使用javascript,如何更改leaflet.draw"废纸篓"按钮以删除已绘制并自动保存的所有多边形.下面是我实现的代码,但它是一个完整的黑客.它删除了活动多边形,但是当我在控制台中出现错误时删除一个对象后,当我单击"垃圾桶"图标时NotFoundError: Node was not found,TypeError: this._deletedLayers is null

map.on('draw:editstart', function (e) {
            if(e.handler == 'remove' && typeof drawnItem != 'undefined' && drawnItem !== null){
                if(window.console) window.console.log('Drawing deleted...');
                if(typeof drawnItem != 'undefined' && drawnItem !== null){
                    drawnItems.removeLayer(drawnItem);
                }
                $('.leaflet-draw.leaflet-control .leaflet-draw-actions').hide();
                $('.leaflet-popup-pane .leaflet-draw-tooltip').remove();
            }
        });

我的玩笑测试出错了，但我的应用程序可以转换（webpack）并且没有错误地运行。我最近确实切换到 babel-preset-env 但我仍然遇到同样的错误。

相关的 package.json：

"jest": "^20.0.4",
"jest-fetch-mock": "^1.0.8",
"babel-core": "^6.22.1",
"babel-jest": "^20.0.3",
"babel-preset-es2015": "^6.22.0",
"babel-preset-stage-0": "^6.22.0",

.babelrc

{
  "presets": ["es2015", "stage-0"],
  "plugins": [
    ["inferno", {"imports": true}],
    ["transform-es2015-classes", {"loose": true}]
  ],
  "env": {
    "test": {
      "presets": ["es2015", "stage-0"]
    }
  }
}
