localStorage, saving a class using toggleClass

Question

I am clueless when it comes to localStorage it seems. I want to set up a way favorite any div in a group of div\'s by toggling a class. I can get the toggleClass to work on

Answer 1

In case the other answers questions do not suffice here is a solution that allows you to have multiple divs that will maintain state after reload rather than just one.

if (typeof(localStorage) == 'undefined') {
  document.getElementById("result").innerHTML =
    'Your browser does not support HTML5 localStorage. Try upgrading.';
} else {
    $(".item").each(function(i, el) {
      if (localStorage['fav' + i] == 'favorites') {
        $(this).addClass('favorites');
      }
    });
}
$(document).ready(function() {
  $('.btn').on('click', function() {
    var $item = $(this).closest('.item');
    var index = $('.item').index($item);
    $item.toggleClass('favorites');
    if ($item.hasClass('favorites')) {
      localStorage.setItem('fav' + index, 'favorites');
    } else {
      localStorage.removeItem('fav' + index);
    }
  });
});
