Tane, load your page in Firefox with Firebug enabled. Open the Firebug pane
and click Script, then turn on Options/Break on All Errors. Now do your
address lookup.
Firebug will stop on your line with the error. Look at what is displayed in
the Watch window. Observe that "this" is the Window object. Not what you
expected, is it? :-)
You need to use a closure here. In your searchAddress function, save a
reference to "this" in a local variable and then use that variable inside
the geocoder callback function.
Another comment or two: You are using the name "GMap2" to mean three
different things! First is the GMap2 object that the Google Maps API
defines. Second is your GMap2() plugin method in line 100. Third is the
GMap2 property that you are adding to the DOM element in line 43. That's a
bit confusing.
Part of your code uses each() to iterate over the jQuery object, and part of
it uses [0] assuming that there is only a single DOM element in the jQuery
object. If you require an ID selector, e.g. $('#myMap') there will be only a
single DOM element anyway, but it would probably be good to stick with one
approach or the other for clarity.
Also, I'm not sure why you create the jQuery.gmapp object for your functions
and then assign them into the jQuery.fn object. Why not just assign them
into jQuery.fn directly? Nothing wrong with the way you're doing it, it just
seems like an unnecessary step.
I didn't look at the code in more detail than that.
Hope that helps!
