Capture onclick event on the Download Link of a File Browse Item

Question

I'm using APEX 4.0.1 and need to create a javascript:popupURL after a file browse item's onClick event fires and before the download dialog popup appears.
Here's a related thread: {thread:id=2135877}
Is this possible to do? If so, any help will be appreciated.

I tried each of the following in the the Element HTML Form Element Attributes for the File Browse item:
onClick=javascript:alert(this.value);
onClick=javascript:popupURL('http://www.google.com');
onFocus=javascript:alert(this.value);
onChange=javascript:alert(this.value);And what happened?
[A few points on good practice:
1. In the XHTML normally used in APEX 4.0 mark-up, all XHTML, including attribute/event handler names, should be in lower case: <tt>onclick</tt>, <tt>onfocus</tt>, <tt>onchange</tt>...
2. Attribute values should always be quoted.
3. The <a href="http://crisp.tweakblogs.net/blog/313/the-useless-javascript-pseudo-protocol.html">"javascript:" pseudo-protocol is evil</a>. There are a few places in APEX where we may have to resort to using it as URL is all we're offered to work with, but it's always better to use an event handler of some kind, either inline or (better) registered dynamically at runtime following the principles of <a href="http://en.wikipedia.org/wiki/Unobtrusive_JavaScript">unobtrusive JavaScript</a>. +It absolutely should not be used in inline event handlers.+
So:
{code}
onclick="alert(this.value);"
etc
