I am trying to write a simple script in vain.
I need it to first check to see if the cookie exists
then if not
write one with two variable
[...]
I need this cookie to last just one day.
I compiled these functions some time ago, I hope it helps. (I've just translated the names from Spanish using Search & Replace, I hope I didn't break it)
/*
* Creates a cookie - name [value] [timeToExpire (s)] [path] [domain] [secure (bool)]
*/
function createCookie(name, value, timeToExpire, path, domain, secure){ // v2005-03-02
if(timeToExpire){
var expires=new Date();
expires.setUTCMilliseconds(expires.getUTCMilliseco nds()+1000*timeToExpire);
}
document.cookie=escape(name) + '=' + (value? escape(value) : '') +
(expires? '; expires=' + expires.toGMTString() : '') +
(path? '; path=' + escape(path) : '') +
(domain? '; domain=' + escape(domain) : '') +
(secure? '; secure' : '');
}
/*
* Removes a cookie
*/
function removeCookie(name){ // v2005-03-02
createCookie(name, '', -86400*365*10);
}
/*
* Returns the value of a cookie (null if it doesn't exist)
*/
function readCookie(name){ // v2005-02-27
eval('var re=/^('+escape(name)+')=(.*)$/i;');
var c=document.cookie.split(/;\s*/);
for(var i in c){
if(re.test(c[i])){
return unescape(re.exec(c[i])[2]);
}
}
return null;
}
