title: Get clicked element's HTML using Javascript
body: <p>I am adding a class to the clicked element and getting the innerHTML of it, if the clicked element is a container. But if it is a HTML element and not a container, 
  For eg., if the clicked element is an image <code>&lt;img src="hello.png" /&gt;</code>(which is not a container and cannot use innerHTML), then i need to get the corresponding element tag, i.e. i need to get <code>&lt;img src="hello.png" /&gt;</code>. So anyway to do this with pure JavaScript? </p>
  
  <p>P.S. I don't want to use any JavaScript libraries here.</p>
