google maps insertAt

In V3 of the javascript api for the polygon array there is a func开发者_Python百科tion insertAt(), does anyone have an example of how this is used?

You need to create your MVCArray object:

pathCoords = new google.maps.MVCArray();

Then set up your map:

myPoly = new google.maps.Polyline({
    path: pathCoords,
    strokeColor: '#000000',
    strokeOpacity: 1,
    strokeWeight: 2
});
myPoly.setMap(map);

You can then insert latLng objects:

myPoly.getPath().insertAt(pathCoordinates.length, latLng);
