我正在使用 Leaflet 和 OpenStreetMap 在我的页面上显示地图。我按照步骤在页面上创建了一个简单地图。一旦我能够生成地图，我就会按照创建 geojson 文件的步骤，转到 https://geojson.io/。
我遇到的问题是当我调用文件时，出现以下错误：“未捕获错误：无效的 GeoJSON 对象。”。不知道我做错了什么。
以下是代码：

const myGeoJSONData = 'json/geomap.geojson';
const mymap = L.map('map').setView([34.0000, -118.300], 13);
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {

}).addTo(mymap);
const laCounty = L.marker([34.05951960593492, -118.25037820245461], 13).addTo(mymap);
laCounty.bindPopup("<b>Location Name</b><br><b>Address:</b> <br /><b>Phone:</b>").openPopup();
mymap.on('click', function(e) {
L.marker(e.latlng).addTo(mymap);
});
var myGeoJSONLayer = L.geoJSON(myGeoJSONData, {
style: function(feature) {
return {color: feature.properties.color};
},
onEachFeature: function(feature, layer) {
layer.bindPopup(feature.properties.name);
}
}).addTo(mymap);
</script>
</body>
</html>
以下是geojson：
{
"type":"FeatureCollection",
"features":[
{
"type":"Feature",
"geometry":{
"type":"Point",
"coordinates":[
34.05951960593492,
-118.25037820245461
]
},
"properties":{
"name":"location name",
"address":"address of location",
"phone_number":"phone number"
}
}
]
}
myGeoJSONData在脚本中内联 geojson 数据。
const myGeoJSONData = {
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [
34.05951960593492,
-118.25037820245461
]
},
"properties": {
"name": "location name",
"address": "address of location",
"phone_number": "phone number"
}
}
]
}
var myGeoJSONLayer = L.geoJSON(myGeoJSONData, {
style: function (feature) {
return { color: feature.properties.color };
},
onEachFeature: function (feature, layer) {
layer.bindPopup(feature.properties.name);
}
}).addTo(mymap);
