First of all, you can access to the original XML node through the "_node"
attribute
of the Event object. So, IMHO, it would be a better solution to use
`this._node.description` instead of `elmt.innerHTML`. Better yet, you could
add a special attribute in your event XML node like :
<event start="..." mydata="{param1: value1, ...}">...</event>
and then, in fillInfoBubble, do something like :
eval( '(' + this._node.getAttribute('mydata') + ')' );
Finally, my personal choice would be, if you can, to seve a JSON file
directly
instead of a XML file and use loadJSON instead of loadXML. The structure is
basically the same, but you could extend your event structure directly like
in :
{start: "...", mydata: "..."}
and then, in fillInfoBubble() write the following code to access your data :
this._obj.mydata
Note that when using loadJSON, the original object is stored in the `_obj`
attribute rather
than `_node` which I personally find a bit confusing.
Hope this helps,
Adrien.
