title: Get the value of select tag jQuery
body: <p>I have a code like </p>
  
  <pre><code>&lt;select id="sel1"&gt;
      &lt;option label="l1" value="1"&gt;Cool&lt;/option&gt;
      &lt;option label="l2" value="2"&gt;Hot&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>Now I want to get the value should be either Cool or Hot while changing the value of selected item in jQuery.
  I am trying by <code>querySource = $("#querySource").val();</code> but this is showing as <code>1</code> or <code>2</code>.</p>
  
  <p>How to do that?</p>
