How to add multiple polygons to a (Google) map?

How do i Add and Remove polygons on a Google Map (version 3)?

• I'm trying to show and remove polygons onto a google map - using v3 of the API. In my javascript, i've already got an MVCArray of some custom Lat-Longs. What I'm stuck trying to figure out is how to add these polys and then (based upon some other javascript event / user experience feedback .. like clicking on a poly (that has been rendered) ... that poly will be removed. Can someone help? Code or links to examples? I'm struggling to find some examples .. most of them usually goto some v2 code.. cheers :)

• Answer:

  In the API docs, there are a couple of simple examples of http://code.google.com/apis/maps/documentation/javascript/overlays.html#Polygons. Here's the initialize() function from the simple http://code.google.com/apis/maps/documentation/javascript/examples/polygon-simple.html example with the addition of adding an event listener to remove the polygon when clicked. function initialize() { var myLatLng = new google.maps.LatLng(24.886436490787712, -70.2685546875); var myOptions = { zoom: 5, center: myLatLng, mapTypeId: google.maps.MapTypeId.TERRAIN }; var bermudaTriangle; var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); var triangleCoords = [ new google.maps.LatLng(25.774252, -80.190262), new google.maps.LatLng(18.466465, -66.118292), new google.maps.LatLng(32.321384, -64.75737), new google.maps.LatLng(25.774252, -80.190262) ]; // Construct the polygon bermudaTriangle = new google.maps.Polygon({ paths: triangleCoords, strokeColor: "#FF0000", strokeOpacity: 0.8, strokeWeight: 2, fillColor: "#FF0000", fillOpacity: 0.35 }); bermudaTriangle.setMap(map); // add an event listener google.maps.event.addListener(bermudaTriangle, 'click', function() { this.setMap(null); }); }
