i am using Google Drawing tools for drawing polygon/rectangle on google maps, now i need to show markers that falls inside the drawn polygon and for that i am using geometry.poly.containsLocation method which takes a point(latLng) and an array of polygon points. if i use maps.polygon I can get polygon points via poly.getPath() but because i am using Google Drawing tools which uses maps.drawing.DrawingManager/google.maps.drawing.OverlayType.POLYGON so not sure how to find points here. Thanks
var drawingManager = new google.maps.drawing.DrawingManager({
drawingMode: google.maps.drawing.OverlayType.POLYGON,
drawingControl: true,
drawingControlOptions: {
position: google.maps.ControlPosition.TOP_CENTER,
drawingModes: [
google.maps.drawing.OverlayType.MARKER,
google.maps.drawing.OverlayType.CIRCLE,
google.maps.drawing.OverlayType.POLYGON,
google.maps.drawing.OverlayType.POLYLINE,
google.maps.drawing.OverlayType.RECTANGLE
]
},
markerOptions: {
icon: 'images/car-icon.png'
},
circleOptions: {
fillColor: '#ffff00',
fillOpacity: 1,
strokeWeight: 5,
clickable: false,
editable: true,
zIndex: 1
},
polygonOptions: {
fillColor: '#BCDCF9',
fillOpacity: 0.5,
strokeWeight: 2,
strokeColor:'#57ACF9',
clickable: false,
editable: false,
zIndex: 1
}
});
console.log(drawingManager)
drawingManager.setMap(map)
google.maps.event.addListener(drawingManager, 'polygoncomplete', function (polygon) {
// assuming you want the points in a div with id="info"
document.getElementById('info').innerHTML += "polygon points:" + "<br>";
for (var i = 0; i < polygon.getPath().getLength(); i++) {
document.getElementById('info').innerHTML += polygon.getPath().getAt(i).toUrlValue(6) + "<br>";
}
});

var geocoder;
var map;
var polygonArray = [];
function initialize() {
map = new google.maps.Map(
document.getElementById("map_canvas"), {
center: new google.maps.LatLng(37.4419, -122.1419),
