless.

Now if there was an onbeforeblur (which there isn't), maybe it'd be
possible.
