title: Jquery - Disabling text field and re enabling fields
body: <p>Is there a jquery function to limit one submission on a text field once it has been submitted? And once the user deletes the existing information in that field should they change their mind, the submit button will become re enabled and they will be able to resubmit their text.</p>
  
  <p>For example:</p>
  
  <p>-User is making a tshirt
  -Tshirt product only allows one line of text on it
  -Once they insert text in the field, the field is disabled
  -Field can be reenabled if they delete or reset text field.</p>
  
  <p>Thanks in advanced!</p>
