Question

I have a google maps api v3, which uses “The Di Lab”‘s plugin for polygon drawing:

http://www.the-di-lab.com/?p=219

And then uses tparkins plugin for raycasting.

https://github.com/tparkin/Google-Maps-Point-in-Polygon

However, I need to access the polygon object from the polygon plugin. The section in the polygon plugin that actually plots the Polygon on the map is:

this.polygonObj= new google.maps.Polygon({
                paths: this.coords,
                strokeColor: "#FF0000",
                strokeOpacity: 0.8,
                strokeWeight: 2,
                fillColor: "#FF0000",
                fillOpacity: 0.35,
                map:this.map
});

And I would create the map with:

var creator = new PolygonCreator(map);

I then have to do the point in polygon via calling:

var isWithinPolygon = polygonObj.containsLatLng("52,0");

So for example:

var coordinate = new google.maps.LatLng(40,90);                                                                                                                                                                                                       
var polygon = new google.maps.Polygon([], "#000000", 1, 1, "#336699", 0.3);
var isWithinPolygon = polygon.containsLatLng(coordinate);

Basically all I need is the polygon object from the first script. The two javascript files are below:

http://80.229.168.62/guild_service/server/js/polygon.min.js

http://80.229.168.62/guild_service/server/js/latlngcontains.js

The page running the scripts is:

If you are creating the Polygon via the creator.pen.drawPloygon() (no that’s not a typo on my part–the function really is spelled that way in polygon.min.js), then you should be able to retrieve it from creator.pen.polygon.getPolygonObj().
