How to find current zoom level in a Google Map?

Question

How do I find the current zoom level when loading or clicking a Google map?

um, [`Map.getZoom()`](http://code.google.com/apis/maps/documentation/javascript/reference.html)? — Pekka, Jun 17 '11 at 12:28

If you have a map object like this:

var mapObject = new google.maps.Map(document.getElementById("map"), _mapOptions);

use

mapObject.getZoom();

If you are using google maps api2, then you have to do it like this: `map.getCameraPosition().zoom` – AlvaroSantisteban Jul 30 '14 at 14:42

Use this code:

float zoomlevel = mMap.getCameraPosition().zoom;

If you need to get zoom on change

google.maps.event.addListener(map, 'zoom_changed', function() {
    var zoom = map.getZoom();
    console.log(zoom);
});

I got it using:

console.log(this.map.zoom);

html:

<agm-map (mapReady)="onMapReady($event)">

TS:

onMapReady(map) {
 this.map = map;
}
