获取同一个class下的不同元素

<c:forEach var="item" items="${list}" varStatus="status"> 
     <tr class="tm-open">
       <td class="ids" itemid="${item[0]}">
         <input type="checkbox"  name="selid" value="${item[0]}" >
       </td> 
       <td align="center">${
     (selectIndex-1)*pageSize+status.count}</td><%-- ${
     item.guid} --%>
       <td align="center">${
     item[1]}</td>
       <td align="center"><div class="ellipsis" title="${item[2]}">${
     item[2]}</td> 
       <td align="center"><div class="ellipsis" title="${item[3]}">${
     item[3]}</td>
       <td align="center">
          <textarea class="textarea record-text content"  name="dutyperformance.accountAbilitystiution" id="${item[0]}">${
     item[4]}</textarea>
          <input type="hidden" name="dutyperformance.informationGuid" id="${(selectIndex-1)*pageSize+status.count}" value="${item[0]}" />

       </td>
    </tr>
    </c:forEach>
