Google analytics _trackPageview callback

Is there a way to define a callback for w开发者_JS百科hen _trackPageview completes?

I have the following code to track when a user logs into my site, and to refresh the page afterwards:

pageTracker._trackPageview('/login/complete');
location.reload(true);

The problem with the above code is that _trackPageview attaches an image to the DOM and there's no guarantee that the image loads before the page refreshes.

Overwriting the current Image() function in the page is one solution:

  var oldImage = window.Image;
  window.Image = function()
  {
      var self = this;
      var theImage = new oldImage();
      $(theImage).load(function(){
          // Analytics ajax finished
          // Do something here (submit the form or whatever)
      });
      return theImage;
  };

But I actually think that Malvolio has a better solution using _gaq.push() that will work for what you need.

Most implementations I've seen get around this problem by putting the reload/redirect in a setTimeout() of 500ms-1s
