* Updated 7-02-2007. Refined code.

* Updated 3-27-2006. Added error message for browsers which do not support the XMLHTTP object.
The division below, with the ID of "theExample" was loaded as follows <script>include('latin.htm','theExample');</script>. Since JavaScript does not have a native include function, you will need to include a short JavaScript file in the head section of your page. <script type="text/javascript" src="include.js"></script>. The code for include.js is listed below and can be downloaded as a zip archive [here].
Note: [Full Article] You are also not
restricted to using this function on page load. It may be called anytime from any event. For example;
<a href="#" onclick="include('latin.htm','theExample');">Click Me to Load</a>.
