If you need to pass the JS param value to the url (as you have it in your code) you can try one of the following:

window.frames[navigationframe].location = window.frames[navigationframe].location +      "&param1" = + param1;   

or

document.getElementById(navigationframe).src = document.getElementById(navigationframe).src + "&param1" = + param1;

If this is the only variable you will be "passing" to the QueryString then make sure you format the QueryString properly (if it is the second or N+1 variable prepend '&' if it is the first prepend '?')
