Button extend copy with action

TomTom1

Hello,

I would like to add an action to a Copy button and keep the default comportement as well. I succedded for a Copy as HTML5 but the basic Copy did generate an issue ($.fn.dataTable.ext.buttons.copy.action being undefined).
A scenario has been uploaded in a zip.
Can you tell me how to solve this case ?
Thank you in advance.

Regards.

In the action for the button you should be able to do something like:

new $.fn.dataTable.Buttons( table, {
    buttons: [
        { 
            extend: 'copy',
            action: function ( e, dt, node, config ) {
                // Do custom processing
                // ...
 
                // Call the default copyHtml5 action method to do the standard copy
                $.fn.dataTable.ext.buttons.copyHtml5.action.call(this, e, dt, node, config);
            }
        }
    ]
} );

See buttons.buttons.action.
