    Problema con javascript

    Salve a tutti, avrei un problema da risolvere.Ho un file html con codice javascript all'interno(è editor html wysiwyg che si utilizza come una normale pagina web).Ebbene, mi funziona tutto, ma non so come risolvere un problema: in poche parole, ogniqualvolta che io cerco di visualizzare il codice html che è stato creato con l'editor visuale(infatti ho creato un link con questa funzione), questo mi compare in un messaggio alert.
    Infatti ho utilizzato questa seguente riga di codice:

    <a href="#" onClick="display();returne(false)">Visualizza il codice</a>

    Vorrei che, ogniqualvolta io clicchi sul link, mi apparisse il codice appena generato sotto il link, e non in un alert(infatti non permette di fare copia e incolla)
    Come fare?

Come fare?

La parte di codice che hai riportato è solo quella che richiama la funzione javascript.

Ma la funzione vera e propria function display()  che compie le operazioni si trova altrove.

Quindi è impossibile aiutarti solo alla luce di questo codice.

Puoi postare un link (non attivo) alla pagina in oggetto?

    Intanto c'è un errore sull'onclick , precisamente a "returne(false);".
    Magari lo hai scritto solo qui sul forum comunque controlla ugualmente 🙂
