jquery cookie array loop

Question

I'm trying to read an array from a cookie like this:

var arr = $.makeArray($.cookie("mycookie"));

jQuery.each(arr, function() {
  $('#' + this).removeClass('collapsed');
});

The problem is it works only with the first item from the array. Can you help?

$.makeArray doesn't magically turn strings into arrays. It's for converting array-like objects into proper JavaScript arrays. Example:

> $.makeArray('a b c d')
  ["a b c d"]

...which is probably not what you're looking for.

Your question does not include what the value of $.cookie("mycookie") is, but assuming it's something like 'a b c d', you can just use String.split():

var arr = $.cookie("mycookie").split(' ');

jQuery.each(arr, function() {
  $('#' + this).removeClass('collapsed');
});

Thanks. Now I have a better understanding. The value of the cookie is 'a,b,c,d'

Okay, then just use .split(',') - it sounds like you already figured that out, though.
