[Solved] Google Maps Javascript positioning control maps

by


One option (use the custom pan control from this question):

function initialize() {
  var mapDiv = document.getElementById('map_canvas');
  var map = new google.maps.Map(mapDiv, {
    center: new google.maps.LatLng(39.300299, 34.471664),
    zoom: 6,
    disableDefaultUI: true,
    mapTypeControl: true,
    //mapTypeControlOptions: { style: google.maps.MapTypeControlStyle.DROPDOWN_MENU, position: google.maps.ControlPosition.RIGHT_TOP },
    mapTypeControlOptions: {
      style: google.maps.MapTypeControlStyle.DROPDOWN_MENU,
      position: google.maps.ControlPosition.LEFT_TOP
    },
    mapTypeId: google.maps.MapTypeId.TERRAIN,
    zoomControl: true,
    zoomControlOptions: {
      position: google.maps.ControlPosition.TOP_LEFT
        /*,
                index: -1 */
    },
    scaleControl: true,
    streetViewControl: false
  });
  var PanControl = new geocodezip.web.PanControl(map);
  PanControl.index = 1;
  map.controls[google.maps.ControlPosition.TOP_LEFT].push(PanControl);

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

/**

function CreateElement(tagName, properties) {
  var elem = document.createElement(tagName);
  for (var prop in properties) {
    if (prop == "style")
      elem.style.cssText = properties[prop];
    else if (prop == "class")
      elem.className = properties[prop];
    else
      elem.setAttribute(prop, properties[prop]);
  }
  return elem;
}
