title: jQuery selector for select elements with empty value attributes?
body: <p>I'm using the below selector to get all the form inputs that are pre-populated with a value.</p>
  
  <pre><code>$('input[value!=""]');
  </code></pre>
  
  <p>This works great and so I thought I could apply the same logic to my select elements using the following selector, though it seems to be selecting all the select elements in Chrome.</p>
  
  <pre><code>$('select[value!=""]');
  </code></pre>
  
  <p>Below is an example of two types of selects on the form:</p>
  
  <pre><code>&lt;select name="phone2_type" id="phone2_type"&gt;
    &lt;option value=""&gt;Select one:&lt;/option&gt;
    &lt;option value="HOME"&gt;Home&lt;/option&gt;
    &lt;option value="CELL"&gt;Cell&lt;/option&gt;
    &lt;option value="BUSN"&gt;Business&lt;/option&gt;
  &lt;/select&gt;
  
  &lt;select name="state" id="state"&gt;
    &lt;option value=""&gt;Select one:&lt;/option&gt;
    &lt;option value="XX"&gt;Outside USA/Canada&lt;/option&gt;
    &lt;option value="AL" selected="selected"&gt;Alabama&lt;/option&gt;
    &lt;option value="AK"&gt;Alaska&lt;/option&gt;
    ...
  &lt;/select&gt;
  </code></pre>
  
  <p>I'd like to select the second select since it has a value selected already with the select="selected"</p>
