          var defineclass = '';              $('.crad').each(function( index){                 defineclass = localstorage.getitem('class' + index);                 $(this).addclass(defineclass)                            });                             $('.crad').click(taskfunction);         function taskfunction(){               if ( $( ).hasclass( "fa-circle" ) ) {                    $( ).removeclass('fa-circle').addclass('fa-circle-o');                     localstorage.setitem('class' + $(this).index(), 'fa-circle-o');               }else{                    $(this).removeclass('fa-circle-o').addclass('fa-circle');                    localstorage.setitem('class'+$(this).index(), 'fa-circle');                  }              }

store class info based on index wise.
