Adwords ExitApi.exit() with url parameters

[Benjamin van Rossum]

I have created a banner for Adwords, using HTML5 with a form element, which accepts some inputs.

The whole banner is not clickable, only the submit button, which I achieved by adding "onclick="ExitApi.exit()"" to the button.

Question: How do I add url paramaters to the ExitApi.exit(), like example.com/page?a=1&b=2&c=3 etc
