In Google Maps JavaScript API v2, Polygon had a getBounds() method, but that doesn’t exist for v3 Polygon. Here’s the solution:
if (!google.maps.Polygon.prototype.getBounds) {
google.maps.Polygon.prototype.getBounds = function() {
var bounds = new google.maps.LatLngBounds();
var paths = this.getPaths();
var path;
for (var i = 0; i < paths.getLength(); i++) {
path = paths.getAt(i);
for (var ii = 0; ii < path.getLength(); ii++) {
bounds.extend(path.getAt(ii));
}
}
return bounds;
}
}
Here, we present a simplified method:
if (!google.maps.Polygon.prototype.getBounds) {
google.maps.Polygon.prototype.getBounds=function(){
var bounds = new google.maps.LatLngBounds()
this.getPath().forEach(function(element,index){bounds.extend(element)})
return bounds
}
}
