Change the number of displayed rows in jQuery datatable

Question

Why the number of rows in jquery datatable (see the code below) is not set to 5? It is equal to 10 8as by default). Why \'iDisplayLength\': 5 does

Answer 1

This is definetely the easiest way I found:

var oTable;

$(document).ready(function() {
    $('.some-button').click( function () {
        var oSettings = oTable.fnSettings();
        oSettings._iDisplayLength = 50;
        oTable.fnDraw();
    });

    oTable = $('#example').dataTable();
});
