$.getScript, possible to give included script an id?

Question

Via jquery's $.getScript method, can you give the included script a DOM id?

So generated code should be:

<script type="text/javascript" id="xxxxxx" src="..."></script>

I know I could probably just document.write that line myself, but $.getScript must be there for a reason right? (cross browser compatibility, etc?)

document.write would be used before the DOM is ready. Usually jQuery methods are called after the DOM is ready. You probably meant you could just use `document.createElement("script")` — Ruan Mendes, Jun 30 '11 at 17:41
Out of curiousity what is the purpose of adding an ID to a dynamically loaded script? — Jamie Treworgy, Jun 30 '11 at 17:44
Why would you do that? What purpose does it serve? The script will already have executed. It won't have any effect on objects that have been created. http://jsfiddle.net/ueFn3/ If you want to free memory, this isn't how to do it. — Jamie Treworgy, Jun 30 '11 at 18:14
I'm using it to load a third party javascript, and in the source they seem to reference their own script by the id, that's why I needed to set it. I've now gone ahead and used the same snippet that google analytics uses (async) (no jquery) — , Jun 30 '11 at 18:19
Bizarre. I can't imagine why that would ever be necessary. It's not actually referencing "itself", it's just referencing some text between two script tags. Sounds like some kind of atrocious hack. — Jamie Treworgy, Jun 30 '11 at 18:22
I've just taken a look, it seems to reference it to get a hold of the src attribute, so that it can look at ? query parameters (via regex.test).. Can't it just look at window.location itself? — , Jun 30 '11 at 18:27

I think this has maybe been answered/discussed before here: Why call $.getScript instead of using the <script> tag directly?.

getScript allows you to dynamically load a script in situations where it's either desirable to delay the loading of the script, in situations where you want to get a status callback on when the script has been loaded or in situations where you couldn't use a script tag.

getScript has some downsides in that it's subject to the same-origin policy whereas a script tag is not.

If have seen other web pages put an ID on a script tag (smugmug.com), but I've also seen that flagged as non-standard when testing standard's compliance. It seems to work and be used by others, but I'm guessing it isn't standard.
