title: Get value data-colonne using jQuery
body: <p>I have n AJAX request and I need to get the value of <code>data-colonne</code> to send to my controller.</p>
  
  <pre><code>&lt;th class="text-left"&gt;
      &lt;span&gt;
          &lt;?php echo $colonne; ?&gt;  
          &lt;span  data-colonne="&lt;?php echo $v; ?&gt;" class="fa fa-chevron-down status-red" &gt;&lt;/span&gt;
  &lt;/th&gt;
  </code></pre>
  
  <pre class="lang-html prettyprint-override"><code>$.ajax({
      url: "/sortindex"
      data: {Value on my data-colonne},
      type: 'post',
      success: function(data) {
          console.log('ok');
      }
  });
  </code></pre>
