优化和省略一些jQuery额外代码并保留所有好处

Question

让我写下一些代码来更清楚地解释我的问题，我有一个Asp DataList如下：

<asp:DataList ID="DataList1" runat="server" BorderWidth="0px" CellPadding="0" CellSpacing="0"
                        RepeatColumns="1" RepeatDirection="Vertical" ShowFooter="False" ShowHeader="False"
                        Width="100%">
                        <ItemTemplate>                            
                            <table border="0" cellpadding="0" cellspacing="0" width="100%" style="height: 100%;" id='<%: "HomeSectionID" + Session["Counter"].ToString() %>'>
                                <tr>
                                    <td style="width: 70%;">
                                        <asp:Label ID="Label3" runat="server" Font-Bold="True" Font-Size="10pt" class="SpTitle"
                                            Style="display: none;"><%: Title %></asp:Label>
                                        نام محصول :

                                        <br />

                                        <asp:Label ID="Label2" runat="server" CssClass="prod-black-text" SkinID="BestSellsImageaspLabel1skin"
                                            Text='<%# Bind("GoodExplain1") %>'></asp:Label>
                                        <div class="ShortDescriptionBestSales" style="display: none;">
                                            <asp:Label ID="aspLabelText1" runat="server" Text='<%# Bind("Text1") %>'></asp:Label><br />
                                            قيمت :
                                            <asp:Label ID="aspLabel1" runat="server" CssClass="prod-black-text" SkinID="BestSellsImageaspLabel1skin"
                                                Text='<%# Bind("MaxSellPrice") %>'></asp:Label>
                                        </div>
                                    </td>
                                    <td style="width: 30%; vertical-align: middle;">
                                        <asp:Image ID="Image13" runat="server" Height="62px" 
                                            ImageUrl='<%# Eval("image") %>' />
                                    </td>
                                </tr>
                            </table>
                            <% int counter = int.Parse(Session["Counter"].ToString());
                               counter++;
                               Session["Counter"] = counter;
                                %>
                        </ItemTemplate>
                    </asp:DataList>

在javascript文件中我有一些jquery代码：

    old_color = $(this).css("background-color");
    if (old_color != "#cccccc")
        $(this).css("background-color", "#e8e8eb");

    $("#HomeSectionID10").css("background-color", "#ffffff");
    $("#HomeSectionID11").css("background-color", "#ffffff");
});

注意：datalist和datalist中有三行封装在.ascx控制文件中 主页面中的每个控件都由不同的服务器端属性重复四次，因此有12个HomeSection全部按会话值设置。

如何在不改变性能和外观的情况下优化我的jquery代码？
