jquery - Json data - Undefined -

i seek json result controller action.

in view have ajax.actionlink

@ajax.actionlink("aggiungi riga", "step2", new ajaxoptions { url = url.action("ritornarighejson"), onsuccess = "processdata" })

into controller have

public jsonresult ritornarighejson() { rigafattura info = new rigafattura(); data.descrizione = "json"; data.nriga = 1; homecoming json(data, jsonrequestbehavior.allowget); }

that produce json object . test action ritornarighejson , see right output.

now problem onsuccess = "processdata". view have javascript class

<script type="text/javascript"> function processdata(data) { alert(data) var = data[0]; alert(a); } </script>

but value of info "undefined"

i solved. problem controller. alter into

public jsonresult ritornarighejson() { rigafattura[] elenco = {new rigafattura{nriga = 1,descrizione="prova riga"}}; ienumerable<rigafattura> info = elenco; homecoming json(data, jsonrequestbehavior.allowget); }
