传单错误：this.callInitHooks 不是函数错误？
我正在使用传单 v1.5.1。Chrome的错误是：
leaflet.js:5 Uncaught TypeError: this.callInitHooks is not a function at Object.i [as Marker] (leaflet.js:5) at map1Rose2.php:77
以下是将在 Chrome 中重现该问题的最少代码。我没有看到该功能有问题。错误出现在 . 我已经用尽了力地刺激和戳了这个东西，有人有想法吗？

你必须打电话new L.Marker()或L.marker()要修复您的第二个错误（在评论中），您必须首先定义您的 featureGroup，然后创建标记。var fg = new L.featureGroup();var WA0TJT = L.Marker(new L.LatLng(39.202911,-94.602887),{ contextmenu: true, contextmenuWidth: 140, contextmenuItems: [{ text: 'Click here to add mileage circles', callback: circleKoords}], icon: new L.NumberedDivIcon({number: '1' }), title:"marker_1" }).addTo(fg).bindPopup("1<br><b>ID: #0013</b><br>WA0TJT<br>Keith Kaiser<br>Platte Co., MO Dist: A<br>39.202911, -94.602887<br>EM29QE").openPopup();您也不会在地图上看到任何内容，因为您没有将要素组添加到地图中。你需要一个地图实例。var map = L.map('map', {...});fg.addTo(map);
