Ich kopierte diese Daten und testete mit einem Link http://geojsonlint.com/ , wo es die Geojson-Objekt-Layer erstellt. Aber wenn ich es in meiner Karte Skript bin mit als
geojson = L.geoJson(statesData, {
style: style,
onEachFeature: onEachFeature
}).addTo(map);
unter Angabe der mir ein Fehler als nicht erfasste Fehler: Ungültige GeoJSON Objekt.
Ich bekomme nicht den Grund des Fehlers. Muss ich meine String-Variablen StatesData zu Geojson analysieren. Wenn ja, wie kann ich String-Daten zu GEOJSON analysieren?
Bitte helfen Sie mir ...
Sieht aus wie Sie String zu JSON konvertieren müssen zuerst: statesData = JSON.parse (statesData) und dann Verwende die Variable wie üblich. – semanser
