How to get LatLngBounds of feature polygon geometry in google maps v3?

Question

I have a lot of polygonal features loaded with loadGeoJson and I\'d like to get the latLngBounds of each. Do I need to write a function that iterates through every lat long

Answer 1

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();
        this.getPath().forEach(function (element, index) { bounds.extend(element); });
        return bounds;
    }
}
