Leaflet 删除图层后，不会删除在传单.draw上绘制的标记

我创建了一个简单的应用程序来添加使用传单绘制点。如果用户取消取消对话框，则将删除绘制的图层。但是，当绘制下一个标记时，先前取消的标记将再次出现。下面是代码的图片：

// Create Leaflet Draw Control for the draw tools and toolbox
var drawControl = new L.Control.Draw({
  draw : {
    polygon : false,
    polyline : false,
    rectangle : false,
    circle : false,
    circlemarker: false
  },
  edit : false,
  remove: false
});

// Boolean global variable used to control visiblity
var controlOnMap = false;

// Create variable for Leaflet.draw features
var drawnItems = new L.FeatureGroup();

// Function to add the draw control to the map to start editin
function startEdits(){
  if(controlOnMap == true){
    map.removeControl(drawControl);
    controlOnMap = false;
  }
  map.addControl(drawControl);
  controlOnMap = true;
};

// Function to remove the draw control from the map
function stopEdits(){
  if(controlOnMap == true){
    map.removeControl(drawControl);
    controlOnMap = false;
  }else{
    alert("Edition mode is already stopped")
  };
};

// Use the jQuery UI dialog to create a dialog and set options
var dialog = $("#dialog").dialog({
  autoOpen: false,
  height: 600,
  width: 500,
  modal: true,
  position: {
    my: "center center",
    at: "center center",
    of: "#map"
  },
  buttons: {
    "Add": setData,
    "Cancel": function() {
      dialog.dialog("close");
      map.removeLayer(drawnItems);
    }
  },
  close: function() {
    dialog.dialog("close");
    map.removeLayer(drawnItems);
  }
});

是否有删除绘制的特征或类似特征的功能？

您还必须清除

drawnItems

组：

drawnItems.clearLayers();
map.removeLayer(drawnItems);

较新的绘图库是：

刚才我找到了这个解决方案：

    drawnItems.eachLayer(
        function(l){
            drawnItems.removeLayer(l);
    });

但福尔克设计公司的答案更为奇特。谢谢大家!
