与我的代码,每次你点击地图时出现几个标记。如何删除谷歌地图api标记后设置
我想只是一个单一的标记,每次点击删除上一个标记,并设置新的标记的纬度/ lng到新位置。
这里是我的代码:
var map;
var markers = [];
function initMap() {
var aa = {lat: 32.3896651, lng: 48.3791718};
map = new google.maps.Map(document.getElementById('map'), {
zoom: 12,
center: aa
});
// This event listener will call addMarker() when the map is clicked.
map.addListener('click', function(event) {
addMarker(event.latLng);
document.getElementById("la").value = event.latLng.lat();
document.getElementById("lo").value = event.latLng.lng();
});
}
// Adds a marker to the map and push to the array.
function addMarker(location) {
var marker = new google.maps.Marker({
position: location,
flat: false,
map: map,
draggable: true
});
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);
}
// Shows any markers currently in the array.
function showMarkers() {
setMapOnAll(map);
}
// Deletes all markers in the array by removing references to them.
function deleteMarkers() {
clearMarkers();
markers = [];
}
