javascript - Google Maps API，添加带有标签的自定义 SVG 标记

Question

我正在尝试向我的 SVG 标记添加标签，但文本相对于标记的位置有问题，反之亦然。

这是我的图标:

  var clickIcon = {
      path: 'M8,0C3.400,0,0,3.582,0,8s8,24,8,24s8-19.582,8-24S12.418,0,8,0z M8,12c-2.209,0-4-1.791-4-4   s1.791-4,4-4s4,1.791,4,4S10.209,12,8,12z',
      fillColor: myRandomColor,
      fillOpacity: 1,
      strokeColor: myRandomColor,
      strokeWeight: 1
  };

这是我添加标记的地方:

  clickMarker = new google.maps.Marker({
  position: location,
  map: map,
  animation: google.maps.Animation.DROP,
  draggable: isDraggable,
  icon: clickIcon,
  label: {
      text: labels[labelIndex++ % labels.length],
      color: 'black',
      fontSize: '15px',
      fontWeight: 'bold'
  }
  });

请注意，我只添加了相关代码，如果需要更多请告诉我。如您所见，我无法对齐标签和标记。理想情况下，我希望将它放在针圈内，但在针脚下方也可以。提前致谢。

使用 Symbol 的 labelOrigin 属性

labelOrigin

Type: Point

The origin of the label relative to the origin of the path, if label is supplied by the marker. By default, the origin is located at (0, 0). The origin is expressed in the same coordinate system as the symbol's path. This property is unused for symbols on polylines.

代码片段:

function initialize() {
  var map = new google.maps.Map(
    document.getElementById("map_canvas"), {
      center: new google.maps.LatLng(37.4419, -122.1419),
      zoom: 13,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });
  var clickIcon = {
    path: 'M8,0C3.400,0,0,3.582,0,8s8,24,8,24s8-19.582,8-24S12.418,0,8,0z M8,12c-2.209,0-4-1.791-4-4   s1.791-4,4-4s4,1.791,4,4S10.209,12,8,12z',
    fillColor: "#ff0000",
    fillOpacity: 1,
    strokeColor: "#ff0000",
    strokeWeight: 1,
    labelOrigin: new google.maps.Point(8, 10),
    anchor: new google.maps.Point(9, 35),
  };
  var clickMarker = new google.maps.Marker({
    position: map.getCenter(),
    map: map,
    // animation: google.maps.Animation.DROP,
    draggable: true,
    icon: clickIcon,
    label: {
      text: "A",
      color: 'black',
      fontSize: '15px',
      fontWeight: 'bold'
    }
  });
}
google.maps.event.addDomListener(window, "load", initialize);

body,
#map_canvas {
  height: 100%;
  width: 100%;
  margin: 0px;
  padding: 0px
