R – Google analytics page name

This can now be done in Chrome, Safari, Firefox 4+, and Internet Explorer 10pp4+!

See this question's answer for more information: Updating address bar with new URL without hash or reloading the page

Example:

 function processAjaxData(response, urlPath){
     document.getElementById("content").innerHTML = response.html;
     document.title = response.pageTitle;
     window.history.pushState({"html":response.html,"pageTitle":response.pageTitle},"", urlPath);
 }

You can then use window.onpopstate to detect the back/forward button navigation:

window.onpopstate = function(e){
    if(e.state){
        document.getElementById("content").innerHTML = e.state.html;
        document.title = e.state.pageTitle;
    }
};

Use Google Analytics hitCallback

You can specify a custom callback function on the tracker object.

_gaq.push(['_set', 'hitCallback', function(){}]);

The callback is invoked after the "hit is sent successfully."

If you want to track a click on a submit button and send the form afterwards you can use the following code (uses jQuery) for your event:

var _this = this; // The form input element that was just clicked
_gaq.push(['_set','hitCallback',function() {
    $(_this).parents('form').first().submit(); // Submit underlying form
}]);
_gaq.push(['_trackEvent', 'My category', 'My action']);
return !window._gat; // Ensure that the event is bubbled if GA is not loaded

Or as onclickone liner for your <input type="submit"> element:

onclick="var _this=this;_gaq.push(['_set','hitCallback',function(){$(_this).parents('form').first().submit();}]);_gaq.push(['_trackEvent','My category','My action']);return !window._gat;"

What it does it that it tracks the event My category/My action, uses jQuery to find the underlying form element of the submit button just pushed, and then submits the whole form.

UPDATE If you're using modern analytics.js code with ga() function defined, you can write this as following:

var _this = this;
ga('send', 'event', 'My category', 'My action', {
    'hitCallback': function() {
        $(_this).parents('form').first().submit();
    }
});

return !window.ga;
