tengo el siguiente codigo
Código PHP:
<script language="JavaScript">
function CheckForm () {
var errorMsg = "";
//Check for a subject
if (document.frmAddMessage.subject.value==""){
errorMsg += "\n\tSubject \t\t- Enter a Subject for your new Topic";
}
//Check for message
if (document.frmAddMessage.message.value==""){
errorMsg += "\n\tMessage \t\t- Enter a Message to post";
}
//If there is aproblem with the form then display an error
if (errorMsg != ""){
msg = "_______________________________________________________________\n\n";
msg += "The form has not been submitted because there are problem(s) with the form.\n";
msg += "Please correct the problem(s) and re-submit the form.\n";
msg += "_______________________________________________________________\n\n";
msg += "The following field(s) need to be corrected: -\n";
errorMsg += alert(msg + errorMsg + "\n\n");
return false;
}
//Reset the submition page back to it's original place
document.frmAddMessage.action = "post_message.asp"
document.frmAddMessage.target = "_self";
frmAddMessage.Submit.disabled=true;
return true;
}
</script>
Código HTML:
<form method="post" name="frmAddMessage" action="post_message.asp=" onSubmit="return CheckForm();" onReset="return ResetForm();">
ASUNTO<INPUT TYPE="text" NAME="subject" size="70">
<IFRAME src="editor.asp?" width="100%" height="390" frameborder="no" scrolling="no" id="message"></IFRAME>
<input type="hidden" name="message" value="">
<input type="submit" name="Submit" value="Post New Topic" OnClick="document.frmAddMessage.message.value = frames.message.document.contenido.value;" tabindex="30" />
</form>
lo que necesito es que al enviar el formulario se verifique si ha ingresado el asunto y el contenido del tema. este codigo lo saque de otro lado pero solo me valida el campo subject. si alguien conoce la forma de saber el contenido del iframe y validarlo se lo agredecere.
