How do I regist JS with ASP.NET MVC?

Question

I want build a MVC Custom Control.

Now I have a problem.

My control has a file of js and a file of css.

I only want the page which used the control load the js and the css

and if i use this control maney times the js and css load once.

I know we can do like this in web form: ClientScript.RegisterClientScriptResource(typeof(..), "Assembly.MyScript.js");

but how can i do this in mvc??

there are two problem:

1.I want build a control to use in my project just like this @html.mycontrol() and the person who use it do not care any other(do not care if js or css load)

2.this control may use in other project.so i do not want the the other project know how to get the controls js or css(i Write this control in class liberary)

You control your includes through BundleConfig in MVC.

Normally, all bundles are loaded in the _Layout.cshtml document, like this:

@Scripts.Render("~/bundles/jquery")
@Styles.Render("~/Content/css")

You can make a custom bundle in the BundleConfig.cs file like this:

            bundles.Add(new ScriptBundle("~/bundles/nameOfBundle").Include(
                    "~/pathToFile"));

And then you just load the bundle in the file you need them in, instead of in the Layout.cshtml file.

I think you might be refering to custom HTML helpers. You can read this article about exactly that:blogs.technet.com/b/sateesh-arveti/archive/2013/09/06/…
