title: onchange event show all text values of target element, why?
body: <p>Consider this:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
     &lt;script src="http://code.jquery.com/jquery-1.11.0.min.js"&gt;&lt;/script&gt;
     &lt;script&gt;
  
        $(function(){
  
             $("select").change(function(){
  
                   var val = $(this).val();
                   var text = $(this).text();
  
                   // That's fine
                   alert(val);
  
                   // But it's not. It alerts both Value 1 and Value 2
                   alert(text);
             });
        }); 
  
     &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
   &lt;select&gt;
      &lt;option value="val_1"&gt;Value 1&lt;/option&gt;
      &lt;option value="val_2"&gt;Value 2&lt;/option&gt;
   &lt;/select&gt;
  
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>When <code>onchange</code> event occurs, then it alerts the right value of target <code>option</code> element (val_1 or val_2). That's fine.</p>
  
  <p>But the problem with options's text. That should alert either Value 1 or Value 2, but not both! So what's the problem? Why it alerts both values, when only one target option element is processed?</p>
