要从地图中删除所有标记，创建如下函数:

1.addMarker(location):这个函数用于在地图上添加标记

2.clearMarkers():该函数从map中移除所有标记，而不是数组中

3.setMapOnAll(map):这个函数用于在数组中添加标记信息

4.deleteMarkers():该函数通过删除对数组中所有标记的引用来删除它们。

// 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);
      }


// Sets the map on all markers in the array.
      function setMapOnAll(map) {
        for (var i = 0; i < markers.length; i++) {
          markers[i].setMap(map);
        }
      }



// Removes the markers from the map, but keeps them in the array.
  function clearMarkers() {
    setMapOnAll(null);
  }

// Deletes all markers in the array by removing references to them.
      function deleteMarkers() {
        clearMarkers();
        markers = [];
      }

您需要将map null设置为该标记。

var markersList = [];    

function removeMarkers(markersList) {
   for(var i = 0; i < markersList.length; i++) {
      markersList[i].setMap(null);
   }
}

function addMarkers() {
   var marker = new google.maps.Marker({
        position : {
            lat : 12.374,
            lng : -11.55
        },
        map : map
       });
      markersList.push(marker);
   }

我尝试了所有提出的解决方案，但当我所有的标记都在一个集群下时，没有一个对我有效。 最后我写了这个:

var markerCluster = new MarkerClusterer(map, markers,
    { imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m' });
agentsGpsData[agentGpsData.ID].CLUSTER = markerCluster;

//this did the trick
agentsGpsData[agentId].CLUSTER.clearMarkers();

换句话说，如果你在一个集群中包装标记，并想要删除所有标记，你调用:

clearMarkers();

在这里你可以找到一个如何删除标记的例子:

https://developers.google.com/maps/documentation/javascript/examples/marker-remove?hl=es

// Add 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);
}

// Sets the map on all markers in the array.
function setAllMap(map) {
  for (var i = 0; i < markers.length; i++) {
    markers[i].setMap(map);
   }
}

// Removes the markers from the map, but keeps them in the array.
function clearMarkers() {
  setAllMap(null);
}

// Deletes all markers in the array by removing references to them.
function deleteMarkers() {
  clearMarkers();
  markers = [];
}

        });
        markers.push(marker);
      }


// Sets the map on all markers in the array.
      function setMapOnAll(map) {
        for (var i = 0; i < markers.length; i++) {
          markers[i].setMap(map);
        }
      }



// Removes the markers from the map, but keeps them in the array.
  function clearMarkers() {
    setMapOnAll(null);
  }

// Deletes all markers in the array by removing references to them.
      function deleteMarkers() {
        clearMarkers();
        markers = [];
      }

for (i in markersArray) {
  markersArray[i].setMap(null);
}

只在IE上工作。

for (var i=0; i<markersArray.length; i++) {
  markersArray[i].setMap(null);
}

工作在chrome, firefox，如…
