NW_addFormValues() to the rescue = ) See the docs for this method in 
environ_core.js for details.

Here's the submit button of our form (whitespace added for clarity only) :

<input	type="submit"
	onclick="__data__.getData(
		'http://foo.com/bar.php?'+NW_addFormValues(this.form),
		someObj,
		"listenerFunc",
		["foo"], ["foo"], 
		"deep"
	);" />

The crux of this is to use NW_addFormValues() with a reference to a node in 
the form to construct the GET query string representing the form's current 
values. You will need to specify the target href yourself somehow, but that's 
not a problem (I assume?). Also, I can't imagine many situations in which 
you'll use a syntax like the above instead of a wrapper function of some 
kind, but there you have it.

Hope that helps.
