Get all values of array elements
<p>I have an array with HTML elements from a selector. Looks like this:</p>

<pre><code>var selection = $('.features_items');
// selection = [div.features_item, div.features_item];
</code></pre>

<p>The div looks like this:</p>

<pre><code>&lt;div class="features_item selected" value="2"&gt;
</code></pre>

<p>Now I want to get all values from the div's in the array: [2,3]</p>
