Jquery Datatables Export按钮上是否有回调？

Question

So I just implemented jquery datatables and added the export buttons. I was wondering if there are any callbacks on export. Let say I have a list of items in the database that i am showing in the datatable and I want to remove them from the database after i have exported them.

Please any help is appreciated.

No not as far as I know. But you can create your own custom Button and define an action for it. Inside that action you can call the export function and afterwards do whatever you are up to.

new $.fn.dataTable.Buttons( table, {
    buttons: [
        {
            text: 'Create CSV',
            action: function ( e, dt, node, config ) {     
                // Call the default csvHtml5 action method to create the CSV file
                $.fn.dataTable.ext.buttons.csvHtml5.action.call(this, e, dt, node, config);                 

                // Do custom processing
                alert('Other stuff');
            }
        }
    ]
} );
