title: Removing blank lines from textarea with jQuery
body: <p>First, I've tried all possible solutions that I've found here or Google, but no one seems to work for me.</p>
  
  <p>To be clear, I need to remove every empty lines from a text area. 
  This is what I've done so far:</p>
  
  <pre><code>&lt;textarea name="text" class="form-control" rows="14" id="text" placeholder="Here goes our query" &gt;&lt;/textarea&gt;
  
  
  $(document).ready(function () {
      $('#text').focusout(function () {
          var text = $('#text').val();
  
          text.replace(/(\r\n|\n|\r)/gm,"");
  
          alert('done');
      });
  });
  </code></pre>
  
  <p>I get successful alert on end, but those empty lines are still there. Is regexp correct ?
  My knowledge for js is not that big, so I need help :(</p>
