Question

我有以下布局页面

_StyledLayout.cshtml：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />


    <title>@ViewBag.Title</title>

    <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

    @RenderSection("Head", false)
</head>
<body>
    @RenderBody()
</body>
</html>

_StyledPageLayout.cshtml：

@{
    Layout = "~/Views/Shared/_StyledLayout.cshtml";
}

@section Head
{
<script src="@Url.Content("~/Scripts/jquery-ui.min.js")" type="text/javascript"></script>

}

@RenderBody()

Details.cshtml：

@using System.Data;

@model ASPNETMVC3.Models.ConfigModel
@{
    ViewBag.Title = "Details";
    Layout = "~/Views/Shared/_StyledPageLayout.cshtml";
}

@section Head
{
<script type="text/javascript">

        var oTable;

        $(document).ready(function () {  

            $(".datepicker").datepicker({ dateFormat: 'dd/mm/yy' });

        });

    </script>
}

<h2>
    Details</h2>

在此设置中，当我转到详细信息时，我收到错误： *以下部分已定义，但尚未针对布局页面“〜/ Views / Shared / _StyledPageLayout.cshtml”呈现：“Head” *

我做错了什么？

Answer 1

_StyledPageLayout.cshtml：

@section Head
{
    @if (IsSectionDefined("Head"))
    {
        // If the view contains a Head section use that instead
        @RenderSection("Head")
    }
    else
    {
        // The view doesn't have a Head section => use some default output
        <script src="@Url.Content("~/Scripts/jquery-ui.min.js")" type="text/javascript"></script>
    }
}

Answer 2

基本上与已接受的答案相同，但如果您不需要默认渲染，则会更整洁......

@section Head
{
   @RenderSection("Head", false)
}

...其中'false'表示该部分不是必需的。

嵌套/继承布局页面无效
