content-disposition

I am being asked to make a "download" button that downloads the contents of a textarea on the same page as a file, with the browser's "Save As" dialog showing up. Copy/paste would do the job just fine, but it is a "requirement".

Right now, I am just posting the contents of the textarea to the server, which echos them back with "Content-disposition: attachment" slapped on. Is there a way to do this with just client-side Javascript?
