Re: Progress event spec

For something like an HTTP connection where you take a couple of seconds to establish the connection it would be useful to fire a progress event with zero bytes loaded. In the case of doing this for a connection where you don't know the length, this will be indistinguishable from a (now presumably completed) zero-length transfer. But since the transfer has presumably finished, what kind of UA would actually fire such a pointless event? It already *must* fire the load event, which you can trap to note that your loading is finished. JCD: I have already answered about the "load" event, which I believe is disconnected (connected to the loading of the element, not to the loading of the resource when the xlink:href is updated by scripting or animation). So the assumption behind the above combination is that it is a justifiable hack. I certainly haven't seen any use case for the zero-length transfer to fire a progress event - if there is one, then of course this hack is not good enough. JCD: I want to be able to start an animation on "beginning of load", and stop it on "end of load", and just use the simple syntax of an event in a begin/end attribute. This is easy, well-known and liked by authors, why do you want to remove that syntax facility ? The SVG working group is working on Media Access Events. Did you think of reading that spec and checking if there are interactions ? Would it be meaningful to merge the two ? I might have a more interesting opinion after having *actually* read it instead of just thinking about it :) JCD: Was that too English ? If so I apologize. Did you read the MAE spec and did you find interactions and should we merge the two specs ? Thanks JC -- Jean-Claude Dufourd - Chief Scientist, Streamezzo 21, av.
