Is it possible to obtain the download progress of an dynamically loaded javascript file?

I'd like to load a basic homepage for a web-app which asynchronously loads a large javascript file (the guts of the application).

Can I retrieve the download progress of this js file?

I would like to display a loading bar that accurately reflects the download progress, then when the script has finished enable a 'launch' button.

I normally use jquery but am happy for any solutions! I'll be using a php backend if that helps.

This won't work on all browsers, but you can use the <progress> tag in HTML5.

You can also use the progress event for the connection.
