这个简单的功能如何实现，

 <asp:Repeater ID="RepMenus" runat="server">

    <ItemTemplate>

    <li><span>

          <asp:HyperLink ID="HyperLink1" runat="server" MenusID='<%#Eval("id") %>'><%#Eval("Name") %></asp:HyperLink>

    </span></li>

        

    </ItemTemplate>

    </asp:Repeater>

        public  void Content(string Nid)

        {

            this.repNewContents.DataSource = null;

            repNewContents.DataSource = WEB_Business.B_News.getNewsData(Nid);

            repNewContents.DataBind();

        

        }





        protected void RepMenus_ItemCommand(object source, RepeaterCommandEventArgs e)

        {

         

   

            Content(e.CommandArgument.ToString());

            

        }

$(function () {

    $(".sideNav li").click(function () {

        $(this).find("a").addClass("sideNavOn");

        $(this).siblings().find("a").removeClass();

      

    });

});
