How to return Javascript from an ASP.NET 5 MVC 6 controller action

Question

I need one Action return a JavaScript fragment.

In MVC 5 we have:

return JavaScript("alert('hello')");

but in MVC 6 we don´t.

Is there a way to do this now ?

Answer 1

This can be achieved by returning ContentResult ^MSDN

return Content("<script language='javascript' type='text/javascript'>alert('Hello world!');</script>");

or other way would be making use of ajax

return json(new {message="hello"});  

 $.ajax({
        url: URL,
        type: "POST",
        success: function(data){alert(data.message)},    
    });

Answer 2

I think we can implment JavaScriptResult ourselves since it is not supported officially. It is easy:

public class JavaScriptResult : ContentResult
{
    public JavaScriptResult(string script)
    {
        this.Content = script;
        this.ContentType = "application/javascript";
    }
}
