Views exposed filter autocomplete weird function() code
I do not think it is a major problem.  I had a similar problem a while back ( I don't remember how I cleaned it up :( ).  I would recommend you do check on another browser, but also try running update in the URL  (example.com/update.php) this script makes certain that all DB updates of  modules are completed.  If it persists, you may want to visit the Views issues site at Drupal.org.

Please post back on this page with what worked.
