google map zoom out limit [duplicate]

Question

How do I set zoom out limit on the map, it currently lets me zoom out too far to the point that I see multiple world maps:

JS:

var map;  var all_coor = <?php echo json_encode($addresses); ?>; var dub = <?php echo json_encode($testadd); ?>;  function initialize() { var MainLatlng = new google.maps.LatLng(-74.337724,-49.69693);    var mapOptions = {     zoom: 7,     center: new google.maps.LatLng(31.386692,-12.700747)   };   map = new google.maps.Map(document.getElementById('map-canvas'),       mapOptions);   var markerr = new google.maps.Marker({       position: MainLatlng ,       map: map,       title: 'Main',       animation: google.maps.Animation.DROP   });  for (var t = 0, llen = dub.length; t < llen; t++) {      var marker = new google.maps.Marker({       position: new google.maps.LatLng(dub[t]['lat'], dub[t]['long']),       map: map,       title: dub[t]['title']     });  }  }   google.maps.event.addDomListener(window, 'load', initialize); 

HTML:

<div id="map-container" style="height: 500px;"> <div id="map-canvas" style="width: 100%; height: 100%"></div> </div> 

1.How can I set a zoom out limit for the map to render properly?

It's been added to the api, you can just set that option directly on the map object:

  map.setOptions({ minZoom: 5, maxZoom: 15 });
