title: Reset textarea height in javascript
body: <p>I have a textarea (auto resizing) and I want to clear all of its contents including its height.</p>
  
  <p>So far I've tried:</p>
  
  <pre><code>document.getElementById('textarea').value = '';
  </code></pre>
  
  <p>And :</p>
  
  <pre><code>document.getElementById('textarea').attribute('rows','1');
  </code></pre>
  
  <p>But both doesn't work.</p>
  
  <p><strong>EDIT :</strong> </p>
  
  <p>I use autosize.js with this :</p>
  
  <pre><code>&lt;textarea id="post" rows="1" title="Write something..." name="posttxt" placeholder="Write something..." role="textbox" autocomplete="off"&gt;&lt;/textarea&gt;
  </code></pre>
