Hide/show polygon

[Grapefruit]

I've drawed 2 polygons on my map;
- poly
- poly1

With the button 'Toggle Visibility' I want to hide/show the polygon
'poly'.

I've seen the examples, but they're all for API V2. I need something
for V3.

I've tried some things with hide() but I'm not good with JS so I can't
make it on my own without some help...

What do I have to do to hide/show the polygons? Or isn't it possible
and do I have to stick to V2?

.setMap(null);

What could possibly be the reasoning for having polygons that cannot
be removed after being added?

.setMap(null) is good if you want to remove the polygon. But is there
any way to hide the polyline/gon?
I mean the equivalent of setVisible(true/false) for marker class.

Thank You

For that, you can add your own methods. See:
"Hiding and Showing an Overlay" in
http://code.google.com/apis/maps/documentation/v3/overlays.html#Polygons

I use Maps as a map for my company, with different area's of
customers. I want to select different area's therefor.

I've tried this http://code.google.com/intl/nl/apis/maps/documentation/v3/overlays.html#HideShow
but I don't know how to translate this to my map and to my polygons...

wait, .setMap(null); works great! Thanks

This is working, but only when:

google.maps.event.addListener(poly, 'click', function() {
poly.setMap(null);
});

I want to let it disappear when I click on a button outside of the
map.
What do I need to put in the onClick=""? I can't figure it out...

I've tried onClick="remov()"
with
function remov() {
poly.setMap(null);
}

but then nothing is happening...
Yes, i'm a JS noob :)

1. This is not a forum for basic javascript.

2. Please read and follow the group's posting guidelines:

Yes, I know, but I can't find these things in tutorials (only simple
things with alert () )
I don't know how to refer to the google.maps. A simple link to a
tutorial is enough, I want to do it myself :)

My link is http://www.andorvb.nl/test2.html
If you click on the polygon, it disappears, just like it has to. When
you click on the other one, it appears again. But I want to do that
with the Remove!-link :)

It's about scope. Unnest your functions and make your var map global:

Thanks, that was the missing key.

BTW, is there a contextmenu available for V3?
