title: jquery + read multiple img src
body: <p>I have around 8 img src tags that start like this:</p>
  
  <pre><code>&lt;img src="" id="joinCityResponse" class="joinResponse"/&gt;
  </code></pre>
  
  <p>If a related question is answered correctly then jQuery adds in the src field.
  <code>src="http://www.staticimages.co/dating/online-dating-index/join_tick.png"</code></p>
  
  <p>At the end of the 8 questions I have a Join Now button and I need to be able to know if all the questions have been answered correctly. eg: have the above src url set.</p>
  
  <p>How can I use jQuery to check all img tags with the class 'joinResponse' have the scr as set above? </p>
