javascript - 删除特定标记 APIv3

Question

如何删除谷歌地图中的特定标记？我尝试了下面的代码，但收到 TypeError:marker[1] is undefined 错误。如果没有 [1]，它只会删除第一个标记。

google.maps.event.addDomListener(deletemark, 'click', function() {
          marker[1].setMap(null);
});
}

(来自评论，稍作编辑)这就是我创建标记以及标记的经纬度数组的方式

var locations = [ [56.066877,21.069274], [55.279849,26.048155] ]; // removed "hanging comma"
for (i = 0; i < locations.length; i++) 
{
  marker = new MarkerWithLabel({
    position: new google.maps.LatLng(locations[i][0], locations[i][1]), 
    map: map // removed "hanging comma"
  });
} // added missing close bracket

尝试使用数组来存储标记，

var markerArray=[];
var locations = [ [56.066877,21.069274], [55.279849,26.048155] ];
for (i = 0; i < locations.length; i++) 
{
 marker = new MarkerWithLabel({
 position: new google.maps.LatLng(locations[i][0], locations[i][1]), 
 map: map // removed "hanging comma"
 });
markerArray.push(marker);
} /

以及删除标记，

function deleteMarkers() {
  if (markersArray) {
  for (i in markersArray) {
   markersArray[i].setMap(null);
  }
markersArray.length = 0;
}
}
