title: Vaildate information inside TEXTAREA via jQuery / JS
body: <p>I have the following textarea value:</p>
  
  <pre><code>&lt;textarea name="field" id="field" rows="5" class="form-control"
  placeholder="Describe your guests" required=""&gt;
  Checkin(dd.mm.yyyy): 29.07.2015
  Checkout(dd.mm.yyyy): 30.07.2015
  Last Name: Johnson
  First Name: James
  Date of birth(dd.mm.yyyy): 12.12.1995
  Country Code: ISR
  Passport Number: 150150150
  Visa: Type D 1520 or Visa:
  &lt;/textarea&gt;
  </code></pre>
  
  <p>I want to vaildate the Checkin information, Checkin(dd.mm.yyyy): has to be dd.mm.yyy otherwise throw an error, Country Code: has to be 3 digits all uppercase for example? I know it is much easier to vaildate each field individually. I need to vaildate pieces inside the textarea.. preferably via jQuery. Any suggestions? </p>
