title: Find and list every element's id value
body: <p>I'm trying to get all the found elements within a <code>&lt;div&gt;</code>, but by default it stops when it found the first occurrence, but I want it to list every found element's <code>id</code> value.</p>
  
  <p>So this doesn't work:</p>
  
  <pre><code>listy = $("DIV").find("SPAN").attr("id");
  </code></pre>
  
  <p>I've been experimenting with <code>.get</code> and <code>.map</code>, but I think they're not what I want..</p>
