title: Rendering iframe with dynamic link using jade
body: <p>I have a .jade view that contains this:</p>
  
  <pre><code>iframe(width='800', height='166', scrolling='no', frameborder='no', src= srcStr)
  </code></pre>
  
  <p>And I try to render it using an input source url from the user by doing this:</p>
  
  <pre><code>var string = req.body.code;
  res.render('embedview', { srcStr: string});
  </code></pre>
  
  <p>Now, the rendered page will just show an iframe without any content, even though the iframe code looks correct (with a src="..." attribute) when I view its source. Almost seems like it first loads the iframe with src="" and then pastes the source url in without reloading.</p>
