我正在使用具有包含 javascript 和 css 代码的 head 标签的母版页。它在本地服务器上运行良好，但是当文件托管时它会出错

我添加了 runat ="server" 仍然遇到同样的错误

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

    <title>
        <asp:Literal ID="litTitle" runat="server"></asp:Literal>
    </title>

</head>
<body>
    <form id="form1" runat="server">

【解决方案1】：

试试这个解决方案

1.添加脚本管理器

<asp:ScriptManagerID="ScriptManager1"runat="server">
</asp:ScriptManager>

2。添加一个javascript函数

// Write following function which calls automatically
<script language="javascript" type="text/javascript">
        function show()
        {
              document.write("<head id="Head1" runat='server'></head>");
        }
</script>

最后一切正常。！！！
