Can anyone advise on the best approach please for setting up Google Analytics goal tracking for enquiry forms which are opened and posted using AJAX, all without any URL changes?

 

I could use an onclick Goal event to track clicks for the Submit button, but then this would also count those who might've had a validation issue when clicking the button.

 

To me it seems the ideal approach is to tweak the setup of the forms to make it post to a separate URL for the success/thank you message - that way I can then track form submission volumes effectively in GA Goals.

 

Before I go down this rather time consuming route (as there are amy forms that would require this), does anyone have any alternative suggestions please?

Could you use a hidden input field that has a tracking reference within it that posts only when the form is submitted correctly and track it this way?
