Question

我正在使用谷歌地图api v3。在地图的中间有一个（自定义）标记标记，标记主体周围有大的透明区域。在旗帜图标下面还有另一个标记，由于死透明区域而无法访问。有没有办法将标记标记设置为点击？我找不到解决办法。

Answer 1

是的，Marker类可能有一个MarkerShape object的形状属性。这描述了Marker的可点击区域。

这是Google's Example。他们有一个自定义标志图像并调整形状，以便只能点击矩形标志部分。使用MarkerShape对象，您可以绘制圆形，重新整形或多边形形状区域。

Google示例代码段：

function setMarkers(map, locations) {
  // Add markers to the map

  // Marker sizes are expressed as a Size of X,Y
  // where the origin of the image (0,0) is located
  // in the top left of the image.

  // Origins, anchor positions and coordinates of the marker
  // increase in the X direction to the right and in
  // the Y direction down.
  var image = new google.maps.MarkerImage('images/beachflag.png',
      // This marker is 20 pixels wide by 32 pixels tall.
      new google.maps.Size(20, 32),
      // 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, 32));
  var shadow = new google.maps.MarkerImage('images/beachflag_shadow.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(37, 32),
      new google.maps.Point(0,0),
      new google.maps.Point(0, 32));
      // Shapes define the clickable region of the icon.
      // The type defines an HTML &lt;area&gt; element 'poly' which
      // traces out a polygon as a series of X,Y points. The final
      // coordinate closes the poly by connecting to the first
      // coordinate.
  var shape = {
      coord: [1, 1, 1, 20, 18, 20, 18 , 1],
      type: 'poly'
  };
  for (var i = 0; i < locations.length; i++) {
    var beach = locations[i];
    var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
    var marker = new google.maps.Marker({
        position: myLatLng,
        map: map,
        shadow: shadow,
        icon: image,
        shape: shape,
        title: beach[0],
        zIndex: beach[3]
    });
  }
}

是的，将 clickable 属性设置为 false。例如：

const newMarker = new google.maps.Marker(
          position: {
            lat: 10,
            lng: -66
          },
          clickable: false // <------
)
