Check if marker is in view (map) - mapbox

问题:

I want to check if marker is on mapview or out of the map. I am putting marker of the map and not able to check if it on currentView or not. I have tried below code. this.map.getBounds().contains(e.layer.getLatLng()); but it is returning me true. map is returning its old lat lng i.e bounds (I think so)

回答1:

map.getBounds().contains(myMarker.getLatLng())

• map.getBounds(): Returns the LatLngBounds of the current map view.

• latLngBounds.contains(): Returns true if the rectangle contains the given point.

• myMarker.getLatLng(): Returns the current geographical position of the marker.

回答2:

I use custom function:

function inBounds(point, bounds) {
  var lng = (point.lng - bounds._ne.lng) * (point.lng - bounds._sw.lng) < 0;
  var lat = (point.lat - bounds._ne.lat) * (point.lat - bounds._sw.lat) < 0;
  return lng && lat;
}
