title: How can I access object properties containing special characters?
body: <p>I have a <code>form</code> DOM element:</p>
  <pre><code>var virDom = document.getElementsByTagName(&quot;form&quot;)[0];
  </code></pre>
  <p><code>virDom</code> has two fields with IDs <code>creditId</code> and <code>pwdId..</code>. I can access <code>virDom.creditId</code>  without any issue, but <code>virDom.pwdId..</code> is failing with a syntax error, because of the periods contained in the name.</p>
  <p>How can I access such properties?</p>
