Check whether or not a point is in a polygon (Google Maps API)

问题

So I have a map here

How can I, using Google Maps API, detect whether or not a given coordinate is within that polygon? Is that possible?

Thanks in advance.

Yes it is possible. See this function: http://github.com/tparkin/Google-Maps-Point-in-Polygon

Google provides one already

  var bermudaTriangle = new google.maps.Polygon({
    paths: [
      new google.maps.LatLng(25.774, -80.190),
      new google.maps.LatLng(18.466, -66.118),
      new google.maps.LatLng(32.321, -64.757)
    ]
  });

  google.maps.event.addListener(map, 'click', function(event) {
    console.log(google.maps.geometry.poly.containsLocation(event.latLng, bermudaTriangle));
  });
