向服务器回发表行索引/位置

Question

我创建了一个表格和一些jQuery，以按上下箭头图标的点击对表格行进行重新排序。这工作正常，所以现在我想将新职位发布回服务器，并保留并将其检索到数据库表中。要启用此功能，应该在服务器端创建哪些变量以准备接收数据，以及如何填充这些变量？

        $(".up,.down").click(function(){
            var row = $(this).parents("tr:first");
            if ($(this).is(".up")) {
                row.insertBefore(row.prev());
            } else {
                row.insertAfter(row.next());
            }
        });

                     <table class="noBorder" runat="server" id="tblOutcome">
                        <tr>                                
                            <td>
                                <a href="#" class="up"><img src="../../graphics/blue_up_arrow.gif" /></a>
                                <a href="#" class="down"><img src="../../graphics/blue_down_arrow.gif" /></a>
                            </td>
                            <td>Presentation</td>
                        </tr>
                        <tr>                                
                            <td>
                                <a href="#" class="up"><img src="../../graphics/blue_up_arrow.gif" /></a>
                                <a href="#" class="down"><img src="../../graphics/blue_down_arrow.gif" /></a>
                            </td>
                            <td>Investigation</td>
                        </tr>
                        <tr>                                
                            <td>
                                <a href="#" class="up"><img src="../../graphics/blue_up_arrow.gif" /></a>
                                <a href="#" class="down"><img src="../../graphics/blue_down_arrow.gif" /></a>
                            </td>
                            <td>Diagnosis</td>
                        </tr>
                        <tr>
                            <td>
                                <a href="#" class="up"><img src="../../graphics/blue_up_arrow.gif" /></a>
                                <a href="#" class="down"><img src="../../graphics/blue_down_arrow.gif" /></a>
                            </td>
                            <td>Staging</td>
                        </tr>
                    </table>
