How can I save a cookie
Question
I'm trying to save a cookie and then load it again
I have this code
<html>
<head>
<script>
var myCookies = {};
function saveCookies()
{
myCookies["_uuser"] = document.getElementById("user").value;
myCookies["_uuage"] = document.getElementById("age").value;
//Start Reuseable Section
document.cookie = "";
var expiresAttrib = new Date(Date.now()+60*1000).toString();
var cookieString = "";
for (var key in myCookies)
{
cookieString = key+"="+myCookies[key]+";"+expiresAttrib+";";
document.cookie = cookieString;
}
//End Reuseable Section
document.getElementById("out").innerHTML = document.cookie;
}
function loadCookies()
{
//Start Reuseable Section
myCookies = {};
var kv = document.cookie.split(";");
for (var id in kv)
{
var cookie = kv[id].split("=");
myCookies[cookie[0].trim()] = cookie[1];
}
//End Reuseable Section
document.getElementById("user").value = myCookies["_uuser"];
document.getElementById("age").value = myCookies["_uuage"];
}
</script>
</head>
<body>
User: <input type="text" id="user">
Age: <input type="text" id="age">
<button onclick="saveCookies()">Save To Cookies</button>
<button onclick="loadCookies()">Load From Cookies</button>
<p id="out"></p>
</body>
</html>
when I type an input for both name and age, and click on save to cookies, and then clock on load from cookies, I got this "undefined" for both user and age!!
what's missing in my code, so I can save the cookie

For Chrome cookies can only be set, when the page is running on a webserver. For example accessed via http://localhost/foo/bar.html or http://127.0.0.1/foo/bar.html
edit : you might check out as well this answer: where cookie saved for local HTML file I just tested it myself: it works with Firefox.
Otherwise it would be better for testing such cases, to put up a local webserver like apache

I have tested your code from a web server and it works fine.
You must load it from a web server, rather from the local file system.
JSFiddle is here if you want to prove it for yourself.

Note that due to JSFiddle limitations I had to move the click triggers for the buttons to code like this:
document.getElementById("load").addEventListener("click", loadCookies);
document.getElementById("save").addEventListener("click", saveCookies);
...but that is irrelevant to my answer!
