It will. Test it.

The URL to the current page may be, but the URL that is in the script
element is not. It will create an element and append it that looks
something like this:
<script type="text/javascript"
src="URLToFileOnServer.PHP?zipRaw_id.value></script>

There is no need to. But if you are getting data from the server by
creating Script Elements, you are using the wrong term for it. It is not
AJAX but rather it is Dynamically Loading Script Files. Search the
comp.lang.javascript archives for those words and my name, you will find
some interesting reading.

It is the right direction, if what I have read so far is what you are
trying to do.

And when you append that Script element to the page, and the server
returns information from the request, then the browser will attempt to
execute that data as script content.

I told you how.
Since I do not find the Original Message of this thread in
comp.lang.javascript it would help a lot if you posted to clj what you
are trying to do. It appears you are trying to do something like this:
Take the value of an input element.
Pass it to the server.
Have the server process some data based on that input value.
Return some data to the browser.
Have the browser process that data.
All without reloading the page.
And that is precisely what I told you how to do :)
