Google Maps API V3: Show the whole world

Question

How can I programmatically zoom the map so that it covers the whole world?

Answer 1

function initialize () {

var mapOptions = {
	center: new google.maps.LatLng(0, 0),
	zoom: 1,
	minZoom: 1
};

var map = new google.maps.Map(document.getElementById('map'),mapOptions );

var allowedBounds = new google.maps.LatLngBounds(
	new google.maps.LatLng(85, -180),	// top left corner of map
	new google.maps.LatLng(-85, 180)	// bottom right corner
);

var k = 5.0; 
var n = allowedBounds .getNorthEast().lat() - k;
var e = allowedBounds .getNorthEast().lng() - k;
var s = allowedBounds .getSouthWest().lat() + k;
var w = allowedBounds .getSouthWest().lng() + k;
var neNew = new google.maps.LatLng( n, e );
var swNew = new google.maps.LatLng( s, w );
boundsNew = new google.maps.LatLngBounds( swNew, neNew );
map .fitBounds(boundsNew);

}

google.maps.event.addDomListener(window, 'load', initialize);

#map {
    width: 500PX;
    height: 500px;
}

// map zoom level should be 1
