title: jQuery, select a dropdown item by exact value
body: <p>I found a snippet on the jQuery documentation about how to select an item in a dropdown menu.  </p>
  
  <pre><code>$(element).find("option:contains(" + value + ")").attr('selected', 'selected');
  </code></pre>
  
  <p>Now this kind of works, except when I have two menu items that are similar. If my menu contains  2, 22, 222 and I set value to 2, then the last one will be selected. How do I specify an exact match rather than a contains?</p>
