title: Getting the option value without submitting a form
body: <p>I want to use the user selected option value without submitting a form. Here is my HTML code</p>
  
  <pre><code>Combo Box&lt;br&gt;
  &lt;select name="select1"&gt;
  &lt;option value="IVP" selected&gt;IVP&lt;/option&gt;
  &lt;option value="SURTEK"&gt;SURTEK&lt;/option&gt;
  &lt;option value="GUITARTUNER"&gt;GUITARTUNER&lt;/option&gt;
  &lt;option value="OTHER"&gt;OTHER&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I want to take the selected option value to a php variable, so that according to option value a new set of data could be displayed.
  Thanks</p>
