Create a click event to points

[Kafusna]

this plugin have some click point event? how can i use this?

[Boityakov]

you must use Custom layer example from README.md and add next code

this.setData = function (data) {
  this.markers = data;
  this.needRedraw();
};
this.boundsToQuery = function(bounds) {
  return {
    lat: bounds.getSouthWest().lat,
    lng: bounds.getSouthWest().lng,
    width: bounds.getNorthEast().lat - bounds.getSouthWest().lat,
    height: bounds.getNorthEast().lng - bounds.getSouthWest().lng
  };
};
this._isPointInsideBounds = function (point, bounds) {
  return (
    (point.lat >= bounds.lat) && (point.lat <= bounds.lat + bounds.width) &&
    (point.lng >= bounds.lng) && (point.lng <= bounds.lng + bounds.height)
  );
};
this.getEvents = function () {
  var events = {
    resize: this._onLayerDidResize,
    moveend: this._onLayerDidMove,
    zoom: this._onLayerDidMove,
    click: this._onLayerDidMouse,
    mousemove: this._onLayerDidMouse
  };
  if (this._map.options.zoomAnimation && L.Browser.any3d) {
    events.zoomanim =  this._animateZoom;
  }
  return events;
};
this._onLayerDidMouse = function(e) {
  var j = e.containerPoint;
  var t = e.type;
  var bounds = L.latLngBounds(this._map.containerPointToLatLng(j.add(L.point(3,3))), 
  this._map.containerPointToLatLng(j.subtract(L.point(3,3))))
  var points = this.retrieveInBounds(this.boundsToQuery(bounds));
  if (points.length > 0) {
    if (t == 'mousemove') {
      this.hoverInPoints(points, e);
    }
    if (t == 'click') {
      this.clickedPoints(points, e);
    }
  } else {
    this.hoverOutPoints(e);
  }
};
this.clickedPoints = function(points, e) {
  var text = "You clicked on the point Latitude["+ points[0].lat + "] Longitude["+ points[0].lng + "]";
  alert(text);
};

this.hoverInPoints = function(points, e) {
  var text = "You hovered on the point Latitude["+ points[0].lat + "] Longitude["+ points[0].lng + "]";
  console.log(text);
};
this.hoverOutPoints = function(e) {
 //TODO
}

@maiti Do you have a working example of this you could share?
