									</tr>
								</table>

Un normalissimo form, vorrei dare il focus al primo campo in questo caso #rag_soc allora faccio così

$("#rag_soc").focus();

Ma stranissimamente non va, sapete qualcosa a riguardo?

[longilineo]

se nella stessa porzione di codice in cui fai

$("#rag_soc").focus();


fai qualcos'altro con lo stesso selettore funziona?

Ad es

alert($("#rag_soc").size());

Dovrebbe restituire 1
