LeafletJS，无法将弹出窗口绑定到第二个标记

Question

我无法在使用 LeafletJS 时将弹出窗口绑定到第二个标记，第一个标记工作得很好，有什么帮助吗？这是我的 javascript 代码：

        var map = L.map('mapScene', {
                zoomControl: false,
        attributionControl: false,
    }).fitWorld();

    var playerIcon = L.icon({
        iconUrl: 'img/playermarker.png',
        shadowUrl: 'img/marker-shadow.png',

        iconSize: [25, 41],
        iconAnchor: [12, 41],
        popupAnchor: [1, -34],
        shadowSize: [41, 41]
    });

        var itemsIcon = L.icon({
        iconUrl: 'img/crate.png',
        shadowUrl: 'img/marker-shadow.png',

        iconSize:     [45, 46], // size of the icon
        shadowSize:   [50, 64], // size of the shadow
        iconAnchor:   [22, 94], // point of the icon which will correspond to marker's location
        shadowAnchor: [10, 117],  // the same for the shadow
            popupAnchor: [1, -34],
    });



    L.tileLayer('http://stamen-tiles-{s}.a.ssl.fastly.net/watercolor/{z}/{x}/{y}.{ext}', {
        minZoom: 14,
        maxZoom: 14,

        subdomains: 'abcd',
        ext: 'png'
    }).addTo(map);


   var playerMarker;

    function onLocationFound(e) {
        var radius = e.accuracy / 2;


       playerMarker = L.marker(e.latlng, {
            icon: playerIcon
        }).addTo(map).bindPopup("Hey i'm you!");

                addMarkers();
    }

        function addMarkers(){
            alert();

            L.marker(playerMarker + 2, {
                    icon: itemsIcon
            }).addTo(map).bindPopup("").on('popupopen', function() {
            alert();
            });
        }


    function onLocationError(e) {
        alert(e.message);
    }

    map.on('locationfound', onLocationFound);
    map.on('locationerror', onLocationError);

    map.locate({
        setView: true,
        maxZoom: 16
    });

通过函数 "addMarkers()" 添加的第二个标记显示完美无缺，但 .bindpopup 根本不起作用。您可以单击标记但没有显示任何内容，也没有显示警报。

感谢@ghybs fiddle。这里有一个working fiddle。我不知道您怎么会认为它可以与 playerMarker + 2 一起作为 latLng 使用，但看起来这是个错误。标记和整数之间的加法不起作用。

[编辑] 这是一段有趣的代码：

function onLocationFound(e) {
    var radius = e.accuracy / 2;
    playerMarker = L.marker(e.latlng).addTo(map).bindPopup("Hey i'm the first marker ");

    addMarkers();
}

function addMarkers() {
  //alert();
  var ll = playerMarker.getLatLng();
  var ll2 = L.latLng(ll.lat+12, ll.lng+12);
  var mm = L.marker(ll2).addTo(map);
  mm.bindPopup("Hey i'm the second marker");
}

LeafletJS，无法将弹出窗口绑定到第二个标记
