observe_field does not use :on option

Reported by grosem | September 22nd, 2008 @ 11:25 AM | in 2.x

According to the documentation it is possible to specify a :on option like focus or blur. But no matter what you use, it uses only the onchange behaviour. This seems to be an old bug as there are many forum entries about this topic.

    This isn't a rails bug, really. The ability for prototype's Form.Element.EventObserver to observe specific events was actually removed over 2 and a half years ago, in this commit. Hard to tell whether this was intentional.

    Anyway if you want it back, I suggest you take it up with the prototype folks. In the mean time we should probably remove all mention of :on from the code/docs as it's just confusing people

    I don't need this feature really anymore, so I would suggest as well to delete it from the rails documentation as it was really confusing.
