jQuery Form Submission Parameter Check

Can I intercept/interrogate the form submission values using jQuery in the $(‘#formid’).submit(function() { }); call? I can’t check the value from the page as it’s the particular submit button pressed that I need to check. I’ve found this http://geekswithblogs.net/renso/archive/2009/09/09/intercept-a-form-submit-with-jquery-and-prevent-or-allow.aspx and it works in FF, but not in IE8, so that doesn’t help, unfortunately. I also don’t want to have to attach submit code to the buttons as I was hoping to make a generic bit of code I could plug into a whole set of forms.
