  • Save where? That’s the question!

  • To save the typed content in the textarea you must first place it in a form and submit the submission through an input type Submit, as a reading suggestion I recommend the following link: http://tableless.com.br/formulario-basic-in-8-minute/. About how to save is relative, you want to do save in a txt file, database...?

  • maybe he wants to use something like HTML5’s Storage site http://www.w3schools.com/html/html5_webstorage.asp

Using the Local Storage of HTML5 you can save textarea text locally, so even though you close the file the values will be there.

Code:

<!DOCTYPE html>
<html>
    <body>

    <html><table><textarea id='result'>Escreva aqui seu lembrete</textarea></table></html>
    <button onClick="salvar()">Salvar</button>

    <script>

    function salvar() {
        // Check browser support
        if (typeof(Storage) !== "undefined") {
            // Store
            localStorage.setItem("text", document.getElementById("result").value);

        } else {
            document.getElementById("result").innerHTML = "Local Storage não suportado";
        }
    }

    // Retrieve
        document.getElementById("result").innerHTML = localStorage.getItem("text");
    </script>

    </body>
</html>
