10,977 PointsA Simple AJAX Example (Problem)
Hi. I was trying to follow the AJAX Exercise. I checked my code and refresh the webpage for the result. It doesn't look the same as Dave did. There is no welcome message in webpage. Just only the headline. What is wrong with code or workspace? Thank you so much!

<script> //create an XMLHttp Request Object var xhr = new XMLHttpRequest();
Hope this helped...
