Question

我在页面加载时加载了一个标记，我希望在用户单击地图时删除该标记并添加另一个标记，但是它不起作用。

这就是我尝试过的

 var map = L.map('map').setView([35.79, 51.47], 13);
    L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
        attribution: '&copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors'
    }).addTo(map);


    theMarker = { lat: 35.810992207495154, lng: 51.45223617553712};
    L.marker(theMarker, {
        draggable: true,
        title: "Resource location",
        alt: "Resource Location",
        riseOnHover: true
    }).addTo(map)
    map.on('click', function (e) {
        lat = e.latlng.lat;
        lon = e.latlng.lng;

        alert("You clicked the map at LAT: " + lat + " and LONG: " + lon);
        //Clear existing marker, 

        if (theMarker != undefined) {
            map.removeLayer(theMarker);
        };

        //Add a marker to show where you clicked.
        theMarker = L.marker([lat, lon]).addTo(map);
    });

这是一个工作示例 https://jsfiddle.net/ky0xrpe9/

    theMarkerLatLng = { lat: 35.810992207495154, lng: 51.45223617553712};
    theMarker = L.marker(theMarkerLatLng, {
        draggable: true,
        title: "Resource location",
        alt: "Resource Location",
        riseOnHover: true
    }).addTo(map)
