Create array in cookie with javascript

Question

Is it possible to create a cookie using arrays?

I would like to store a[0]=\'peter\', a[\'1\']=\'esther\', a[\'2\']=\'john\' i

Answer 1

For that example you can do it quite easily:

• Make Cookies:

  ///W3Schools Cookie Code:
  function setCookie(cname,cvalue,exdays) {
      var d = new Date();
      d.setTime(d.getTime() + (exdays*24*60*60*1000));
      var expires = "expires=" + d.toGMTString();
      document.cookie = cname + "=" + cvalue + ";" + expires + ";";
  }
  
  function getCookie(cname) {
      var name = cname + "=";
      var ca = document.cookie.split(';');
      for(var i = 0; i < ca.length; i++) {
          var c = ca[i];
          while (c.charAt(0) == ' ') {
              c = c.substring(1);
          }
          if (c.indexOf(name) == 0) {
              return c.substring(name.length, c.length);
          }
      }
      return "";
  }
  
  ///My Own Code:
  for(a=0;a

• Retrieve Array:

  for(a=0;a

For any array with other value types besides strings:

• Make Cookies:

  ///Replace MyCode above With:
  if(typeof b[a] === 'string'){
      setCookie(b[a],b[a],periodoftime);
  }else{
      setCookie(b[a].toString,b[a],periodoftime);
  }
  

• Retrieve Array:

  for(a=0;a

The only flaw is that identical values cannot be retrieved.

No JQuery needed, comma seperation or JSON.
