javascript getting setting deleteing cookies

I am having trouble setting and deleting cookies in php Ive got no problem.. in javascript eh.. lots I know this question is everywhere but all the answers I come across seem to bring me the same fate so I have no idea whats going on.. this is what I have currently.

SetCookie("username",ztsUser,14,'/', '');

function SetCookie (name,value,expires,path,domain,secure) {
  document.cookie = name + "=" + escape (value) +
    ((expires) ? "; expires=" + expires.toGMTString() : "") +
    (开发者_运维技巧(path) ? "; path=" + path : "") +
    ((domain) ? "; domain=" + domain : "") +
    ((secure) ? "; secure" : "");
  }

the error:

expires.toGMTString is not a function

The whole lot of cookie functions I have.. is:

    var today = new Date();
var expiry = new Date(today.getTime() + 365 * 24 * 60 * 60 * 1000);

function getCookieVal (offset) {
  var endstr = document.cookie.indexOf (";", offset);
  if (endstr == -1) { endstr = document.cookie.length; }
  return unescape(document.cookie.substring(offset, endstr));
  }

function GetCookie (name) {
  var arg = name + "=";
  var alen = arg.length;
  var clen = document.cookie.length;
  var i = 0;
  while (i < clen) {
    var j = i + alen;
    if (document.cookie.substring(i, j) == arg) {
      return getCookieVal (j);
      }
    i = document.cookie.indexOf(" ", i) + 1;
    if (i == 0) break; 
    }
  return null;
  }

function DeleteCookie (name,path,domain) {
  if (GetCookie(name)) {
    document.cookie = name + "=" +
    ((path) ? "; path=" + path : "") +
    ((domain) ? "; domain=" + domain : "") +
    "; expires=Thu, 01-Jan-70 00:00:01 GMT";
    }
  }

function SetCookie (name,value,expires,path,domain,secure) {
  document.cookie = name + "=" + escape (value) +
    ((expires) ? "; expires=" + expires.toGMTString() : "") +
    ((path) ? "; path=" + path : "") +
    ((domain) ? "; domain=" + domain : "") +
    ((secure) ? "; secure" : "");
  }

if anyone knows a better method Im all ears.. but this is what I got at the moment, I need to set, update, delete, get the value of.. cookies

toGMTString has been deprecated. Try toUTCString instead:

function SetCookie (name,value,expires,path,domain,secure) {
  document.cookie = name + "=" + escape (value) +
    ((expires) ? "; expires=" + expires.toUTCString() : "") +
    ((path) ? "; path=" + path : "") +
    ((domain) ? "; domain=" + domain : "") +
    ((secure) ? "; secure" : "");
}

You're also passing a number (14) when the function expects a Date (expires.toUTCString):

SetCookie("username", ztsUser, 14, '/', '');

What is 14 intended to be? 14 days? Assuming that, you can add this at the top of the function to support both numbers and dates:

if ('number' === typeof expires) {
    expires = new Date(new Date().getTime() + expires * 86400000);
}

86400000 is the number of milliseconds in a day -- 24 * 60 * 60 * 1000.

There are already a number of great libraries for handling cookies in JS. Why not use one of them? Just go to your favorite search engine and enter "javascript cookie library" to find one.
