I can hear it already. "There are already a thousand scripts for getting and setting cookies! Why do we need another one?" That's a good question.

Most of the cookie scripts out there have serious flaws regarding how they search for cookie names. If you're trying to get the value for a cookie named "ant" and there's another cookie named "plant" you could get either value back depending on the order they appear in document.cookie.

ScriptingMagic presents sm-cookie.js. It provides the standard getCookie, setCookie, and deleteCookie functions. It also creates and maintains a window property named cookies which is an associative array for even faster read access.

Example

var bat = cookies['bat'];
var at = cookies['at'];
var t = cookies['t'];

document.write('Initial bat value: ' + bat + '<br />');
document.write('Initial at value: ' + at + '<br />');
document.write('Initial t value: ' + t + '<br /><br />');

if (!bat)
{
	bat = 1;
	at = 100;
	t = 'A';
}
else
{
	bat++;
	at--;
	t += String.fromCharCode(bat + 0x40);
}

setCookie('bat', bat);
setCookie('at', at);
setCookie('t', t);

document.write('New bat value: ' + cookies['bat'] + '<br />');
document.write('New at value: ' + cookies['at'] + '<br />');
document.write('New t value: ' + cookies['t'] + '<br />');

</script>
