Question

我有名为json_point2的GeoJSON文件。该文件保存点数据如下。

var json_point2={
"type": "FeatureCollection",
"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" } },
"features": [
{ "type": "Feature", "properties": { "Class": null }, "geometry": { "type": "Point", "coordinates": [ 40.193168611061743, 40.904508523555492 ] } },
{ "type": "Feature", "properties": { "Class": null }, "geometry": { "type": "Point", "coordinates": [ 40.191358449981372, 40.902051540140285 ] } },

当我在我的网络应用上点击此点时，我想输入类的输入值并再次保存该值。

我可以使用以下代码单击该点并输入该属性。但是他并没有将它记录在他的数据库中。

mycode的

 map.createPane('pane_point2');
map.getPane('pane_point2').style.zIndex = 602;
map.getPane('pane_point2').style['mix-blend-mode'] = 'normal';
var layer_point2 = new L.geoJson(json_point2, {
    attribution: '<a href=""></a>',
    pane: 'pane_point2',
    onEachFeature: function (feature, layer) {
        var input = L.DomUtil.create('input', 'my-input');
        input.value = feature.properties.Class;
        L.DomEvent.addListener(input, 'change', function () {
            feature.properties.Class = input.value;
        });
        layer.bindPopup(input);
        layer_point2.toGeoJSON();
    }   
}).addTo(map);

如何使用传单添加和保存要素属性GeoJSON
