Obviously there is some confusion here.. or Raymond is messing with me..
Okay..
With DynAPI 2 I could do the following:
el = new EventListener(target); // instantiate an event listener object
el.onScroll=function(e){ //assign a function to the event listener object
//whatever
}
scrollbar.addEventListsner(el); // add the event listener object to a
dynlayer
and elsewhere
scrollbar.invokeEvent("scroll"); // invoke the custom event added to the
event object
Please hold off on the sarcasm here.
I am trying to make an effort to understand.
How would I do the above without the eventListener object..
i.e.; assign the target
define the _CUSTOM_ event type
invoke the custom event type.
As for my other question.. the sarcasm really was uncalled for.
blarg = {
onBlarg : function(e){
some code;
},
doBlarg : function(what){
some more code;
}
}
Is completely unfamiliar syntax to me.
I had never seen such syntax until it popped up in the DynAPI.
I wish to understand this syntax.
Please bear with me..
I was very new to JavaScript when I discovered DynAPI v1.
Many of the techniques and concepts I use in any JavaScript project is
heavily coloured
what I learned and observed working with the DynAPI.
While I am now a competent JavaScript programmer, there
are still some things I would never want to (and have never done) without
the DynAPI..
such as complex event hierarchies
