asp.net-mvc-3 – 以下部分已定义,但尚未为布局页面呈现

OK，我有这个代码：

@{
     Layout = "~/_Layout.cshtml";
     Page.Title = "Home";            
}

@section meta{
    <meta name="keywords" content="" />
    <meta name="description" content="" />
}

<h2>Html Content Here</h2>

@section footer {
    <script src="http://code.jquery.com/jquery-latest.min.js" charset="utf-8"></script>
    <script type="text/javascript">
        $(document).ready(function() {
    });    
    </script> 
}
