Hi guys!
i know prototype can create custom events and can subscribe to it, but is
there already a library for this?
thanks!

Here is what I''ve been using for custom events in my projects.
It is pretty straight forward and small.
http://www.brandonaaron.net/prototype/src/event.custom.js
You create an event like this:
var onMyEvent = new Event.Custom(''myEvent''[, someObject ||
window]);
The first param is the name of the event, it defaults to
''customEvent''. The second param is global scope correction for
all
observers. It defaults to window.
Then you can attach observers to it like this:
onMyEvent.observe(function(event[, extra, params]) { /*...*/ }[,
override scope || event scope ]);
You can detach an observer by replacing observe in the previous
example with stopObserving. I would suggest using the scope override
instead of bind to properly stopObserving functions without having to
create handlers for your observers.
You can fire the event like this:
onMyEvent.fire(eventObject[, param1, param2 /*... */]);
The eventObject is something you would create ... by default it will
contain a name property and has the name of the event when you created
it. The fire method can take any number of extra params that will be
passed onto the observers.
You can unsubscribe all observers by calling onMyEvent.unsubscribeAll()
Let me know if you use it and if it works for you. I just recently
rewrote it ... so let me know if you run into any bugs.

This seems like a Good Thing :) I think it would gain more acclaim with just a slight test-code page *hint hint* Andreas On Aug 18, 2006, at 15:34 , Brandon Aaron wrote:> Here is what I''ve been using for custom events in my projects. > It is pretty straight forward and small. > http://www.brandonaaron.net/prototype/src/event.custom.js > > You create an event like this: > > var onMyEvent = new Event.Custom(''myEvent''[, someObject || window]); > > The first param is the name of the event, it defaults to > ''customEvent''.

You can also use my EventPublisher class I posted here several months ago (attached .txt file)...

Yeah unit tests/test page coming in a week or so. I''ll post it up on my site once it is ready. Actually I''ve made some changes (backwards compatible of course) to the Event object that I''ll most likely post up at the same time. Such as scope correction/override, extra params, stopObserving works with anonymous functions and automatic event extension with event methods. I''ve been using Event.Custom and updates to the Event object for a recent project, working out the bugs and making sure it works properly. I''ll most likely post it up in about a week.
