The examples in this article describe JavaScript settings and how to get cookies. Share to everyone for your reference, specific as follows:

1. Set Cookies

function Setcookie (Cookiename,cookievalue,cookieexpires,cookiepath)
{
  cookievalue = Escape (Cookievalue); /encoded latin-1
  if (cookieexpires== "")
  {
    var nowdate = new Date ();
    Nowdate.setmonth (Nowdate.getmonth () +6);
    Cookieexpires = Nowdate.togmtstring ();
  }
  if (cookiepath!= "")
  {
    cookiepath = "; Path= "+cookiepath;
  }
  document.cookie= cookiename+ "=" +cookievalue+ "; expires=" +cookieexpires+cookiepath;
}

2. Get cookies

function Getcookievalue (cookiename)
{
  var cookievalue = document.cookie;
  var cookiestartat = Cookievalue.indexof ("" +cookiename+ "=");
  if (cookiestartat==-1)
  {
    Cookiestartat = Cookievalue.indexof (cookiename+ "=");
  }
  if (cookiestartat==-1)
  {
    cookievalue = null;
  }
  else
  {
    Cookiestartat = cookievalue.indexof ("=", Cookiestartat) +1;
    Cookieendat = Cookievalue.indexof (";", Cookiestartat);
    if (cookieendat==-1)
    {
      cookieendat = cookievalue.length;
    }
    Cookievalue = unescape (cookievalue.substring (Cookiestartat,cookieendat));//decode Latin-1
  } return
  Cookievalue;
}

Example:

<!doctype html>

Attention:

Because Google Chrome browser for security only support Online-cookie, so in the local test is not effective, you need to upload to the server to try.
