geoJSON bindPopup示例

// 创建地图对象
var map = L.map('map').setView([51.505, -0.09], 13);

// 添加地图图层
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
    attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/">OpenStreetMap</a> contributors',
    maxZoom: 18,
}).addTo(map);

// 定义geoJSON数据
var geojsonFeature = {
    "type": "Feature",
    "properties": {
        "name": "Coors Field",
        "popupContent": "This is Coors Field."
    },
    "geometry": {
        "type": "Point",
        "coordinates": [-104.99404, 39.75621]
    }
};

// 创建geoJSON图层并添加到地图上
L.geoJSON(geojsonFeature, {
    onEachFeature: function (feature, layer) {
        // 绑定弹出窗口
        if (feature.properties && feature.properties.popupContent) {
            layer.bindPopup(feature.properties.popupContent);
        }
    }
}).addTo(map);
