Check for cookie on page load and redirect to another page if found

[redrose43311]

I am trying to add a code to my contact page that checks for a cookie named NewCookie, and if this cookie is found it will redirect the user to another page called alreadysubmitted. I have tried everything I can,.

I have tried the onload command and tried to break down ones like this but I am very new to javascript and I believe with all the site and things I have tried I have made myself very confused.

function getCookie(NewCookie)
{ if (document.cookie.length > 0)
{ begin = document.cookie.indexOf(NewCookie+"=");
if (begin != -1)
{ begin += NewCookie.length+1;
end = document.cookie.indexOf(";", begin);
if (end == -1) end = document.cookie.length;
return unescape(document.cookie.substring(begin, end)); }
}
return null;
}
 
 
 
function setCookie(NewCookie, Website cookie value, expiredays)
{ var ExpireDate = new Date ();
ExpireDate.setTime(ExpireDate.getTime() + (expiredays * 24 * 3600 * 1000));
document.cookie = NewCookie + "=" + escape(value) +
((expiredays == null) ? "" : "; expires=" + ExpireDate.toGMTString());
}
 
 
 
function delCookie (NewCookie)
{ if (getCookie(NewCookie)) {
document.cookie = NewCookie + "=" +
"; expires=Thu, 30 Dec 2013 00:00:01 GMT";
}
 
}
