I am using datatables on my WordPress website. However, when I tried to use the custom filter for my age column, I got an error saying "Cannot read property 'ext' of undefined", how can I fix it?

    here is my code '''

            jQuery(document).ready(function() {
                var table = jQuery('#myTable').DataTable(
                    {
                        searchPane:{
                            columns:[':contains("Gender")',':contains("Birth Province")',':contains("story")',]
                            , threshold: 0
                        }
                    }
                );
    
                // Event listener to the two range filtering inputs to redraw on input
                jQuery('#min, #max').keyup( function() {
                    table.draw();
                } );
            } );
    
    
            jQuery.fn.dataTable.ext.search.push(
                            function( settings, data, dataIndex ) {
                                var min = parseInt( $('#min').val(), 10 );
                                var max = parseInt( $('#max').val(), 10 );
                                var age = parseFloat( data[6] ) || 0; // use data for the age column
    
                                if ( ( isNaN( min ) && isNaN( max ) ) ||
                                    ( isNaN( min ) && age <= max ) ||
                                    ( min <= age   && isNaN( max ) ) ||
                                    ( min <= age   && age <= max ) )
                                {
                                    return true;
                                }
                                return false;
                            }

    One problem is you are loading jquery.js more than once. You have it on line 52 then on line 326. You only want to load it once. Fixing this may solve your problem.

    Thorngren, thank you for replay.
    I have removed one but still doesn't work, do you have any other ideas?
    thanks

    Maybe jQuery.fn.dataTable.ext.search.push(...) on line 77 is being executed before you load datatables.js on line 327. You will want to execute it after Datables has been loaded. Maybe move all the JS includes starting at line 327 between line 53 and 54. Load order is important with Javascript.

    Thank you Kthorngren, that is the problem.
    However, My age filter still doesn't work and there is no error message, do you have any recommendations to fix it or to debug?
    Thank you again

    I don't see anything obvious. I would start with some console.log statements to debug the problem. I would start with placing one in the search plugin, for example:

              jQuery.fn.dataTable.ext.search.push(
                                function( settings, data, dataIndex ) {
                                    var min = parseInt( $('#min').val(), 10 );
                                    var max = parseInt( $('#max').val(), 10 );
                                    var age = parseFloat( data[6] ) || 0; // use data for the age column
    
                                    console.log(min, max, age);                     
    
                                    if ( ( isNaN( min ) && isNaN( max ) ) ||
                                        ( isNaN( min ) && age <= max ) ||
                                        ( min <= age   && isNaN( max ) ) ||
                                        ( min <= age   && age <= max ) )
                                    {
                                        return true;
                                        
                                    }
                                    return false;
                                    
                                }
                            );
    

    This will show that your keyup event is working and the values being compared. Should lead you to the next troubleshooting steps.
