title: Getting all textareas inside a form, parse the contained text on a button click?
body: <p>I have a form with N textareas (each with a different name and id) and a button, which posts the form data. I want to check the content of all the N textareas for a certain pattern and only post to the form site after all patterns have been manually replaced. So, on button click I want to check all textareas for that pattern and show a window (like alert) in case there are still patterns present.</p>
  
  <p>How would I do that? Is it possible at all?</p>
  
  <p>Thanks!</p>
