title: Suppress line feed in <textarea> on pressing enter [html, javascript]
body: <p>I want to suppress line feed in  on pressing enter. Instead, I want to submit the form. I know how to submit the form on pressing enter in textarea, but I don't know to supress line feed on pressing enter. I need to hide it from user, I mean I want user not to see that enter made new line even for a moment.</p>
  
  <p>Thank you in advance.</p>
