Hi,
I'm trying to customize this map:
http://gmaps-samples.googlecode.com/svn/trunk/poly/mymapstoolbar.html.
Specifically, what I need is to be able to save a polyline or polygon
the user draws on the map, and display it on another map elsewhere on
the site.
I started inside the startShape() function, where:
startDrawing(polygon, "Shape " + (++shapeCounter_), function() {
var cell = this;
var area = polygon.getArea();
cell.innerHTML = (Math.round(area / 10000) / 100) + "km<sup>2</
sup>";
}, color);
I changed the above to:
startDrawing(polygon, "Shape " + (++shapeCounter_), function() {
var cell = this;
var count = polygon.getVertexCount();
var vertices = new Array();
for (i=0;i<count;i++) {
vertices[i] = polygon.getVertex(i);
cell.innerHTML = vertices;
}, color);
The idea was that instead of displaying the area of the polygon, it
would give the vertices of the polygon, which I could save to a
database and redraw later on another map. But this approach gives me
nothing. I can use getVertex() on a specific vertex (1, 2, 3, etc.),
which outputs a value, but the loop doesn't give me anything.
Can someone shed some light on what I might be doing wrong? Am I
putting the loop in the wrong place/function? Or is the loop wrong
altogether, should I be doing something else?
Thanks,
Precar.
