    <tr>
     <td height="28"><input name="keyword" type="text" style="width:150px" id="keyword"/></td>
    </tr>
    <tr>
     <td height="28"><select name="Searchtype" style="width:110px" id="Searchtype" onchange="Searchtype1();">
      <option value="news" selected="selected">新闻中心</option>
      <option value="case">工程案例</option>
     </select>
     <input type="submit" name="Submit" value="搜索" /></td>
    </tr>
   </table>
 </form>
 <script language="javascript">
 function Searchtype1(){
 var type=document.getElementById("Searchtype").options[document.getElementById("Searchtype").selectedIndex].value;
 if (type=="news"){document.getElementById("form1").action="../news/index.asp"}
