Inserimento key in una function strurl

[ciopin183]

Salve ragazzi,

ho trovato un sito UK dove registrandoti ( e pagando) ti danno una user e una key da adoperare e anche gli script da adoperare per l'autocompletamento dati del tuo form se ti serve il postcode in UK. Esempio tu hai il cmapo postcode, l'0utente mette il suo post code e lui in automatico ti popola i campi address2, address2, city, county...una figata insomma. La function è questa ma ( da ignorante come una capra) mi chiedevo dove devo inserire la Key e l'User ( vedo che viene richiesta ma sintatticmante nn saprei come scriverlo) Mi aiutate per favore?

Grazie

      var scriptTag = document.getElementById("PCA38d38252878f434581f85b249661cd94");
      var headTag = document.getElementsByTagName("head").item(0);
      var strUrl = "";

      //Build the url
      strUrl = "http://services.postcodeanywhere.co.uk/PostcodeAnywhere/Interactive/RetrieveByPostcodeAndBuilding/v1.10/json.ws?";
