  You can use the count() API to get the number of rows. The examples should get you started.

  I have to visualize the result of the record also in the web page, in a point I specified in the code

  this
  ) id="perftabs"> Performer Credits (row result) )

  You would use something like this:

  var table = $('#example').DataTable();
   
  var numRows = table.rows( ).count();
  
  

  Then you would use jQuery or your preferred method to place the value of numRows on the web page. Something like this example:
  https://datatables.net/extensions/select/examples/api/get.html

  Now the question si when do you want to display that info? After a button click like the select example?

  After the Datatable has initialized? You could use initComplete, something like this:

  $('#example').dataTable( {
    "initComplete": function(settings, json) {
        var api = this.api();
        var numRows = api.rows( ).count();
        // Place the value in your HTML using jQuery, etc
    }
  } );

  Hi @Alex2019 ,

  We're happy to take a look, but as per the forum rules, please link to a test case - a test case that replicates the issue will ensure you'll get a quick and accurate response. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here.

  Cheers,

  Colin
