Multiple Dimensional Arrays in Cookies

Hi Stephen,

I am using your cookie toolbox and it is very handy so thank you very much!

Now I understand that it has no multidimensional array support, but I have worked out a way to do it. My method is as follows:

here I set the array, notice that ** delimeters

//set config cookie
  jc_params = document.forms['jc_config'].elements;

   jc_params_array = init_array();
  jc_params_array.splice(0,1);

  for(i=0; i    jc_params_array[i+1] = jc_params[i].id+'**'+jc_params[i].value;
  }

  var cookieName = 'jc_temp';
  var timeToKeep = 60000; // one minute
  var expires = new Date();
  expires.setTime(expires.getTime() + timeToKeep);

  set_array(cookieName, jc_params_array, expires);

When I access the cookie array I can simply use split() to get it back again.

function jc_initparams(){
  var cookieName = 'jc_temp';
  var jc_params_array = init_array();
  get_array(cookieName, jc_params_array);

  for (var i=1; i    results = jc_params_array[i].split('**');

  var param = results[0];
  var setting = results[1];

  jc_setparam(param, setting);
  }
}

This is handy if you need associative array support.

Hope this can help someone :)
