title: jQuery removes textarea placeholder when clearing textarea text
body: <p>I have a Bootstrap modal with a textarea in it.  When you open the modal, the textarea needs to be cleared of any previous text so it's fresh every time you open it.</p>
  
  <p>The problem is, the placeholder on the field is also removed the first time you clear the text.</p>
  
  <p>I am using <code>$('textarea').val('')</code> to clear the text.</p>
