Array to Cookie

[Michael42]

Hello, I have an array of about 20 string elements, what is the best way to write and retreive them from a cookie?

Please, please give an example.

Also, is there a maximum file size for cookies?


Thanks very much,

Michael

Check this link for max cookie size:

Here are functions to work with cookies:

function setCookie(name,value,daysTillExpires)
  {
  var name_value = name + "=" + escape(value);
  if (!daysTillExpires) daysTillExpires = "";
  else
    {
    var D = new Date();
    var mill = D.getTime();
    D.setTime(mill + Math.round(daysTillExpires * 86400000));
    daysTillExpires = "; expires=" + D.toGMTString();
    }
  var full = name_value + daysTillExpires;
  document.cookie = full;
  }

function killCookie(name)
  {
  var D = new Date();
  D.setTime(10);
  var full = name + "=; expires=" + D.toGMTString() + "; path=/";
  document.cookie = full;
  }

function getCookie(name)
  {
  if (document.cookie) var C = document.cookie;
  else return "";
  var pair = "";
  var arr = C.split("; ");
  for (var i=0;i<arr.length;i++)
    {
    if (arr[i].indexOf(name + &quot;=&quot;) == 0) pair = arr[i];
    }
  if (pair == &quot;&quot;) return &quot;&quot;;
  var result = pair.substring(pair.indexOf(&quot;=&quot;) + 1, pair.length);
  return unescape(result);
  }

Now, if you have an array you'd like to store, use something like this:

setCookie("storedArray",myArray.join("+"));

The join() method puts the array into a single string separated by whatever is in the quotes.
