Question

我在mapbox中有一条自定义行，当您单击它时会显示一个弹出窗口，我该如何做使其仅在您将鼠标悬停时才显示？我从“单击”更改为“ mouseenter”，但没有关闭弹出窗口。什么需要改变？

您的代码是正确的，但是其中有一个小错误，您为Source和Layer选择了相同的ID ...只需在map.addLayer和click事件中以不同的方式调用它即可，{{3 }}

    mapboxgl.accessToken = 'pk.eyJ1IjoibWFya2V0aW5nYnNvIiwiYSI6ImNrYnYwZmk3YjAxZjgyem1wY2Zmc3F4Y2EifQ.gMF-eCCaAHHgWIUoRcnfkg';
    var map = new mapboxgl.Map({
        container: 'map',
        style: 'mapbox://styles/mapbox/streets-v11',
        center: [-0.066985, 51.503363],
        zoom: 9
    });

    map.on('load', function () {
        var popup;
        map.addSource('routeThree', {
            'type': 'geojson',
            'data': {
                'type': 'Feature',
                'properties': {},
                'geometry': {
                    'type': 'LineString',
                    'coordinates': [
                        [-0.066985, 51.503363],
                        [-3.550610, 40.390555],
                        [-77.140217, 38.801481],
                        [-118.175979, 34.008447]
                    ]
                }
            }
        });
        map.addLayer({
            'id': 'routeThree2',
            'type': 'line',
            'source': 'routeThree',
            'layout': {
                'line-join': 'round',
                'line-cap': 'round'
            },
            'paint': {
                'line-color': '#04A5BD',
                'line-width': 8
            }
        });
        map.on('mouseover', 'routeThree2', function (e) {
            popup = new mapboxgl.Popup()
                .setLngLat(e.lngLat)
                .setHTML("<h2>This is the third line that will explain something</h2>")
                .addTo(map);

        });

        map.on('mouseout', 'routeThree2', function (e) {
            if (popup) popup.remove();

        });


    });
