Question

我尝试这样做的主要动机是获取Javascript，只需要页面底部的部分Javascript以及其他Javascript，而不是在部分呈现的页面中间。

以下是我正在尝试做的简化示例：

这是在正文之前有一个Scripts部分的布局。

<!DOCTYPE html>
<html>
<head>
    <title>@ViewBag.Title</title>
    <link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />    
</head>

<body>
    @RenderBody()
    <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script>
    @RenderSection("Scripts", false)
</body>
</html>

以下是使用此布局的示例视图。

<h2>This is the view</h2>

@{Html.RenderPartial("_Partial");}

@section Scripts {
<script type="text/javascript">
        alert("I'm a view.");
</script>
}

这是从视图中呈现的部分内容。

<p>This is the partial.</p>

@* this never makes it into the rendered page *@
@section Scripts {
<script type="text/javascript">
    alert("I'm a partial."); 
</script>
}

在此示例中，视图中指定的标记放在该部分中，但部分中的标记不放置。是否可以使用Razor从局部视图填充部分？如果没有，那么获取Javascript的其他方法是什么？页面底部的部分只需要它而不是全局包含它？

Answer 1

我处理这个问题的方法是在HtmlHelper类中编写几个扩展方法。这允许局部视图说它们需要一个脚本，然后在布局视图中写入我调用我的帮助器方法的标签来发出所需的脚本

以下是辅助方法：

public static string RequireScript(this HtmlHelper html, string path, int priority = 1)
{
    var requiredScripts = HttpContext.Current.Items["RequiredScripts"] as List<ResourceInclude>;
    if (requiredScripts == null) HttpContext.Current.Items["RequiredScripts"] = requiredScripts = new List<ResourceInclude>();
    if (!requiredScripts.Any(i => i.Path == path)) requiredScripts.Add(new ResourceInclude() { Path = path, Priority = priority });
    return null;
}

public static HtmlString EmitRequiredScripts(this HtmlHelper html)
{
    var requiredScripts = HttpContext.Current.Items["RequiredScripts"] as List<ResourceInclude>;
    if (requiredScripts == null) return null;
    StringBuilder sb = new StringBuilder();
    foreach (var item in requiredScripts.OrderByDescending(i => i.Priority))
    {
        sb.AppendFormat("<script src=\"{0}\" type=\"text/javascript\"></script>\n", item.Path);
    }
    return new HtmlString(sb.ToString());
}
public class ResourceInclude
{
    public string Path { get; set; }
    public int Priority { get; set; }
}

完成后，部分视图只需拨打@Html.RequireScript("/Path/To/Script")。

在布局视图的标题部分中，您可以调用@Html.EmitRequiredScripts()。

这样做的一个额外好处是，它允许您清除重复的脚本请求。如果您有多个需要给定脚本的视图/部分视图，您可以放心地假设您只输出一次

Answer 2

部分视图无法参与其父视图的部分。

Answer 3

你可能有第二部分只负责注入必要的javascript。如果需要，可以在@if块周围放置几个脚本：

@model string
@if(Model == "bla") {
    <script type="text/javascript">...</script>
}

@else if(Model == "bli") {
    <script type="text/javascript">...</script>
}

这显然可以稍微清理一下，但是，在视图的Scripts部分：

@section Scripts
{
    @Html.Partial("_Scripts", "ScriptName_For_Partial1")
}

同样，它可能不会赢得美容奖，但它会起作用。

Answer 4

更优雅的方法是将部分视图脚本移动到单独的文件中，然后在视图的脚本部分中呈现它：

<h2>This is the view</h2>

@Html.RenderPartial("_Partial")

@section Scripts
{
    @Html.RenderPartial("_PartialScripts")

    <script type="text/javascript">
        alert("I'm a view script.");
    </script>
}

部分视图_ Partial.cshtml ：

<p>This is the partial.</p>

仅包含脚本的部分视图_ PartialScripts.cshtml ：

<script type="text/javascript">
    alert("I'm a partial script!");
</script>

Answer 5

安装 Forloop.HtmlHelpers nuget包 - 它添加了一些帮助程序来管理部分视图和编辑器模板中的脚本。

在布局的某个地方，您需要致电

@Html.RenderScripts()

这将是页面中输出任何脚本文件和脚本块的位置，因此我建议将其放在布局中的主脚本之后以及脚本部分之后（如果有的话）。

如果您正在使用捆绑的Web优化框架，则可以使用重载

@Html.RenderScripts(Scripts.Render)

