关于struct2 datetimepicker的取值问题

Question

JSP：          
<sx:datetimepicker label="Project End Date"  name="project.project_enddate" displayFormat="yyyy-MM-dd"></sx:datetimepicker>action：
String result = this.request().getParemeter("project.project_startdate");
result始终为null求问为什么

Answer 1

String result = this.request().getParemeter("project.project_startdate");
改为
String result = this.request.getParemeter("project.project_startdate");

Answer 2

。在eclipse中根本都无法删掉那个括号

Answer 3

其它的parameter都能get到的，比如
<tr>
<td colspan="2"><s:textfield name="project.project_name" label="Project Name"/></td>
</tr>这个就是可以通过getParameter 来get到，为什么就是datetimepiker不可以

Answer 4

<sx:datetimepicker label="Project End Date"  name="project.project_enddate" displayFormat="yyyy-MM-dd"></sx:datetimepicker>action：
String result = this.request().getParemeter("project.project_startdate");你在开玩笑？看红色的东西，都不一致

Answer 5

说了看下你的action，你在磨磨唧唧的

Answer 7

不是说过
String timelimit = this.request().getParameter("project.project_startdate");
改为
String timelimit = this.request().getParameter("project.project_enddate");吗？
action直接
project.getProject_enddate()；没有值吗？
典型的struts封装对象的应用。

Answer 8

你为啥用这个，无语了，直接用mydate97不就好了，

Answer 9

 貌似 datetimepicker  是标签
