首先我认为这是 JS 问题，但这是皮肤问题。
并且提到这个问题发生在 Chome 和 FF 上，但在 IE 中它出于某种原因工作。
我是第一次为DNN设计皮肤，它一直很好，直到我发现我做错了什么:(。
我创建了一个简单的皮肤，在内容窗格中。在该内容窗格中，我添加了自定义模块，当用户滚动到页面底部时动态加载元素（我将新元素附加到 div）。
而且我的模块在“ DarkKnightSkin”上运行良好，但在我的自定义皮肤上，我认为我错过了一些东西，所以欢迎任何帮助:)
问题是当我滚动到底部时没有任何反应。但是当我滚动到顶部时，它会触发动作并做它需要做的事情。我在这里做错了什么？
这是皮肤.ascx
<div id="wrapper">
<header>
<div id="top-bar-menu">
<div id="top-bar-menu-logo-holder">
<dnn:LOGO runat="server" ID="dnnLOGO" />
</div>
<div id="user-account-box" style="position: absolute; top: 5px; right: 5px;">
<dnn:USER runat="server" ID="dnnUSER" />
<dnn:LOGIN runat="server" ID="dnnLOGIN" />
</div>
</div>
</header>
<nav>
<div id="main-navigation-menu">
<ddr:MENU ID="MENU1" MenuStyle="Superfish" runat="server">
<ClientOptions>
<ddr:ClientString Name="speed" Value="fast" />
</ClientOptions>
</ddr:MENU>
</div>
<div class="clear"></div>
</nav>
<div id="main-content-holder">
<div runat="server" id="ContentPane"></div>
</div>
</div>
这是皮肤.css

}
在我的模块中：
$(window).scroll(function () {
if ($(window).scrollTop() == $(document).height() - $(window).height() && !($('#imgLoad').is(':visible'))) {
loadMore();
}
});
更新
我创建了一个新的skin.asmx（skin.css空文件）并且只放了这个：
<%@ Control Language="vb" AutoEventWireup="false" Explicit="True" Inherits="DotNetNuke.UI.Skins.Skin" %>
<%@ Register TagPrefix="dnn" TagName="LOGO" Src="~/Admin/Skins/Logo.ascx" %>
<%@ Register TagPrefix="dnn" TagName="SOLPARTMENU" Src="~/Admin/Skins/SolPartMenu.ascx" %>
<%@ Register TagPrefix="dnn" TagName="PRIVACY" Src="~/Admin/Skins/Privacy.ascx" %>
<%@ Register TagPrefix="dnn" TagName="USER" Src="~/Admin/Skins/User.ascx" %>
<%@ Register TagPrefix="dnn" TagName="LOGIN" Src="~/Admin/Skins/Login.ascx" %>
<div runat="server" id="ContentPane"></div>
我的模块仍然可以正常渲染，但在滚动底部不起作用并且返回顶部工作（仍然反转）。
