拾取图元要素

使用示例

<script>
    var map = L.map('map', {
        crs: L.CRS.CustomEPSG4326,
        center: {lon: 120.09215287988154, lat: 30.277052933991797},
        zoom: 12,
        inertiaDeceleration: 15000,
        maxZoom: 20
    })
    //添加底图
    var layer = new L.GXYZ(window.leaflet.vmapUrl + '&x={x}&y={y}&l={z}', {tileSize: 512})
    map.addLayer(layer)

    map.on('click', function (e) {
        var event = e.originalEvent
        //拾取要素
        var features = layer.getFeatureByXY(event.x, event.y, function (layerFeatures) {
            var ids = 'featureIDs : '
            for (var layername in layerFeatures) {
                ids = ids + layername + ': '
                for (var key in layerFeatures[layername]) {
                    ids = ids + key + ' '
                }
            }
            //打印拾取到的图层名和图层内的要素id
            alert(ids)
        })
    })
</script>
