Jquery sorting html table rows by date

I have been using a script to sort tables by a date string which I got from stackoverflow but the code has stopped working. May I kindly ask if anybody knows why?

$('tr.Entries').each(function() {

  var $this = $(this),

    t = this.cells[1].textContent.split('-');

  $this.data('_ts', new Date(t[2], t[1] - 1, t[0]).getTime());

}).sort(function(a, b) {

  return $(a).data('_ts') > $(b).data('_ts');

}).appendTo('tbody');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<table class="table-bordered" border="1">

  <thead>

    <tr class="Headers">

      <th>Number</th>

      <th>Date start

      </th>

      <th>Date end</th>

    </tr>

  </thead>

  <tbody>

    <tr class="Entries" data-id="13">

      <td data-field-type="string">1234</td>

      <td data-field-type="date">01-04-2015</td>

      <td data-field-type="date">01-04-2015</td>

    </tr>

    <tr class="Entries" data-id="24">

      <td data-field-type="string">1352</td>

      <td data-field-type="date">04-10-2012</td>

      <td data-field-type="date">23-10-2015</td>

    </tr>

    <tr class="Entries" data-id="8">

      <td data-field-type="string">1124</td>

      <td data-field-type="date">13-05-2014</td>

      <td data-field-type="date">01-04-2015</td>

Your code works perfectly, check your fiddle, and tell us what are you getting exactly? How it isn't working?

The compareFunction passed to sort needs to return an integer, if < is used, it's returning a boolean. The documentation mentions:

If compareFunction(a, b) is less than 0, sort a to an index lower than b, i.e. a comes first.

If compareFunction(a, b) returns 0, leave a and b unchanged with respect to each other, but sorted with respect to all different elements.

If compareFunction(a, b) is greater than 0, sort b to an index lower than a, i.e. b comes first.

Source: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort

The change needed is replace $(a).data('_ts') < $(b).data('_ts') with $(a).data('_ts') - $(b).data('_ts') or $(b).data('_ts') - $(a).data('_ts') depending on the order you want.

What you stated about compareFunction callback is correct, but it's not the case here, It's working with < and > there's no need to use -, the code is already working, check this fiddle.

It's using this.cells[1] the second column, that has dates, just by looking at the year they don't seem sorted (2015, 2012, 2014, 2013, 2013) the same order as the original html code.

The compareFunction passed to sort needs to return an integer, if < is used, it's returning a boolean. The documentation mentions:

If compareFunction(a, b) is less than 0, sort a to an index lower than b, i.e. a comes first.

If compareFunction(a, b) returns 0, leave a and b unchanged with respect to each other, but sorted with respect to all different elements.

If compareFunction(a, b) is greater than 0, sort b to an index lower than a, i.e. b comes first.

Source: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort

The change needed is replace $(a).data('_ts') < $(b).data('_ts') with $(a).data('_ts') - $(b).data('_ts') or $(b).data('_ts') - $(a).data('_ts') depending on the order you want.

This is not the real problem, it's also working with > or <, check this updated fiddle.

I see the same result on that fiddle. If < is changed to - the rows will be sorted by the value on first column .

What you stated about compareFunction callback is correct, but it's not the case here, It's working with < and > there's no need to use -, the code is already working, check this fiddle.

It's using this.cells[1] the second column, that has dates, just by looking at the year they don't seem sorted (2015, 2012, 2014, 2013, 2013) the same order as the original html code.
