title: Access Element when Extending prototype
body: <pre><code>Element.prototype.objProp = new function(){
      this.property = null;
  };
  </code></pre>
  
  <p>Right now what is null I want to set equal to element's ID. My main question is how to access the Element. Whenever I use <code>this</code> keyword it returns the object itself not the Element. What to do?</p>
