页面实现根据某个字段降序升序排序

前台页面

<form id="pagerForm" method="post" action="${ctx}/user/list" onsubmit="return navTabSearch(this)"> 
    <input type="hidden" name="orderField" value="${page.orderField}" />
</form>

<th orderField="strAccount">工号</th>

后台mapper里：

<choose>
      <when test="orderField!=null and orderField!=''">
        order by ${orderField} ${orderDirection}
      </when>
      <otherwise>
        order by createDateTime desc
      </otherwise>
 </choose>
