Question

What are the specific disadvantages (if any) of dynamically including the CSS and JS files for a website?

By dynamically, I mean, using the document.write() method generate and tags.

I’d like to use this technique on a very large, high-traffic website, since it allows me to easily manage which files are downloaded for which site sections, and to switch on a compressed mode in which only minified files are downloaded.

Thoughts?

Answer 1

1. Reliability. People may have JS
   disabled, etc.
2. Debugging. Some browsers (IE) don’t
   give you the included file’s line
   number on an error, but simply the
   document.write line in the main file.
