Question

I am calling the Google Analytics _trackEvent() function on a web page, and get back an error from the obfuscated Google code. In Firebug, it comes back “q is undefined”. In Safari developer console: “TypeError: Result of expression ‘q’ [undefined] is not an object.”

As a test, I have reduced the page to only this call, and still get the error back. Besides the necessary elements and the standard Google tracking code, my page is:

<script>
  pageTracker._trackEvent('Survey', 'Checkout - Survey', 'Rating', 3);
</script>

Results is that error.

What’s going on here?

This problem seems to occure when the page is not fully loaded yet: http://www.google.com/support/forum/p/Google+Analytics/thread?tid=4596554b1e9a1545&hl=en

The provided solution is to wait for pageTracker.cb

function trackEvent(target, action, opt_label, opt_value) {
  if(pageTracker && !pageTracker.cb) {
    setTimeout(function() {
      trackEvent(target, action, opt_label, opt_value);
    }, 200);
    return;
  }
  pageTracker._trackEvent(target, action, opt_label, opt_value);
}
