title: Get data from object based in key in data attribute
body: <p>When <code>data-person</code> has a value of <code>80</code> I want to show the content that is in the object with the matching key, ie. to access <code>{ "name": "Jhon Doe"}</code> and show in the HTML.</p>
  
  <pre><code>&lt;div id="people" data-person="80"&gt;&lt;/div&gt;
  </code></pre>
  
  <pre class="lang-js prettyprint-override"><code>var people = {"80": { "name": "Jhon Doe"}}
  var obj = JSON.parse(people);
  </code></pre>
  
  <p>How I can get this? Thank You!</p>
