Question

我正在使用带有角度的谷歌地图API。在一个简单的应用程序中，左侧有一个带有大量标记的MAP，右侧有一个表格列表，其中包含有关标记的信息，每个标记有一行。在标记悬停时，我突出显示右侧悬停标记的行，下面是代码。

google.maps.event.addListener(marker, 'mouseover', function () {
            var temp_marker_name = this.marker_name;
            $scope.$apply(function () {
                $scope.active_row_name = temp_marker_name;
            });
        });
        google.maps.event.addListener(marker, 'mouseout', function () {
            $scope.$apply(function () {
                $scope.active_row_name = '';
            });
        });

所以在这里，我在标记悬停上设置名称，并根据名称，突出显示右侧的行。

现在，有一种情况是在同一位置绘制了多个标记，当我将鼠标悬停在该标记上时，它只突出显示右侧的一行。

但是我想突出显示该位置标记的所有行。所以，我想要一些东西，悬停事件将触发同一位置的所有标记，我可以创建一个名称数组然后我可以放一个条件就是突出显示行。

Downvoters为downvote添加说明，以便我改进我的问题。

Answer 1

悬停只会检测到顶部的标记。您可以做的是维护一系列标记，并在您的事件监听器中遍历此数组以获取具有相同lat lng值的标记。

编辑：获得标记列表后，对于同一位置的每个标记，您可以手动触发鼠标悬停事件。

google.maps.event.trigger(marker, 'mouseover');

通过在另一个标记的zIndex上方看到其底部的zIndex，可以使底部标记可见。

function createMarker(point, html, i, map) {
  var marker = new google.maps.Marker({
    map: map,
    position: point,
    zIndex: 0,
    draggable: true

  });
  var activeIcon, idleIcon;

  idleIcon = 'http://labs.google.com/ridefinder/images/mm_20_blue.png';

  marker.setIcon(idleIcon);

  var elem = document.getElementById('a' + i);
  if (!!elem) {
    elem.onmouseover = function() {
      marker.setIcon('http://labs.google.com/ridefinder/images/mm_20_red.png');
      marker.setZIndex(100);
    }
    elem.onmouseleave = function() {
      marker.setIcon(idleIcon);
      marker.setZIndex(0);
    }
  }
  google.maps.event.addListener(marker, 'click', function() {
    infoWindow.setContent(html);
    infoWindow.open(map, marker);

  });

  return marker;
}
