Cerca nella pagina

[gachio]

Cambiamo allora...

Ho trovato questo ed è simile a quello che cercavo io anche se questo cerca una parola all'inerno di una pagina. Il problema è che la parola trovata viene evidenziata in basso nella pagina e non in alto com io vorrei
potreste aiutarmi almeno con questo codice?

Ho trovato questo, ma la parola in questione viene evidenziata e posta al di sotto della pagina e non in alto a sx
potreste aiutarmi con questo codice almeno?

E` un problema completamente diverso. Va messo in una discussione diversa.

Quando si posta un codice complesso, e` bene racchiuderlo tra tag [ code ] ... [ /code ] (senza gli spazi), in modo che vengano preservate la formattazione e l'indentazione.
