To clarify: you will write JavaScript code in your page which makes an asynchronous request to the back-end (Perl) server as the user does various things. It is often the case that the back-end will format a chunk of HTML (using some kind of template system) and then send back that HTML as part of a (JSON-encoded) response. This HTML is then inserted into the "innerHTML" of something on the screen. There is actually a tremendous amount of material out there on so-called "AJAX," for every programming language under the sun. "w3schools" even has on-line "try it!" demonstrations. Once you get the hang of what it is you are needing to do, "doing it in Perl" is straightforward.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
