display row count in html page

Alex2019

I would like to count the number of rows and display the result in the html code

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

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) )

I now see below the table cells

the example I did not understand

kthorngren

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
  }
} );
