Link and execute

I am trying to link to an external webpage and then run a necessary javascript to view the correct list of information.

What I have tried to do is

<a href="http://www.iada.org/dotnet/iada_website/iadamembers.aspx" target="_blank" onclick="submitformUSAStateMap('OH')">IADA association page</a>
I want to view the Ohio list of companies, rather than navigating to just the map page. Any ideas?
