而且點(diǎn)出某一個(gè)學(xué)生信息的時(shí)候沒(méi)有生日，點(diǎn)擊也不會(huì)出現(xiàn)小日歷可以選擇，有哪位高手幫忙看看，謝謝。

你那個(gè)頁(yè)面里這么寫
<tr>
? ? <td>出生日期：</td>
? ? <td><input name="birthday" type="text" id="control_date" size="20"
? ? ? maxlength="10" onclick="new Calendar().show(this);" readonly="readonly" />
? ? </td>
? </tr>
action里 ?前臺(tái)傳過(guò)來(lái)的格式是這樣的：yyyy-MM-DD
做一個(gè)類型轉(zhuǎn)換
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd" );?
Date date = format.parse(birthday);
stu.setBirthday(date);
