Need help making cookies
There are a lot of extremely smart members here, so I thought if the knowledge is out there, this would be the place to tap into it. I have included the code below that I am working with. What I want is for a person to enter their name and room number and coffee preference. Then a cookie will store that information and tell them a cup will be sent to them at their room. When the page is loaded again their preference will be remembered and they will be offered a discount for their favorite coffee. This is part of a self taught book I am studying.
Most of it works, but I think the selection of coffee from the radio button is not being stored in the cookie, or at least I can not recall it. I was also wondering if there was some way that I could combine the makeCookie and welcome functions so that there would only be one button to click on the page. Any ideas??? Code:
<html>
<head>
<title>Making a Cookie</title>
<script language="JavaScript">
function makeCookie(form){
var when = new Date();
when.setTime(when.getTime() + 24 * 60 * 60 * 1000);
// 24 hours from now
when.setFullYear(when.getFullYear() + 1);
// One year from now
yname=document.form1.yourname.value;
ycup=document.form1.coffee.value;
yroom=document.form1.yourroom.value;
document.cookie=escape("name")+"="+escape(yname, ycup, yroom)+
";expires="+when.toGMTString();
alert(document.cookie);
}
function welcome(){
you=document.form1.yourname.value;
room=document.form1.yourroom.value;
cup=document.form1.coffee.value;
var position=document.cookie.indexOf("name=");
if ( position != -1){
var begin = position + 5;
var end=document.cookie.indexOf(";", begin);
if(end == -1){ end=document.cookie.length;}
you= unescape(document.cookie.substring(begin, end));
alert("Welcome " + you + ",\n\nwe will be sending a fresh cup of " + cup + "\n\nto you in room number " + room );
}
else{ alert("No cookies today");}
}
function seeDiscount(){
you=document.form1.yourname.value;
room=document.form1.yourroom.value;
cup=document.form1.coffee.value;
var position=document.cookie.indexOf("name=");
if(document.cookie == ""){
alert("No cookies totay");
return false;
}
else {
if ( position != -1){
var begin = position + 5;
var end=document.cookie.indexOf(";", begin);
if(end == -1){ end=document.cookie.length;}
you= unescape(document.cookie.substring(begin, end));
alert("Welcome back " + you + ",\n\nGet a fresh cup of " + cup + " at 25% off today." );
}
else{ alert("No cookies today");}
}}
</script>
</head>
<body onLoad="seeDiscount()">
<h2>Room Service</h2>
<form name="form1">
What is your name? <br>
<input type="text" name="yourname" size="30">
<p>What is your room number? <br>
<input type="text" name="yourroom" size="3"> </p>
<p>What kind of coffee would you like?</p>
<p><input type="radio" name="coffee" value="Espresso">Espresso<br>
<input type="radio" name="coffee" value="Cappucino">Cappucino<br>
<input type="radio" name="coffee" value="Mocha">Mocha<br>
</p>
<p>
<input type="button" value="Make cookie" onclick="makeCookie();">
</p>
<p><input type="button" value="Welcome (Get cookie)" onclick="welcome();">
</p>
<p></p>
</form>
</body>
