Add dynamic text (while the user writes) inside label
<p>In a form Im trying to add some dynamic text, while the user writes:</p>

<pre><code>&lt;label for="signup_username"&gt;Username&lt;/label&gt;
&lt;input type="text" value="" id="signup_username" name="signup_username"&gt;
</code></pre>

<p>For example if user type "JOSOROMA" then the dynamic text inside label "signup_username" will reflect:</p>

<pre><code>&lt;label for="signup_username"&gt;http://www.localhost.lh/josoroma&lt;/label&gt;   
&lt;input type="text" value="" id="signup_username" name="signup_username"&gt;
</code></pre>

<p>If user type "obama" then then the dynamic text inside label "signup_username" will reflect:</p>

<pre><code>&lt;label for="signup_username"&gt;http://www.localhost.lh/obama&lt;/label&gt;
&lt;input type="text" value="" id="signup_username" name="signup_username"
</code></pre>

<p>Thanks in advance.</p>