这样该方法用于写出脚本文件。

现在，只要您想在视图，局部视图或模板中添加脚本文件或块，只需使用

@using (Html.BeginScriptContext())
{
  Html.AddScriptFile("~/Scripts/jquery.validate.js");
  Html.AddScriptBlock(
    @<script type="text/javascript">
       $(function() { $('#someField').datepicker(); });
     </script>
  );
}

帮助程序确保如果多次添加，则只呈现一个脚本文件引用，并且还确保脚本文件以预期顺序呈现出来，即

布局
部分和模板（按照它们在视图中显示的顺序，从上到下）

我的2美分，这是一个旧帖子，但仍然相关，所以这里是贝尔先生的解决方案的升级更新，与ASP.Net Core一起使用。

它允许从导入的部分视图和子视图向主布局添加脚本和样式，并可以向脚本/样式导入添加选项（如异步延迟等）：

public static class ScriptsExtensions
{
    const string REQ_SCRIPT = "RequiredScript";
    const string REQ_STYLE = "RequiredStyle";

    public static string RequireScript(this IHtmlHelper html, string path, int priority = 1, params string[] options)
    {

        var requiredScripts = ctxt.Items[REQ_SCRIPT] as List<ResourceInclude>;
        if (requiredScripts == null) ctxt.Items[REQ_SCRIPT] = requiredScripts = new List<ResourceInclude>();
        if (!requiredScripts.Any(i => i.Path == path)) requiredScripts.Add(new ResourceInclude() { Path = path, Priority = priority, Options = options });
        return null;
    }

        }
        return new HtmlString(sb.ToString());
    }


    public static string RequireStyle(this IHtmlHelper html, string path, int priority = 1, params string[] options)
    {

对于正在寻找aspnet core 2.0版本的用户：

    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using Microsoft.AspNetCore.Html;
    using Microsoft.AspNetCore.Http;

    public static class HttpContextAccessorExtensions
    {
        public static string RequireScript(this IHttpContextAccessor htmlContextAccessor, string path, int priority = 1)
        {
            var requiredScripts = htmlContextAccessor.HttpContext.Items["RequiredScripts"] as List<ResourceInclude>;
            if (requiredScripts == null) htmlContextAccessor.HttpContext.Items["RequiredScripts"] = requiredScripts = new List<ResourceInclude>();
            if (requiredScripts.All(i => i.Path != path)) requiredScripts.Add(new ResourceInclude() { Path = path, Priority = priority });
            return null;
        }

        public static HtmlString EmitRequiredScripts(this IHttpContextAccessor htmlContextAccessor)
        {
            var requiredScripts = htmlContextAccessor.HttpContext.Items["RequiredScripts"] as List<ResourceInclude>;
            if (requiredScripts == null) return null;
            StringBuilder sb = new StringBuilder();
            foreach (var item in requiredScripts.OrderByDescending(i => i.Priority))
            {
                sb.AppendFormat("<script src=\"{0}\" type=\"text/javascript\"></script>\n", item.Path);
            }
            return new HtmlString(sb.ToString());
        }
        public class ResourceInclude
        {
            public string Path { get; set; }
            public int Priority { get; set; }
        }
    }

在脚本渲染部分调用后添加到布局：

@HttpContextAccessor.EmitRequiredScripts()

在您的局部视图中：

@inject IHttpContextAccessor HttpContextAccessor

...

@HttpContextAccessor.RequireScript("/scripts/moment.min.js")

使用回复https://stackoverflow.com/a/18790222/1037948的@using(Html.Delayed()){ ...your content... }个扩展程序，以便稍后在页面中呈现任何内容（脚本或HTML）。内部Queue应确保正确排序。

此功能也在ClientDependency.Core.Mvc.dll中实现。它提供了html助手：@ Html.RequiresJs和@ Html.RenderJsHere（）。 Nuget包：ClientDependency-Mvc

Answer 11

您可以创建一个新的Layout页面并将PartialView包装在一个完整视图中，该视图负责呈现内容以及任何库部分。

例如，假设我有以下代码：

<强> HomeController.cs

[HttpGet]
public ActionResult About()
{
    var vm = new AboutViewModel();
    return View("About", vm);
}

渲染“整页”视图时，通常会通过合并两个文件来渲染它们：

<强> About.cshtml

@model AboutViewModel

@{
    ViewBag.Title = "About CSHN";
}

<h3>@ViewBag.Title</h3>

@section Styles {
    <style> /* style info here */ </style>
}

@section Scripts {
    <script> /* script info here */ </script>
}

_Layout.cshtml ^{（或_ViewStart中指定或在页面中覆盖的任何内容）}

<!DOCTYPE html>

<html>
<head>
    @RenderSection("Styles", false)
    <title>@ViewBag.Title</title>
</head>
<body>
    @RenderBody()

