我正在尝试删除像这样初始化的标记:

marker = new google.maps.Marker({
    position: latLng,
    map: map,
    draggable: true,
    animation: google.maps.Animation.DROP,
    title: 'Marker 1',
    icon: redPin
});

google.maps.event.addListener(marker, "click", function() {
    showMarkerDialog(marker.position, "marker");
});

google.maps.event.addListener(marker, "dblclick", function() {
    // Add a alert: Are you sure you want to remove this marker?

    map.removeOverlay(marker);
});

一切都很完美,除了当我双击它以删除我在错误控制台上得到的是这样的:

TypeError:Object#没有方法'removeOverlay'

我究竟做错了什么？
