Andrew Pallant's Weekly Code Snippet

Manage Cookies using JavaScript

This week's code sample is JavaScript based. I found this while researching JavaScript cookie routines. I personally cannot take credit for creating this routine, but I thought it would be good to share this example with other developers.

Important Note: Works with IE and FireFox

Input your name and press the button to see the results of the cookie.
Name:
function getexpirydate( nodays)
{
     var UTCstring;
     Today = new Date();
     nomilli=Date.parse(Today);
     Today.setTime(nomilli+nodays*24*60*60*1000);
     UTCstring = Today.toUTCString();
     return UTCstring;
}

function getcookie(cookiename)
{
     var cookiestring=""+document.cookie;
     var index1=cookiestring.indexOf(cookiename);
     if (index1==-1 || cookiename=="") return "";

     var index2=cookiestring.indexOf(';',index1);
     if (index2==-1) index2=cookiestring.length;

     return unescape(cookiestring.substring(index1+cookiename.length+1,index2));
}

function setcookie(name,value,duration)
{
    cookiestring=name+"="+escape(value)+";
     EXPIRES="+getexpirydate(duration);
     document.cookie=cookiestring;
     window.location.reload();
}
