我正在尝试创建一个标记可拖动的地图，并且它可以缓冲移动。与这个问题所处理的非常相似（几乎相同），在我的情况下，我没有使用 Mapbox.js 只使用普通传单。我目前的代码是：
//add marker that is draggable
var marker = L.marker(new L.LatLng(39.75621, -104.99404), {
draggable: true});
//add marker popup
marker.bindPopup('This marker is draggable! Move it around to see what locales are in your "area of walkability".');
marker.addTo(map);
//remove old buffers (used when marker is dragged)
function removeBuff() {
map.removeLayer(buff);
};
//create buffer (used when the marker is dragged)
function updateBuffer() {
//Make the marker a feature
var pointMarker = marker.toGeoJSON();
//buffer the marker geoJSON feature
var buffered = turf.buffer(pointMarker, 1, 'miles');
//add buffer to the map. Note: no "var" before "buff" makes it a global variable and usable within the removeBuff() function.
buff = turf.featurecollection([buffered]);
L.geoJson(buff).addTo(map);
};
marker.on('drag', function () {
removeBuff(), updateBuffer()
});
updateBuffer();
这给了我一个缓冲区并允许我拖动点和缓冲区，但是，所有以前的缓冲区都保留在地图中。
我做了一些更改以替换该问题中的 mapbox.js 函数，所以我的猜测是这可能是原因。
