Herb, your line:
var eventData = YAHOO.lang.JSON.parse(o.responseText)["timeline"]["events"]
Seems to call the list of event objects. What you want is the object
that has the 'events' property. I don't know how that yahoo parser
works, but I think you should be calling the data object thus:
var eventData = YAHOO.lang.JSON.parse(o.responseText)["timeline"]
then your eventData variable will contain a js object with a key
'events' and a value that is a list of event objects
As to your line:
eventSource.loadJSON(eventData["timeline"], document.location.href);
This may be superfluous, try proceeding without it. The
eventSource.loadJSON method (sources.js in the api) goes to some
lengths to derive a base url derived from document.location.href. I
don't pretend to know how this method really works, but it may be that
all you need to do is to
1. create an event source:
var eventSource = new Timeline.DefaultEventSource()
2. define your themes, bands, decorators and such;
3. create a timeline instance:
tl = Timeline.create(document.getElementById("clusTimeline"), bandInfos)
(I don't think you need: Timeline.HORIZONTAL, it's the default I believe)
4. Load your data thus:
tl.loadJSON(eventData, function(json, url) {
eventSource.loadJSON(json, url); })
I've never really understood how these methods work, but you may find
it instructive to read carefully:
Timeline.DefaultEventSource.prototype.loadJSON in sources.js
and
Timeline.loadJSON in timeline.js
You'll probably understand what's going on in there better than I
