title: Select Option Value return Integer by default
body: <p>Is it has any way to get value from Select Option as Integer by default ?</p>
  
  <p>from select here</p>
  
  <pre><code>&lt;select id="lesson_per_class" &gt;
   &lt;option value=""&gt;&amp;nbsp;&lt;/option&gt;
   &lt;option value="1"&gt;1 Lesson&lt;/option&gt;
   &lt;option value="2"&gt;2 Lessons&lt;/option&gt;
   &lt;option value="3"&gt;3 Lessons&lt;/option&gt;
   &lt;option value="4"&gt;4 Lessons&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>When I tried to get their value to calculate, I found that it return as String and can't use to calculate here</p>
  
  <pre><code>var lesson_per_class = $('#lesson_per_class').val();
  alert('value is ' + ( 10 + lesson_per_class )); 
  // it give result as 10x instead of 1x 
  </code></pre>
  
  <p>currently, the way I solved is parseInt(), but I need to know, is it has anyway to get it as Integer by default?</p>
