title: Can you use "this" attribute on onclick of an HTML tag?
body: <p>Can you use the <code>this</code> tag for the onclick on an HTML tag?
  Here's my JS code...</p>
  
  <pre><code>function changeImage() {
      this/*&lt;-- right there &lt;--*/.src=a;
  }
  document.getElementsByTagName('img').onclick = function(){ 
      changeImage();
  } ;
  </code></pre>
  
  <p>Am I doing something wrong?</p>
