title: jQuery remove email in textarea
body: <p>I have HTML textarea.</p>
  
  <pre><code>&lt;textarea&gt; ... &lt;/textarea&gt;
  </code></pre>
  
  <p>I don't want users to enter any email address in the textarea. What is the best approach on this using jQuery? How to remove email entered before submitting the form? </p>
  
  <p>I only need hint and references. Thanks.</p>
