Why don't you simply return true/false from your foo() function instead of
forcing the "return false" in your attribute?  Then return true if the
browser fails getElementById (or any other test), and return false if the
function succeeds:

<a href="foo.html" onclick="return foo()" onkeypress="return foo()">

function foo() {
  if (!document.getElementById) { return true; }
  // blah blah blah
  return false;
}

HTH,
