title: Find all link in a div element and disable them all
body: <p>Assume that I have some HTML elements like these :</p>
  
  <pre><code>&lt;div id="content_div"&gt;
      &lt;span&gt;&lt;a href="some_link"&gt;Click me&lt;/a&gt;&lt;/span&gt;
      &lt;div&gt; Hello everybody. Click &lt;a href="some_link_else"&gt;me&lt;/a&gt; to do something else&lt;/div&gt;
  
      &lt;a href="3rd_link"&gt; Oops &lt;/a&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>All that I need is get all "a" tags in the #content_div and disable all of them (I don't want user to click on them). How could I do that in Jquery?</p>
