Question

如何将zoomControl选项和panControl定位彼此相邻？谢谢你...

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,
        panControl: true,
        panControlOptions: { position: google.maps.ControlPosition.LEFT_TOP},
        zoomControl: true,
        zoomControlOptions: { style: google.maps.ZoomControlStyle.BIG, position: google.maps.ControlPosition.LEFT_TOP },
        scaleControl: true,
    });

一个选项（使用this question中的自定义平移控件）：

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);
