<ec:table width="800" items="infomap" var="infoForm" rowsDisplayed="10" title="信息列表" sortable="true">
<ec:row>
<ec:column property="id" title=" "><input type='checkbox' value='${infoForm.id}' name='id'>${infoForm.id }</ec:column>
</ec:row>
</ec:table>
action:
request.setAttribute("infomap",ArrayList<infoForm> info...);
...
String id = request.getParameter("id");
这个String id 取出来是空,经过查找,发现 ec 里面的 checkbox value是空的缘故。再说,ec:column 后面一个${infoForm.id} 也是空,前面一个试过用 js alert测试过弹出来也是空值。求解
