Je ne cherche pas quelqu'un pour faire mon travail pour moi ... J'ai besoin d'aide/conseil.Comment utiliser un cookie pour détecter si l'utilisateur a déjà envoyé le formulaire?
J'ai besoin de:
Modifier la page de formulaire afin que lorsque la fonction JavaScript a vérifié que tous les champs obligatoires ont été remplies, un cookie est ajouté à l'ordinateur de l'utilisateur. Si le même utilisateur tente de remplir le formulaire une deuxième fois, l'utilisateur sera redirigé vers une page HTML distincte pour l'informer qu'il a déjà envoyé le formulaire.
Qu'est-ce que je fais mal?
C'est ma forme:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Request Form</title>

<script>
<!-- page to go to if cookie -->
go_to = "Submit.html";
num_days = -1;
function ged(noDays){
var today = new Date();
var expr = new Date(today.getTime() + noDays*24*60*60*1000);
return expr.toGMTString();
}
function readCookie(cookieName){
var start = document.cookie.indexOf(cookieName);
if (start == -1){
document.cookie = "seenit=yes; expires=" + ged(num_days);
} else {
window.location = go_to;
}
}
readCookie("seenit");
</script>
<script type="text/javascript" >
function verify() {
var themessage = "You are required to complete the following fields: ";
if (document.form.first.value=="") {
themessage = themessage + " - First Name";
}
if (document.form.middle.value=="") {
themessage = themessage + " - Middle Initial";
}
if (document.form.last.value=="") {
themessage = themessage + " - Last Name";
}
if (document.form.street.value=="") {
themessage = themessage + " - Street";
}

themessage = themessage + " - City";
}

themessage = themessage + " - State";
}
if (document.form.zip.value=="") {
themessage = themessage + " - Zip Code";
}
if (document.form.email.value=="") {
themessage = themessage + " - E-mail";
}
if (document.form.areacode.value=="") {
themessage = themessage + " - Area Code";
}
if (document.form.telephone.value=="") {
themessage = themessage + " - Telephone";
}
if (themessage == "You are required to complete the following fields: ") {

}

return false;
}
