Alternativ könnte man es auch so schreiben …
nützt das was ???
oder evtl. der link zu der Seite, wobei ich mir hier die Infos via. Chrome mit dem “Entwicklertool” ansehe
data: [,…]
0: {id: "59260", name: "MaLIS1_Käfertaler_Straße", status: "active", address: "Käfertaler Straße 15",…}
evses: [{uid: "131880", id: "DE*MVV*E00066*R1", status: "AVAILABLE", reservable: false,…},…]
0: {uid: "131880", id: "DE*MVV*E00066*R1", status: "AVAILABLE", reservable: false,…}
Habe den json Code auch gefunden:
Bei meiner Abfrage bekomme ich NUR bei
“Schafweide L1” den korrekten Wert zurück …
Für die Abfragen von " selectattr(‘uid’ … )
bekomme ich gar nichts od bei R3 “unbekannt” zurück …
Hilfe?!
