## 场景 ##

使用EL表达式获取循环的list中的某个元素的值。

## 实现 ##

直接通过\[\]加下标获取。

${item.flightResult[0].defaultCabin.singlepriceAdt+item.flightResult[0].defaultCabin.taxAdt}

完整示例代码：

<c:forEach items="${data.resultInfo}" var="item">
                               <li class="ezmAll leaveTimeAll  border bor_gray_ddd ovh pa_2em mt_1em" >
                                <table width="100%">
                                <c:forEach items="${item.flightResult}" var="flight">
                                
                                 <tr>
                                  <td>
                                   
                                       
                                             <h3 class="text_14em c_gray_333 line_h_18em"><i class=" mr_02em"></i>${flight.airlinename}${flight.flightNo}</h3>
                                                     
                                  </td>
                                  <td>
                                   
                                            <tt class="fl text_al_r">
