如何在DELPHI下用WEBBROWSER对网页中的TEXTAREA进行赋值？

我想在DELPHI下用WEBBROWSER对以下网页中的TEXTAREA进行赋值   <tr class="TableControl">
      <td class="TableData" colspan="2">
<textarea name="CONTENT" rows="8" cols="60"></textarea>
<script type="text/javascript">//<![CDATA[
window.CKEDITOR_BASEPATH='/module/editor/';
//]]></script>
<script type="text/javascript">//<![CDATA[
window.HTML_MODEL_TYPE='03';
//]]></script>
<script type="text/javascript" src="/module/editor/ckeditor.js.gz?t=B5GJ5GG"></script>
<script type="text/javascript">//<![CDATA[
CKEDITOR.replace('CONTENT', {"model_type":"03","width":"100%","height":"320","toolbar":"Default","language":"zh-CN"});
//]]></script>
      </td>
    </tr>
