- pgFetch() is called with the notify parameter set to this.name to send a user event to the object that called the function.
- pgFetch() is called with the loadPage parameter set to a section tag of the XML called <theMenu>. Since this tag contains only string data, pgFetch() will return only the string (or in this case the HTML boilerplate code). Otherwise, if <theMenu> contained other tags and functions definitions, the return from pgFetch() would've been an XML document. If one of the sub-tags was <theCode>, then it could be accessed as
[e.data]["theCode"]
in the user event function.
