formating textfield input
<p>I've a text field.
I'm to type the email in it.. eg. username@domain.com</p>

<p>What I want is that, as soon as the user types the char "@", the remaining part of the string gets masked so that it appears to the user viewing as username@<strong><em>*</em>***</strong></p>

<p>But in the backend, the real keys typed has to be captured somehow.</p>

<p>Is there a way to do that using javascript??</p>
