How to split  E-mail address from a text?
<p>In a text box, I keep E-mail addresses.
for example </p>

<pre><code>Text_box.value="a@hotmail.com,b@hotmail.com,c@hotmail.com"
</code></pre>

<p>How can I split all of the email addresses? Should I use Regex?</p>

<p>Finally, I want to keep any E-mail address which is correctly coded by user</p>
