jQuery Datatables和ColumnFilterWidget集成問題

Question

我正在嘗試將ColumnFilterWidget插件放置在Datatables表的標題中。

這是我在其中所做的更改：

        /**
        * Menu-based filter widgets based on distinct column values for a table.
        *
        * @class ColumnFilterWidgets
        * @constructor
        * @param {object} oDataTableSettings Settings for the target table.
        */
        var ColumnFilterWidgets = function( oDataTableSettings ) {
                var me = this;
                var sExcludeList = '';
//              me.$WidgetContainer = $( '<div class="column-filter-widgets"></div>' );
                me.$WidgetContainer = $( '<tr class="head"></tr>' );
                me.$MenuContainer = me.$WidgetContainer;
                me.$TermContainer = null;
                me.aoWidgets = [];
                me.sSeparator = '';
                if ( 'oColumnFilterWidgets' in oDataTableSettings.oInit ) {
                        if ( 'aiExclude' in oDataTableSettings.oInit.oColumnFilterWidgets ) {
                                sExcludeList = '|' + oDataTableSettings.oInit.oColumnFilterWidgets.aiExclude.join( '|' ) + '|';
                        }
                        if ( 'bGroupTerms' in oDataTableSettings.oInit.oColumnFilterWidgets && oDataTableSettings.oInit.oColumnFilterWidgets.bGroupTerms ) {
                                me.$MenuContainer = $( '<div class="column-filter-widget-menus"></div>' );
                                me.$TermContainer = $( '<div class="column-filter-widget-selected-terms"></div>' ).hide();
                        }
                }

                // Add a widget for each visible and filtered column
                $.each( oDataTableSettings.aoColumns, function ( i, oColumn ) {
                        var $columnTh = $( oColumn.nTh );
                        var $WidgetElem = $( '<th><div class="column-filter-widget"></div></th>' );
                        if ( oColumn.bVisible && sExcludeList.indexOf( '|' + i + '|' ) < 0 ) {
                                me.aoWidgets.push( new ColumnFilterWidget( $WidgetElem, oDataTableSettings, i, me ) );
                        }
                        me.$MenuContainer.append( $WidgetElem );
                } );
                if ( me.$TermContainer ) {
                        me.$WidgetContainer.append( me.$MenuContainer );
                        me.$WidgetContainer.append( me.$TermContainer );
                }
                oDataTableSettings.aoDrawCallback.push( {
                        name: 'ColumnFilterWidgets',
                        fn: function() {
                                $.each( me.aoWidgets, function( i, oWidget ) {
                                        oWidget.fnDraw();
                                } );
                        }
                } );

                return me;
        };

我在數據表中添加了一個額外的<tr class='head'> ，稍后我嘗試將過濾器附加到附加了它們的過濾器上，但是相反，它是在創建新的TR標簽，然后在其中添加過濾器。

我什至將數據表的dom更改為：dom： '<"clear">Cf<"clear">ltWrip',因此表元素應該在那里，以便可以將過濾器插入頭部。

如果有人需要它，就在這里。

在html使用for循環中添加<TR id='Filter.$i'>元素，並將計數器值附加到ID。 然后修改了column.filterwidget插件js

 var ColumnFilterWidgets = function( oDataTableSettings ) {
                var me = this;
                var sExcludeList = '';
                me.$WidgetContainer = $( '<div class="column-filter-widgets"></div>' );
                me.$MenuContainer = me.$WidgetContainer;
                me.$TermContainer = null;
                me.aoWidgets = [];
                me.sSeparator = '';

                if ( 'oColumnFilterWidgets' in oDataTableSettings.oInit ) {
                        if ( 'aiExclude' in oDataTableSettings.oInit.oColumnFilterWidgets ) {
                                sExcludeList = '|' + oDataTableSettings.oInit.oColumnFilterWidgets.aiExclude.join( '|' ) + '|';
                        }
                        if ( 'bGroupTerms' in oDataTableSettings.oInit.oColumnFilterWidgets && oDataTableSettings.oInit.oColumnFilterWidgets.bGroupTerms ) {
                                me.$MenuContainer = $( '<div class="column-filter-widget-menus"></div>' );
                                me.$MenuContainer = $( '<div class="column-filter-widget-menus"></div>' );
                                me.$TermContainer = $( '<div class="column-filter-widget-selected-terms"></div>' ).hide();
                        }
                }

                var cnt= 0;
                // Add a widget for each visible and filtered column
                $.each( oDataTableSettings.aoColumns, function ( i, oColumn ) {
                        var $columnTh = $( oColumn.nTh );
                        cnt ++;
                        var $WidgetElem = $( '<div class="column-filter-widget" id=col'+cnt+'></div>' );
                        if ( oColumn.bVisible && sExcludeList.indexOf( '|' + i + '|' ) < 0 ) {
                                me.aoWidgets.push( new ColumnFilterWidget( $WidgetElem, oDataTableSettings, i, me ) );
                        }
                        var Tcol = document.getElementById('A');
                                console.log('---------'+i);

                        //me.$MenuContainer.append( $WidgetElem );
                        $('#Filter'+i).append( $WidgetElem );
                } );

                if ( me.$TermContainer ) {
                        me.$WidgetContainer.append( me.$MenuContainer );
                        me.$WidgetContainer.append( me.$TermContainer );
                }
                oDataTableSettings.aoDrawCallback.push( {
                        name: 'ColumnFilterWidgets',
                        fn: function() {
                                $.each( me.aoWidgets, function( i, oWidget ) {
                                        oWidget.fnDraw();
                                } );
                        }
                } );

                return me;
        };

希望這可以幫助。
