Q:

How to change table's page length dynamically

Is there a way to change the pageLength setting of the dataTable on runtime within the "window.resize" event of jQuery?
These are the dataTable settings I'm using
$('#dataTable').DataTable({
    paging: true,
    pageLength: 35,
    searching: true,
    lengthChange: false,
    info: false,
    scrollCollapse: true,
    scrollY: "calc(74vh)"
});

I want the pageLength to change, whenever the window is resized.
I'm trying this
$(window).resize(function () {
    if ($(this).height() >= "1080"){
        // change the dataTable pageLength in here
        $('#dataTable').DataTable({ pageLength: 50 });
    } else {
        // default pageLength
        $('#dataTable').DataTable({ pageLength: 35 });
    }
});

A:

Use page.len() API function to change page length dynamically.
$(window).resize(function () {
    if ($(this).height() >= 1080){
        // change the dataTable pageLength in here
        $('#dataTable').DataTable().page.len(50).draw();
    } else {
        // default pageLength
        $('#dataTable').DataTable().page.len(35).draw();
    }
});
