Problem extending print button

giulgiu

Hi,
I'm trying to extend the print button.
I've already implemeted to print only the selected row but I would also like to add an alert message containing some data of the selected row.
I've tried to do it but when I run the code it doesn't work.

This is what I've wrote:

$(document).ready(function () {
                    var table = $('#prescriptionsTable').DataTable({
                        dom: 'Bfrtip',
                        buttons: ['pdf',{
                            extend: 'print',
                            text: 'Print selected',
                            action: function(e, dt, button, config) {
                                var data = table.rows( { selected: true } ).data();
                                alert("Patient: " + data[0] + "\nDoctor: " + data[1]);
                                $.fn.dataTable.ext.buttons.print.action(e, dt, button, config);
                            }
                        }
                    ],
                    select: true
});

What is wrong with the actions I've inserted?
Thanks in advance!

I've tried to do it but when I run the code it doesn't work.

What specifically does it do or don't do?

Do you get errors in the browser's console.

Please create a simple test case replicating the issue to help debug the issue.

My bad, there was just a missing comma after the } of action.
Thnaks for your reply, it helped me indentify the problem.
