There is no common solution for this issue but you can do the following simplest ways:

1) You can create a set of extension method as the following:

2) Simply move your javascript codes into a separated partial view and on your main view, render 2 partial views. One for the main partial view and the other for your scripts as the following:

{
    // markup and razor code for Main View here

    @Html.Partial("Main_PartialView")
}

@section Scripts
{
    @Html.Partial("JavaScript_PartialView")
}

Hope it helps.

You can't render layout sections from a partial. Move the section definition to the parent page or layout.

Answer 3

If you want to include specific scripts only in some partial views and avoid spreading them unnecessarily throughout your application, you can do something like this:

Define a bundle pointing to an empty javascript file in your BundleConfig.cs:

 bundles.Add(new ScriptBundle("~/bundles/empty").Include(
                    "~/Scripts/empty.js"
            ));

In the head section of your _Layout.cshtml, add this variable:

@{
        ViewBag.AdditionalBundle = String.IsNullOrEmpty(ViewBag.AdditionalBundle) ? "~/bundles/empty" : ViewBag.AdditionalBundle;
    }

In the bottom of your _Layout.cshtml, render any additional bundles you want:

@Scripts.Render("~/bundles/lib")
    @Scripts.Render(@ViewBag.AdditionalBundle);
    @RenderSection("scripts", required: false)

And finally, in the partial view in which you need any specific scripts, just add the corresponding bundle to the variable:

ViewBag.AdditionalBundle = "~/bundles/mySpecificBundle";

Partial views are rendered before the _Layout.cshtml, so you need that verification at the top of the file. It goes like this: if any partial view assigned a value to ViewBag.AdditionalBundle, then use it. Otherwise, render an empty script.

Answer 4

You can add the script directly at the end of the partial view html, without script section (because script section is not rendered in partial views)

<script language="javascript">
   // Your scripts here
   // ....
</script>

Answer 5

You can use @Scripts.Render("~/Scripts/my-script.js") for .js files and @Styles.Render("~/Content/my-Stylesheet.css") for css files.

Nb: it works for a particular bundle also More details - 'http://www.asp.net/mvc/overview/performance/bundling-and-minification'

it works on any sub-pages in razor including partial views. for more info google for the usage of these helpers

This Stackoverflow page provided a full solution to this question: Using sections in Editor/Display templates

TL;DR: Just add the Forloop.HtmlHelpers nuget package https://www.nuget.org/packages/Forloop.HtmlHelpers/ to your project to allow you to run Javascript from Razor Partial Views and Templates in ASP.NET MVC. I have personally used this with my MVC 5 project.
