页面传值不通过，请求帮助！
servlet总是获取不到页面的值，本来之前是一个JS控件，为了测试直接改为<INPUT>,可这样取到的还是都为空值，搞不明白
我是想取得页面的值传到数据库，如果取到的值为空，就会报无法将STRING转换为DATATIME，数据库传这种类型字符串“yyyy-MM-dd”是可以正确查询数据的
谢谢帮忙！
这是提交的页面，是没有问题的

这是SERVLET处理完毕后转向的页面

<td>查询日期： <input class="Wdate" type="text" name="starttime" id="d15" onFocus="WdatePicker({isShowClear:false,readOnly:true})"/>到 <input class="Wdate" type="text" name="endtime" id="d15" onFocus="WdatePicker({isShowClear:false,readOnly:true})"/> </td>
</tr> -->
<tr>
<td>查询日期： <input type="text" name="starttime" value=""/>到 <input type="text" name="endtime" value=""/> </td>
怎么有两个查询日期哦？
保留其中一个，如果用JS，你确定选择日期后，文本框中有值？
如果用下面一个，请把value=""去掉试试
还有提交method＝“post”，怎么在doGet里写哦
[解决办法]
改一下试试:<tr>
<td>查询日期： <input type="text" name="starttime" value="" id="starttime"/>到 <input type="text" name="endtime" value="" id="endtime"/> </td>
</tr>
<tr>
<td> <input type="submit" name="submit" value="提交"/> </td>
</tr>
