jQuery DataTables に列フィルターを追加しようとしています。しかし、出力が得られません。エラーも発生せず、コードが機能していない場所を推測できません。

追加したライブラリは次のとおりです。

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> 
<script src="http://localhost/codegen/assets/js/jquery.dataTables.js" type="text/javascript"></script>
<script src="http://localhost/codegen/js/jquery.dataTables.columnFilter.js" type="text/javascript"></script>

<style type="text/css">
    @import "http://localhost/codegen/assets/css/demo_table_jui.css";
    @import "http://localhost/codegen/assets/themes/smoothness/jquery-ui-1.8.4.custom.css";
</style>

jQuery コードは次のとおりです。

$(document).ready(function(){
        $('#datatables').dataTable({
            "sPaginationType":"full_numbers",
            "sScrollX": "100%",
            "bScrollCollapse": true,
            "bAutoWidth": true,
            "aaSorting":[[0, "asc"]],
            "bJQueryUI":true
             // Adding the filters equal to the no of columns
        }).columnFilter({
            aoColumns: [ { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  },
                         { type: "select", values: [ 'Gecko', 'Trident', 'KHTML', 'Misc', 'Presto', 'Webkit', 'Tasman']  }
                ]
        });
    })

誰が何が問題なのか/どこが間違っているのか教えてもらえますか? エラーも出力もありません。

前もって感謝します。NC

この URL ( http://www.datatables.net/release-datatables/examples/api/multi_filter_select.html ) の Datatable プラグイン Web サイトを見ると、間違った方向に進んでいるように見えます。

<SELECT>datatable の列でデータ フィルタリングを実行するために追加することは次のとおりです。

(function($) {
/*
 * Function: fnGetColumnData
 * Purpose:  Return an array of table values from a particular column.
 * Returns:  array string: 1d data array
 * Inputs:   object:oSettings - dataTable settings object. This is always the last argument past to the function
 *           int:iColumn - the id of the column to extract the data from
 *           bool:bUnique - optional - if set to false duplicated values are not filtered out
 *           bool:bFiltered - optional - if set to false all the table data is used (not only the filtered)
 *           bool:bIgnoreEmpty - optional - if set to false empty values are not filtered from the result array
 * Author:   Benedikt Forchhammer <b.forchhammer /AT\ mind2.de>
 */
$.fn.dataTableExt.oApi.fnGetColumnData = function ( oSettings, iColumn, bUnique, bFiltered, bIgnoreEmpty ) {
    // check that we have a column id
    if ( typeof iColumn == "undefined" ) return new Array();

    // by default we only want unique data
    if ( typeof bUnique == "undefined" ) bUnique = true;

    // by default we do want to only look at filtered data
    if ( typeof bFiltered == "undefined" ) bFiltered = true;

    // by default we do not want to include empty values
    if ( typeof bIgnoreEmpty == "undefined" ) bIgnoreEmpty = true;

    // list of rows which we're going to loop through
    var aiRows;

    // use only filtered rows
    if (bFiltered == true) aiRows = oSettings.aiDisplay;
    // use all rows
    else aiRows = oSettings.aiDisplayMaster; // all row numbers

    // set up data array   
    var asResultData = new Array();

    for (var i=0,c=aiRows.length; i<c; i++) {
        iRow = aiRows[i];
        var aData = this.fnGetData(iRow);
        var sValue = aData[iColumn];

        // ignore empty values?
        if (bIgnoreEmpty == true && sValue.length == 0) continue;

        // ignore unique values?
        else if (bUnique == true && jQuery.inArray(sValue, asResultData) > -1) continue;

        // else push the value onto the result data array
        else asResultData.push(sValue);
    }

    return asResultData;
}}(jQuery));


function fnCreateSelect( aData )
{
    var r='<select><option value=""></option>', i, iLen=aData.length;
    for ( i=0 ; i<iLen ; i++ )
    {
        r += '<option value="'+aData[i]+'">'+aData[i]+'</option>';
    }
    return r+'</select>';
}


$(document).ready(function() {
    /* Initialise the DataTable */
    var oTable = $('#example').dataTable( {
        "oLanguage": {
            "sSearch": "Search all columns:"
        }
    } );

    /* Add a select menu for each TH element in the table footer */
    $("tfoot th").each( function ( i ) {
        this.innerHTML = fnCreateSelect( oTable.fnGetColumnData(i) );
        $('select', this).change( function () {
            oTable.fnFilter( $(this).val(), i );
        } );
    } );
} );
