Javascript onsubmit() doesn't fire WTF?

[GilBates]

I was kind of expecting to see a "test" message pop up when I clicked the submit button, but NNNNOOOOOOOOOOO! wtf gives?

<form method="post" onsubmit="javascript:window.alert('test');" action="http://www.botworks.com/local/BWIForm.pl" target=_blank name="BWIForm" >
<input type=hidden name="BWI_last_mode" value="review">
<input type=hidden name="BWI_action" value="Search">
<select name="BWI_table_name">
<option value="book">book
<option value="Content">Content
... lots more options here...
<option value="UserClass">UserClass
<option value="VolunteerProfile">VolunteerProfile
</select>
<input type=submit value="ReFORM&trade;">
</form>

<form onbeforesubmit="alert('test');">

<form onbeforesubmit="alert('test');">

Does onbeforesubmit exist? Or is it IE only?

I think the onsubmit is fine too.

<form ... onsubmit="return test()">

and test() would contain alert, etc.