    @RenderSection("scripts", false)
</body>
</html>

现在，假设您想将 About.cshtml 渲染为部分视图，可能作为响应AJAX调用的模态窗口。这里的目标是仅返回about页面，脚本和所有内容中指定的内容，而不会在_Layout.cshtml主布局中包含所有膨胀（如完整的<html>文档）。

您可以尝试这样做，但不会出现任何部分块：

return PartialView("About", vm);

相反，添加一个更简单的布局页面如下：

<强> _PartialLayout.cshtml

<div>
    @RenderBody()
    @RenderSection("Styles", false)
    @RenderSection("scripts", false)
</div>

或支持这样的模态窗口：

<强> _ModalLayout.cshtml

<div class="modal modal-page fade" tabindex="-1" role="dialog" >
    <div class="modal-dialog modal-lg" role="document">
        <div class="modal-content">

            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                <h4 class="modal-title">@ViewBag.Title</h4>
            </div>

            <div class="modal-body">

                @RenderBody()
                @RenderSection("Styles", false)
                @RenderSection("scripts", false)

            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-inverse" data-dismiss="modal">Dismiss</button>
            </div>
        </div>
    </div>
</div>

然后您可以在此控制器中specify a custom Master View或您想要同时呈现视图的内容和脚本的任何其他处理程序

[HttpGet]
public ActionResult About()
{
    var vm = new AboutViewModel();
    return !Request.IsAjaxRequest()
              ? View("About", vm)
              : View("About", "~/Views/Shared/_ModalLayout.cshtml", vm);
}

Answer 12

这是我解决常见问题“如何将部分视图中的部分注入到asp.net mvc的主视图或主布局视图？”的解决方案。如果您通过关键字“section + partial”搜索stackoverflow，您将获得相关问题的大量列表，并给出答案，但通过剃刀引擎语法，它们中没有一个看起来优雅。所以我只看一下Razor引擎，看看是否可以找到更好的解决方案。

幸运的是，我发现Razor引擎如何为视图模板文件（* .cshtml，* .vbhtml）进行编译，这对我来说很有趣。（我稍后会解释），下面是我的解决方案代码，我认为它的使用非常简单和优雅。

namespace System.Web.Mvc.Html
{
    public static class HtmlHelperExtensions
    {
        /// <summary>

用法：使用代码也非常简单，它看起来与通常的风格几乎相同。它还支持嵌套部分视图的任何级别。即。我有一个视图模板链：_ViewStart.cshtml-＆gt; layout.cshtml-＆gt; index.cshtml-＆gt; [head.cshtml，foot.cshtml] - ＆gt; ad.cshtml。

在layout.cshtml中，我们有：

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title>@ViewBag.Title - @ViewBag.WebSetting.Site.WebName</title>
    <base href="@ViewBag.Template/" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
    <meta http-equiv="Cache-Control" content="no-siteapp" />
    <meta name="viewport" content="width=device-width, initial-scale=1,maximum-scale=1.0, user-scalable=0,user-scalable=no">
    <meta name="format-detection" content="telephone=no">
    <meta name="renderer" content="webkit">
    <meta name="author" content="Taro Technology Co.,LTD" />
    <meta name="robots" content="index,follow" />
    <meta name="description" content="" />
    <meta name="keywords" content="" />
    <link rel="alternate icon" type="@ViewBag.WebSetting.Site.WebFavIcon" href="@ViewBag.WebSetting.Site.WebFavIcon">
    @Html.RenderSectionEx("Head")
</head>
<body>
    @RenderBody()
    @Html.RenderSectionEx("Foot")
</body>
</html>

在index.cshtml中，我们有：

@{
    ViewBag.Title = "首页";
}

@Html.Partial("head")
<div class="am-container-1">
    .......
</div>
@Html.Partial("foot")

在head.cshtml中，我们会得到代码：

@section Head{
    <link rel="stylesheet" href="assets/css/amazeui.css" />
    <link rel="stylesheet" href="assets/css/style.css" />
}

<header class="header">
   ......
</header>
@Html.EnsureSection()

在foot.cshtml或ad.cshtml中是相同的，你仍然可以在其中定义Head或Foot部分，确保在部分视图文件的末尾调用@ Html.EnsureSection（）一次。这就是你需要做的就是摆脱asp mvc中的遭遇问题。

我只是分享我的代码段，以便其他人可以使用它。如果您认为它有用，请不要犹豫，评价我的帖子。：）
