You need ScriptManager if you want to call pageLoad . 如果要调用pageLoad，则需要ScriptManager 。
<asp:ScriptManager runat="server" ID="ScriptManager1" />
<script type="text/javascript"
src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
function pageLoad() {
$('#menu').hide();
}
</script>
Since you are using jQuery, you can use the following - 由于您使用的是jQuery，因此可以使用以下命令 -
<script type="text/javascript"
src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$('#menu').hide();
});
</script>
Another Approach using Server Side Code 使用服务器端代码的另一种方法
You can create Menu as Server Control , and access it from dashboard codebehind. 您可以将菜单创建为服务器控件 ，并从仪表板代码隐藏中访问它。
Site.Master 的Site.Master
<div class="container">
<div>
<div class="navbar navbar-default" role="navigation">
<asp:Panel runat="server" ID="MenuPanel"
CssClass="navbar-collapse collapse">
<ul class="nav navbar-nav navbar-right alert-success">
<li class="active"><a href="Default.aspx">Home</a></li>
</ul>
</asp:Panel>
</div>
</div>
<asp:ContentPlaceHolder ID="MainContent" runat="server" />
</div>
Site.Master.cs Site.Master.cs
public partial class Site : System.Web.UI.MasterPage
{
public bool MenuPanelVisible
{
set { MenuPanel.Visible = value; }
}
}
dashboard.aspx.cs dashboard.aspx.cs
public partial class dashboard : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
var master = Master as Site;
if (master != null)
{
master.MenuPanelVisible = false;
}
}
}

check your HTML. 检查你的HTML。 if i am not mistaken, the ID will not be generated to HTML 1:1. 如果我没有弄错，则不会生成HTML 1：1的ID。
also currently your JS will not be executed... on the other hand you can define server-sided code too: 目前您的JS也不会被执行...另一方面，您也可以定义服务器端代码：
<script language="C#" runat="server" type="text/c#">
public void Page_Load(object sender, EventArgs e){
//hide the menu here
}
</script>
alternatively you could even do the following: 或者你甚至可以做以下事情：
<div id="menu" onload="this.visibility=hidden;"></div>

You need to put your pageLoad functionality in the jQuery document ready handler so it executes after the DOM has loaded. 您需要将pageLoad功能放在jQuery文档就绪处理程序中，以便在DOM加载后执行。
It should look something like this: 它应该看起来像这样：
<script type="text/javascript">
$(document).ready(function() {
$('#menu').hide();
});
</script>
