Question

How To dynamically generate a JavaScript file in an ASP.NET application using C#?

Answer 1

To dynamically generate a JavaScript file in an ASP.NET application using C#, you can create an endpoint (such as an .ashx handler or a Web API endpoint) that generates the JavaScript content and sets the appropriate MIME type for JavaScript.

Answer 2

To dynamically generate a JavaScript file in an ASP.NET application using C#, create a controller action that returns the JavaScript content with the appropriate MIME type:

1. C# Controller Action:

public ActionResult GenerateScript()
{
    string jsContent = @"
        function showAlert() {
            alert('Dynamically generated JS!');
        }";
    return Content(jsContent, "application/javascript");
}
 

 2. Reference in View:

<script src="@Url.Action("GenerateScript", "Script")"></script>
 

This will serve a dynamic JavaScript file when the view is loaded.
