title: Changing value of droplist based on the value of another dropdown list
body: <p>I need to change the selected value on a drop-down list(2) based on the value of the drop-down list(1). I had read a lot of posts but I can't find a solution.</p>
  
  <p>Drop-down list(1)</p>
  
  <pre><code>&lt;select name="Active" id="Active" class="imaindatesel"&gt;
      &lt;option value="" &lt;?php if (!(strcmp("", $row_SeqUpdate['SeqActive']))) {echo "selected=\"selected\"";} ?&gt;&gt;Select........&lt;/option&gt;
      &lt;option value="1" &lt;?php if (!(strcmp(1, $row_SeqUpdate['SeqActive']))) {echo "selected=\"selected\"";} ?&gt;&gt;Enabled&lt;/option&gt;
      &lt;option value="0" &lt;?php if (!(strcmp(0, $row_SeqUpdate['SeqActive']))) {echo "selected=\"selected\"";} ?&gt;&gt;Disabled&lt;/option&gt;   
  &lt;/select&gt;
  </code></pre>
  
  <p>Drop-down list(2)</p>
  
  <pre><code>&lt;select name="Client" class="imaindatesel" id="Client"&gt;
      &lt;option value="" &lt;?php if (!(strcmp("", $row_SeqUpdate['ClientName']))) {echo "selected=\"selected\"";} ?&gt;&gt;Select........&lt;/option&gt;
      &lt;option value="1" &lt;?php if (!(strcmp(1, $row_SeqUpdate['ClientName']))) {echo "selected=\"selected\"";} ?&gt;&gt;Enabled&lt;/option&gt;
      &lt;option value="0" &lt;?php if (!(strcmp(0, $row_SeqUpdate['ClientName']))) {echo "selected=\"selected\"";} ?&gt;&gt;Disabled&lt;/option&gt;  
  &lt;/select&gt;
  </code></pre>
  
  <p>Is there some way of doing this using jQuery?</p>
  
  <p>Many thanks in advance for your time.</p>
