jquery calculate html values next to checked checkboxes
<p>My head is not thinking right today. Could any of you help? =)
Only checked int values in second column need to be calculated and alerted in sum.</p>

<pre><code>&lt;table width="100%"&gt;
  &lt;tr&gt;&lt;td&gt;Product Name&lt;/td&gt;&lt;td&gt;Price $&lt;/td&gt;&lt;/tr&gt;
  &lt;tr&gt;&lt;td&gt;&lt;input type="checkbox"&gt; Product 1&lt;/td&gt;&lt;td&gt;200&lt;/td&gt;&lt;/tr&gt;
  &lt;tr&gt;&lt;td&gt;&lt;input type="checkbox"&gt; Product 2&lt;/td&gt;&lt;td&gt;300&lt;/td&gt;&lt;/tr&gt;
&lt;/table&gt;
&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js" type="text/javascript"&gt;&lt;/script&gt;
&lt;script type="text/javascript"&gt;
  $('input').change(function() {
    var sum = 0;
    $("input:checked").each(function(){
      sum += parseInt($("input:checked").closest('td').next().html());
    });
    alert(sum);
  });
&lt;/script&gt;
</code></pre>

<p>Thanks.</p>
