How to handle cookies in JavaScript? [duplicate]

Answer 1

You're only setting a value for cookieminutes in the top section of the if statement, so any references in the else section will be null.

Try this:

function getcookie()
{
    var start = document.cookie.indexOf("expires");
    var cookiedate;

    cookiedate = new Date();
    cookieminutes = cookiedate.getMinutes();

    if(start==-1)
    {    
        document.write("Start equal to -1");
        document.cookie="expires="+cookiedate+",path=0,domain=0";    
    }
    else
    {
        document.write("Start not equal to -1");

        var date =  new Date();
        var minutes = date.getMinutes();

        document.write("The difference is "+minutes);
        document.write("
Cookie minutes is "+cookieminutes);
        return (minutes-cookieminutes);

    }
}
