Voici le code html que je voudrais transformer:

//<![CDATA[
window.onload = function () {
    document.getElementById('email-form').submit();
}
//]]>
</script>
<form method="post" id="email-form" action=".../generateurdepseudo.php?action=generate">
<textarea class="bbcode-textarea-textarea" name="about" id="bbcode-textarea">PSEUDO
</textarea>
<input type="hidden" name="action" value="about" />

</form>
