title: Get tag name of clicked element inside cross domain iframe
body: <p>The idea is simple: popup the tag name of the clicked element. The <code>Javascript</code> code:</p>
  
  <pre><code>function inspect(event) { alert(event.target.tagName); event.preventDefault(); }
  </code></pre>
  
  <p>Then, in the HTML:</p>
  
  <pre><code>&lt;body onclick="inspect(event)"&gt;
  </code></pre>
  
  <p>The problem occurred when the clicked element is inside an cross domain <code>iframe</code>, for example the <code>iframe</code> source is Google.</p>
  
  <p>So what's the solution here? I've tried a lot but it was unsuccessful. If you have any solution, or work around way, please help me. Thanks a lot.</p>
