Is it possible to zoom with googles geocode api?

I can't get my map to zoom in, I tried to edit the zoom property with in the options object, like the normal google maps API but it doesn't work. Any ideas?

Yes, it´s possible.
For example using zoom attribute as follows:
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 8,
center: {lat: -34.397, lng: 150.644}
});
var geocoder = new google.maps.Geocoder();
document.getElementById('submit').addEventListener('click', function() {
geocodeAddress(geocoder, map);
});
}

Can Google Maps API v.3 work for Mars?

I am playing with writing a little javascript solution that would take place on mars. I would love to have the output result in a google map of a lat and long on Mars. Any thoughts? Can the following concept BE called for a location on the red planet?
`map = new google.maps.Map();`
I see stuff in the API that indicates this at lease WAS doable in v.2, but I don't know if that survived, and can't seem to scare anything relevant up to tell me if this is a possibility or a dead end.
For Earth, this looks straight forward enough.
var map;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: -34.397, lng: 150.644},
zoom: 8
});
var markerTest = {lat: -34.397, lng: 150.644};
var marker = new google.maps.Marker({
position: markerTest,
map: map
});
}
Here's an Fiddle example: https://jsfiddle.net/chakra5/qx3r12xk/
Many thanks in advance for any and all brainstorming.

Google maps displays many versions of same map upon zooming out

I am trying to zoom out of the google map,this is what happens:
How can I stop this kind of behaviour from occuring?

Include the minZoom property in your map options:
...
var mapOptions = {
minZoom: 2
}
map = new google.maps.Map( document.getElementById( 'map-canvas' ), mapOptions );
...
This will limit the amount that user will be able to zoom out, which will prevent the map from repeating.
More info: https://developers.google.com/maps/documentation/javascript/reference

Set maxZoom property for map .
var mapOptions = {
zoom: 11,
center: tokyo,
mapTypeId: google.maps.MapTypeId.HYBRID
}
map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
google.maps.event.addListener(map, 'click', showMaxZoom);
Look at here : https://developers.google.com/maps/documentation/javascript/maxzoom

Google Map KML layer - click event return ZERO_RESULTS

I am working with the Google Maps KML layer click event.
I am using this code:
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(41.875696, -87.624207),
zoom: 11,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var ctaLayer = new google.maps.KmlLayer('https://sites.google.com/site/anoopkml123/kml/ab9Plan0520.kmz');
ctaLayer.setMap(map);
google.maps.event.addListener(ctaLayer, 'click', function(kmlEvent) {
alert(kmlEvent.featureData.name);
});
}
Sometimes alert(kmlEvent.featureData.name) shows a number but sometimes it's 'undefined'.
Sometimes obj.featuredData.id is null (ZERO_RESULTS status is in status field).

Re-created your code in a fiddle: http://jsfiddle.net/mdares/TAfys/
I cannot replicate the issue you are having. Can you provide an example given the above link of where it fails? Is this possibly browser specific? Finally - is there any additional code you haven't posted which might be the cause? My code is unchanged from yours as you posted, but I am curious if you are also doing other things:
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(41.875696, -87.624207),
zoom: 11,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var ctaLayer = new google.maps.KmlLayer('https://sites.google.com/site/anoopkml123/kml/ab9Plan0520.kmz');
ctaLayer.setMap(map);
google.maps.event.addListener(ctaLayer, 'click', function (kmlEvent) {
alert(kmlEvent.featureData.name);
});
}

Google Maps buttons not showing

I have a problem with google maps. When i firstly embeeded iframe to my page on ipad i saw buttons like streetview under the map. When i switched maps to be generated from system data, and rendering using javascript api buttons are gone?
Is there a way to show them again, is it just an options that needs to be added to map or buttons only work when using iframe?
var map;
var service;
var infowindow;
function initializeMap() {
var slocation = new google.maps.LatLng(x,y);
map = new google.maps.Map(document.getElementById('map'), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: slocation,
zoom: 15
});
var infowindow = new google.maps.InfoWindow({
content: 'example content'
});
var marker = new google.maps.Marker({
position: slocation,
map: map,
title: ' example title'
});
infowindow.open(map, marker);
}
the buttons that i want to achive are http://imageshack.us/photo/my-images/43/buttonsuv.png/

In your code, add this option streetViewControl: true
map = new google.maps.Map(document.getElementById('map'), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: slocation,
zoom: 15,
streetViewControl: true
});
Have a look at this, it summarises all of the street view options.
UPDATE
After the question update, I realise you want your custom image on the street view icon.
That's not possible.
One workaround is to define a custom control on the map, and link events to it with the streetview events.
I've never done it, however you might want to have a look at this
