同位素按特定名称和日期排序

Question

我有一些带有排序按钮的简单isotope列表：

// init Isotope
var $grid = $('.grid').isotope({
  itemSelector: '.element-item',
  layoutMode: 'fitRows',
  getSortData: {
    date: function ( itemElem  ) {
              return Date.parse($( itemElem ).find('.date').data('time'));
          },
          popular: function ( itemElem  ) {
              return parseInt($( itemElem ).find('.comment').data('comment'), 10);
          },
          name1: function ( itemElem  ) {
              return $( itemElem ).find('.name1');
          },
          name2: function ( itemElem  ) {
              return $( itemElem ).find('.name2');
          },
          name3: function ( itemElem  ) {
              return $( itemElem ).find('.name3');
          },
  },
  sortAscending: false,
  // sortBy: 'new',
});

// bind sort button click
$('.sort-by-button-group').on( 'click', 'button', function() {
  var sortValue = $(this).attr('data-sort-value');
  $grid.isotope({ sortBy: sortValue });
});

// change is-checked class on buttons
$('.button-group').each( function( i, buttonGroup ) {
  var $buttonGroup = $( buttonGroup );
  $buttonGroup.on( 'click', 'button', function() {
    $buttonGroup.find('.is-checked').removeClass('is-checked');
    $( this ).addClass('is-checked');
  });
});

.element-item {
  border:1px solid #eee;
  width: 100%;
  padding-left: 1rem;
  font-family: monospace;
}

.date {
  display: block;
  color:#777;
  margin-bottom: 1rem;
}

.comment {
  display: block;
  margin-bottom: 1rem;
}

button.is-checked {
  background: #000;
  color: #fff;
}

问题：如何按特定名称对列表进行排序，例如，首先是所有Name 1，然后是所有其他名称？

问题：如何按日期格式DD-MM-YYTHH:MM:SS（例如01-01-2018T08:23:11）对列表进行排序？

不过滤，仅排序，仅同位素！

附言：：现在所有项仅对热门帖子进行排序。对其余部分进行某种排序会奇怪地起作用（不是应该的）。
