form里面:


<tr class="tr_data1">
  <td>公司名称</td>
  <td><select name="companyName" size="1" style="position:absolute; left: 237px; top: 85px; width: 220px; height: 20px;
  clip: rect(0 237 18 200)" onchange="changeValue();" onclick="checkValue();" >
  <%
  for(Iterator iter = list.iterator(); iter.hasNext(); ) {
  piv = (PropertyInfoView)iter.next();
  %>
  <option value="<%=piv.getId() %>"><%=piv.getCompanyName() %></option>
  <%
  }  
  %>
  </select><input type="text" size="35" id="company_name" name="company_name" style="position:absolute; left: 237px;  
  top: 85px; width: 220px; height: 18px" onclick="checkInputValue();" onkeyup="getD(this.value);"></td>
  <div id="dvContent" style="display:none;position:absolute"></div>
  
</tr>
