title: Click a button made from div with JavaScript?
body: <p>In Google+, the button that is used to post a comment is made from a div:</p>
  <pre><code>&lt;div role=&quot;button&quot; id=&quot;:1vq.post&quot; class=&quot;d-s-r tk3N6e-e tk3N6e-e-qc&quot; aria-disabled=&quot;false&quot; style=&quot;-webkit-user-select: none; &quot; tabindex=&quot;0&quot;&gt;Post comment&lt;/div&gt;  
  </code></pre>
  <p>I think I can click it with:</p>
  <pre><code>document.getElementById(&quot;:1vq.post&quot;).click(); 
  </code></pre>
  <p>But it says that the element have no attribute <code>click</code>,  and I found that <code>onclick</code> is null. So how could I click the button with JavaScript?</p>
