Say you had the following HTML:

<input type="text" id="textbox"/>

<span>http://twitter.com/<span id="changeable_text"></span></span>

Your JS would listen for the keyup event.

$('input#textbox').keyup(function() {
//perform ajax call...
$('#changeable_text').text($(this).val());
});

Just attach to the keyup event of that textbox and update a span accordingly.

The textbox and span

<input type="text" id="txt-url-suffix" />
<div>Your public profile: http://www.twitter.com/<span id="url-suffix" /></div>

And some simple jQuery

var $urlSuffix = $("#url-suffix");
$("#txt-url-suffix").keyup(function() {
var value = $(this).val();
$urlSuffix.text(value);
});
