title: Trigger jQueryUI datePicker on button click, send result to disabled input field
body: <p>I've been searching for a way to do this, but could not find anything  </p>
  
  <p>I want to have a:  </p>
  
  <ul>
  <li><p>Disabled input text field, called #XX. This input will store the selected value from datepicker (as this input is disabled I won't be able to use this to trigger the datePicker)</p></li>
  <li><p>Button, besides #XX. When user clicks this button, datePicker will show. User will select the date, and this date will be assigned to disabled input #XX. </p></li>
  </ul>
  
  <p>I want this so user can't change manually -by typing crap- the selected date</p>
  
  <p>Also, should I validate if date was entered using #XX.val()? or is there a better way?</p>
