You need the open methond of the request object outside of the callback function as follows, and lastly you'll call the send method, we assign a callback function to the event of onreadystatechange, so that when the state changes and it happens to be done, we'll run some code. In the open method we especify what we are going to pass over the http protocol, we'll pass 2 parameters, the http method, an the path or resource. Hope this helps.

   var request = new XMLHttpRequest(); 
   request.onreadystatechange = function () {
      if (request.readyState === 4) {
         document.getElementById("footer").innerHTML = request.responseText;
      }
   };
   request.open('GET', 'footer.html'); 
   request.send();
