Set/Get/Delete Cookies with jQuery


There are a lot of plugins you can use to set, get, and delete cookies using jQuery, but there’s also a fairly simple code that will achieve all three of those actions without the need for a heavy plugin. Check out the snippets below:

Set cookies:

function setCookie(name, value, expires, path, domain, secure) {
    var today = new Date();
    today.setTime(today.getTime());
    if (expires) {
        expires = expires * 1000 * 60 * 60 * 24;
    }
    var expires_date = new Date(today.getTime() + (expires));
    document.cookie = name + '=' + escape(value) +
        ((expires) ? ';expires=' + expires_date.toGMTString() : '') + //expires.toGMTString()
        ((path) ? ';path=' + path : '') +
        ((domain) ? ';domain=' + domain : '') +
        ((secure) ? ';secure' : '');
}

Get cookies:

 function getCookie(name) {
     var start = document.cookie.indexOf(name + "=");
     var len = start + name.length + 1;
     if ((!start) & amp; & amp;
         (name != document.cookie.substring(0, name.length))) {
         return null;
     }
     if (start == -1) return null;
     var end = document.cookie.indexOf(';', len);
     if (end == -1) end = document.cookie.length;
     return unescape(document.cookie.substring(len, end));
 }

Delete cookies:

function deleteCookie(name, path, domain) {
    if (getCookie(name)) document.cookie = name + '=' +
        ((path) ? ';path=' + path : '') +
        ((domain) ? ';domain=' + domain : '') +
        ';expires=Thu, 01-Jan-1970 00:00:01 GMT';
