Question

我有一组标记以缩放级别15添加到地图中。标记lat和lng当前设置为小数点后第6位。

当我放大或缩小标记位置时，它们会移出正确的位置。我是否需要在每个缩放级别删除和重绘标记？我需要提高我的坐标的准确性吗？这让我发疯了......

我正在创建我的标记：

function createMarker(data, type) 
{
  var posn = new google.maps.LatLng(data.lat,data.lng);
  var title = data.title;
  var image,shadow,shape;
  if (data.typeId === '101') {
      image = new google.maps.MarkerImage('/api/v1.0/map/images/buildings.png',
      // This marker is 20 pixels wide by 32 pixels tall.
      new google.maps.Size(24, 28),
      // The origin for this image is 0,0.
      new google.maps.Point(0,0),
      // The anchor for this image is the base of the flagpole at 0,32.
      new google.maps.Point(0, 28));
    shadow = new google.maps.MarkerImage('/api/v1.0/map/images/shadow-buildings.png',
      // The shadow image is larger in the horizontal dimension
      // while the position and offset are the same as for the main image.
      new google.maps.Size(39, 28),
      new google.maps.Point(0,0),
      new google.maps.Point(0, 28));

  } 
  var markerOptions = {
    position: posn,
    title: title,
    shadow: shadow,
    icon: image
};

var marker = new google.maps.Marker(markerOptions);

    // could add event handler here

    //add marker to array for latter use
    if (type === 'building') {
       buildingMarkers.push(marker);
    }
}

当标记放置在纬度/经度位置时，您不必添加/删除标记。

也许某些代码可能会帮助我们解决这个问题。
