[semi-OT]simulating onSubmit in post

Hi folks,

I'm trying to teach myself how to GET and POST submissions to URLs  
that provide simple web services, like word lookups and the like. I  
understand the basic concept pretty well and can successfully  
"harvest" data from various web forms. But I notice that often POST  
method forms use JavaScript calls to validate data in the forms before  
submitting it to the server. It might look like this:
<form method="POST" action="someurl.htm?loadpage" name="formname"  
onSubmit="return Validate(this);">
In this case the Validate function is defined in the header and  
basically returns true if the submit came from the form "formname" AND  
all of the fields are filled in. It returns false if either of these  
conditions is not met.

My question: Is it possible to construct a post command and/or header  
combination that simulates this onSubmit event returning true? This is  
basically an academic exercise to help me understand how JS and forms  
work, and how Rev's GET and POST functionality works; I'm not planning  
to distribute stacks that do this in any way.
