title: jQuery DataTables filter multiple tables
body: <p>I am using jQuery DataTables in some of my HTML tables. Well, I have a page where I list severral tables and I have to filter all of them by the same filters. In the case is a date range that I customized.</p>
  
  <p>All of the tables use the same css class to construct the dataTable and the search by date-range i did at </p>
  
  <pre><code>$.fn.dataTableExt.afnFiltering.push(fn).
  </code></pre>
  
  <p>I also have another search by text, using</p>
  
  <pre><code>$('.dataTable').dataTable().fnFilter(
      searchVal,
      4,
      false,
      true
  );
  </code></pre>
  
  <p>and this one is also working in only one table, not in them all as I was expecting to be.</p>
  
  <p>Thanks,</p>
