解决方案非常简单。您可以使用方法：marker.setMap(map);。在这里，您可以定义图钉将出现在哪个地图上。
因此，如果您null使用此方法（marker.setMap(null);）进行设置，则该图钉将消失。
现在，您可以在使地图中的所有标记消失的同时编写一个函数witch。
您只需添加即可将引脚放置在数组中，并使用markers.push (your_new pin)或以下代码进行声明，例如：
// Adds a marker to the map and push to the array.
function addMarker(location) {
var marker = new google.maps.Marker({
position: location,
map: map
});
markers.push(marker);
}
这个函数可以设置或消失地图中数组的所有标记：
// Sets the map on all markers in the array.
function setMapOnAll(map) {
for (var i = 0; i < markers.length; i++) {
markers[i].setMap(map);
}
}
要消失所有标记，应使用调用函数null：
// Removes the markers from the map, but keeps them in the array.
function clearMarkers() {
setMapOnAll(null);
}
而且，要删除和消失所有标记，您应该像这样重置标记数组：
// Deletes all markers in the array by removing references to them.
function deleteMarkers() {
clearMarkers();
markers = [];
}
这是我完整的代码。这是我可以简化为的最简单的方法。
