Question

The above yellow link does not provide a solutions to this. The correct answer is .siblings() which is not in any of the linked solutions

I am trying to select all td elements except for the one passed as $(this). What is the proper way to do this ?

I don't think the following works :

$(this).find(':not')

..since I am looking for all at the same DOM level as $(this).

<html>
  <head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
    <script type="text/javascript">
      $(document).ready(function() {
        
        $('a').click(function() {
          alert($(this).text());
        });
        
      });
    </script>
  </head>
  <body>
    
    <a>Apples</a><br />
    <a>Bananas</a><br />
    <a>Oranges</a><br />
    
  </body>
</html>

Just stating this to be clear that I am looking for a general solution, not one specific to this example. :)

Use the .not() method to exclude a previous jQuery selection. You can pass a selector to it, but also an existing element or jQuery object.

var others = $('td').not(this);

$('td').on('click', function() {
      $(this).css('color', 'red')
      $('td').not(this).css('color', 'blue');
  });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
  <tr><td>Cell1</td><td>Cell2</td></tr>
  <tr><td>Cell3</td><td>Cell4</td></tr>
  <tr><td>Cell5</td><td>Cell5</td></tr>
</table>

jQuery.not() reference

After seeing your update and the various comments, I start to think that you just want to get the siblings of this. If you just want an element's siblings, use jQuery's siblings() function. This function optionally accepts a selector to get only specific siblings. Anyway, siblings implicitly excludes this itself.

$('td').on('click', function() {
      $(this).css('color', 'red')
      $(this).siblings().css('color', 'blue');
  });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
  <tr><td>Cell1</td><td>Cell2</td></tr>
  <tr><td>Cell3</td><td>Cell4</td></tr>
  <tr><td>Cell5</td><td>Cell5</td></tr>
</table>
