关于cookie的问题

[wangxj0600]

各位，请问怎么访问一个cookie，最好有关于cookie 的资料。

[dylanOK]

function createCookie(name,value,days)
{
try {
if (days)
{
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
} catch(e) {
alert('IE出错[ '+e.toString()+' ]，请重新提交！');
}
}
//
function readCookie(name)
{
try {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++)
{
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
} catch(e) {
alert('IE出错[ '+e.toString()+' ]，请重新提交！');
}
}

function eraseCookie(name)
{
try {
createCookie(name,"",-1);
} catch(e) {
alert('IE出错[ '+e.toString()+' ]，请重新提交！');
}
}

能不能同时打开多个cookie，分别对他们进行操作？
