初学cookie，有问题请教

如何实现动态存储cookie？动态readcookie？下面的代码思路可行吗？要如何修改呢？
<script language="javascript">
<!--
var i=1;
var j = 1;
function setCookie()
{
var the_name = "the_name" + j;
ck = prompt("What's your name?");
the_name = escape(ck);
document.cookie = the_name;
j = j + 1;
}
function check()
{document.all.tt.value = document.cookie;}
function readCookie()
{
var the_name = "the_name" + i;
the_name = document.cookie;
var broken_cookie = the_name.split(";");
var the_cookie = broken_cookie[0];
var the_cookie = unescape(the_cookie);
document.all.tt.value = the_cookie;
alert("Your name is: " + the_cookie);
i++;
}
-->
</script>
<INPUT style="Z-INDEX: 101; LEFT: 296px; POSITION: absolute; TOP: 224px" onclick="readCookie()" type="button" value="readck">
<INPUT style="Z-INDEX: 102; LEFT: 216px; POSITION: absolute; TOP: 224px" onclick="setCookie()" type="button" value="setck">
<INPUT id="tt" style="Z-INDEX: 103; LEFT: 216px; POSITION: absolute; TOP: 288px" type="text">
<INPUT style="Z-INDEX: 104; LEFT: 376px; POSITION: absolute; TOP: 224px" onclick="check()" type="button" value="check">

cookie格式：name=value; name=value; name=value....
用分号[;]做分割符，自己解析吧

也可以用不同的cookiename的吧？
