sortable - a tiny, vanilla JS table sorter

Makes any table with class="sortable", er, sortable. That is the user can click on a table header and change the sorting of the table rows.

Just include the JavaScript and it will work. No function calls needed, all is done with an eventListener. (the CSS is not strictly needed, but makes it ~pretty and user friendly)

Please note that the advanced and mega-advanced version have been deprecated. I just couldn't justify their existense 🤷‍♂️ If you need advanced sorting, prepare the tables with the data-sort attribute instead. The same goes for the ES6 version, it seemed a bit pointless.

Factoids

713 bytes minified.
Works with JS/ajax generated tables.(due to the eventListener)
Lightning fast. Huge tables will make it slow and may freeze the browser, especially for mobiles, so you know...
Requires thead and tbody.
cross browser, ie9+
~~eventListeners attached to the rows WILL be removed~~
eventListeners are no longer removed! 😊
NOT tested with react, Angular, Vue, etc. There's just no way it will work without messing them up. Literally no way.

Demo

An example

<table class="sortable">
  <thead>
    <tr>
      <th>Role</th>
      <th>Name</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Genius</td>
      <td>Rick</td>
    </tr>
    <tr>
      <td><a href="javascript:alert('Inline javascript works!');">Sidekick</a></td>
      <td>Morty</td>
    </tr>
  </tbody>
</table>
<link href="sortable.css" rel="stylesheet" />
<script src="sortable.js"></script>

Non-sortable field

using `class=".no-sort"`

If you wish to disable sorting for a specific field, the easiest way is to add a class to it, like so:

<tr>
  <th class="no-sort">Role</th>
  <th>Name</th>
</tr>

and then use css to block clicks. like so:

th.no-sort {
  pointer-events: none;
}

using css only

This is a bit trickier, but it doesn't require any changes to the html, so I guess it could be worth it in some cases.

/* the first column in every sortable table
 should not be sortable*/
.sortable th:nth-child(1) {
  background: pink;
  color: red;
  pointer-events: none;
}

/* the seventh column in the second .sortable
 table should not be sortable*/
.sortable:nth-of-type(2) th:nth-child(7) {
  background: pink;
  color: red;
  pointer-events: none;
}

The `data-sort` attribute

Using the data-sort attribute you can have one visible value and one sortable value. This is useful in case you have for instance sizes like kb, Mb, GB, etc.

<table class="sortable">
  <thead>
    <tr>
      <th>Movie Name</th>
      <th>Size</th>
      <th>Release date</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Zack Snyder's Justice League</td>
      <td data-sort="943718400">900MB</td>
      <td data-sort="20210318">03/18/2021</td>
    </tr>
    <tr>
      <td>The Sound of Music</td>
      <td data-sort="1610612736">1.5GB</td>
      <td data-sort="19651209">12/09/1965</td>
    </tr>
  </tbody>
</table>
