Salve ragazzi,  
è possibile effettuare la sostituzione automatica, in un testo inserito  
in textarea, degli “a capo” , da tastiera, con il tag html   
.

Grazie sempre per l’aiuto!

Luigi

Se usi rails c’è un helper apposito.

Si grazie, ho usato:

@item.text=@item.text.gsub(/\n/,"  
")

Grazie mille.

…pensavo andasse bene, ma ho un problema perché non fa la sostituzione  
ma, stranamente, lo aggiunge all’ “a capo”.

Quindi quando vado a fare una qualsiasi modifica mi rifà la sostituzione  
di /n con   
 aggiungendo quindi un altro   
.

Come mai?

Grazie

Luigi
