"Tag" (like keyword tag) multiply e-mails in input with validation
<p>I am looking for a simple jQuery script that I can call on a input field.</p>

<p><strong>When user input e-mails in the field and then presses SPACE or ENTER it should tag the e-mail.</strong></p>

<p>Very simple, but haven't been able to find such a script. Does it exist?</p>

<p>NOTE: NOT this one: <a href="http://stackoverflow.com/questions/519107/jquery-autocomplete-tagging-plug-in-like-stackoverflows-input-tags">jQuery autocomplete tagging plug-in like StackOverflow&#39;s input tags?</a> - it doesn't really suit my needs. As you can enter other values than an e-mail (no validation) and also complicated integration. I was woundering for a: onKeyUp="function()" solution, or something similar.</p>
