Google maps - how to find a marker in a marker array?

Question

How to check if google map marker is in marker array?
Even after that markersArray.push(marker); condition (marker in markersArray) is false.

Answer 1

First, (marker in markersArray) is incorrect, since in does not look for elements in the array.
He is looking for properties.

The way it worked for me was

 for (var i=0; i<markersArray.length; i++) { if (markersArray[i].getPosition().equals(marker.getPosition())) { ... 

This works as long as you only need to compare marker coordinates.
We use here the .lequals operator of the LatLng class.

Answer 2

You have to iterate over the array to check the marker.

 for (var i=0; i<markersArray.length; i++) { if (markersArray[i] === marker) { //doSomething... break; } } 

Answer 3

 var marker = new google.maps.Marker({ icon:icon, position: position, map: map }); 

Tokens have their own identifier. You can get this id

 var marker_id = marker.__gm_id; 

and then get a marker on the map

 map.Hb.qa[marker_id]; 

Answer 4

 markersArray.indexOf(marker) > -1
