title: How to pass two values in onChange
body: <p>So, I have a 2 select tags and during the
  onChange event of the second select tag; I want to pass the values of the 2 select tags</p>
  
  <pre><code>    &lt;td&gt;District:
      &lt;div&gt;
      &lt;select name="district" id="district" onchange="getZone(this.value)"&gt;
      &lt;option value="ALL"&gt;ALL&lt;/option&gt;
      &lt;?php
       include_once 'newcompute.php';
       $computation = new newcompute();
       echo $computation-&gt;getDistrict();
      ?&gt;
      &lt;/select&gt;
      &lt;/div&gt;
      &lt;/td&gt;
      &lt;td&gt;Barangay:&amp;nbsp;
  &lt;div id="barangay" name="barangay"&gt;
      &lt;select onchange="loadReport(barangay.value,district.value)"&gt;
  &lt;option&gt;Select a Barangay&lt;/option&gt;
  &lt;option value="ALL"&gt;ALL&lt;/option&gt;
  &lt;/select&gt;
      &lt;/div&gt;
  &lt;/td&gt;
      &lt;/tr&gt;
  </code></pre>
  
  <p>So, I tried doing the onchange="loadReport(barangay.value,district.value)" but I only get 
  a UNDEFINED value for district.value </p>
  
  <p>How do I get loadReport to pass the current selected value of select tag district?</p>
