我很难找到答案，但没有成功。当按下按钮时，三个 div 应该以不同的速度/时间淡入。发生的情况是，当按下按钮时，页面似乎开始显示三个 div，但随后立即切换回来，导致它们从未真正出现。当我在不使用 masterpagefile 的常规 html 或 asp 页面中使用它时，它可以工作。Javascript 错误控制台不报告任何错误。代码如下：

switch_forms.aspx

    <%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="switch_forms.aspx.cs" Inherits="swithforms.switch_forms" %>

   <asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">

   </asp:Content>
   <asp:Content ID="Content2" ContentPlaceHolderID="FeaturedContent" runat="server">
   </asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="server">
<script>
    function switchForm() {
        $("#div1").fadeIn();
        $("#div2").fadeIn("slow");
        $("#div3").fadeIn(3000);
    };

</script>
<p>Demonstrate fadeIn() with different parameters.</p>
<button id="button" onclick="switchForm()">Click to fade in boxes</button>
<br><br>
<div id="div1" style="display: none;">
    <p>div1</p>
</div>
<br>
<div id="div2" style="display: none;">
    <p>div2</p>
</div><br>
<div id="div3" style="display: none;">
    <p>div3</p>
</div>
</asp:Content>

它一定与 .net 项目如何使用/加载母版页内容有关，但我太笨了，不知道。非常感谢您的帮助。谢谢！

该按钮可能导致回发，尝试阻止这样的默认操作：

function switchForm(event) {
    event.preventDefault();
    $("#div1").fadeIn();
    $("#div2").fadeIn("slow");
    $("#div3").fadeIn(3000);
};

和你的处理程序，event作为参数添加：

onclick="switchForm(event)"
