Change action performed by selecting page length from the length menu

nwicki

Hi

I am trying to overwrite the action performed when choosing a value in the length menu. The standard action is to adjust the amount of entries shown, but I'd rather perform a different action like updating the whole data set on which the table depends upon. Is there a way to adjust that action?

Thanks for your time.

Always good to take a look at the list of data tables events:
https://datatables.net/reference/event/

Particularly this one shoud be helpful:
https://datatables.net/reference/event/page

This one looks even better for your purpose:
https://datatables.net/reference/event/length

You could do this for example:

var table = $('#example').dataTable();
 
table.on( 'length', function ( e, settings, len ) {
    table.ajax.reload( null, false ); // user paging is not reset on reload
} );
