determine js filename from inside the file?

Hi,

Is there a way to determine the name of a JavaScript file from inside
the very same file?

Thanks,
Peter

No, I don't think so. Especially, on the Web there are no files.

document.all[document.all.length-1].src generally works for scripts
executed during loading in a progressive manner...

True, and other DOMs may provide the means with other host objects,
too (W3C DOM: var scripts = document.getElementsByTagName("script"),
scripts[scripts.length - 1]). However, that is _not_ determining
the filename, it is determining the URL of the script resource.

Of course it is, from a file html document where the only place
scripts are loaded from files. in http loaded it will be the URL
certainly.

One could have a script in a .js file attached to an HTML document find
its filename.
It could find the <script> tags on the HTML page, and find the src of
those. If there is only one ,js file then the .js file would know that
that must be itself, and then it would know its filename. If there are
more than one, I suppose you'd have to incrementally open each and
parse to see if the functions inside them are identical to its own. If
you had two
<script src="f1.js"> and <script src="f2.js">
in a page and f1.js was a duplicate of f2.js neither would be able to
disambiguate which of the twins it was, I think.
