遇到该错误，现在还没有解决。。。

原文如下：
    <td valign="top " align="center">
 <br  />
 <html:form   action="studentAction.do?action=0"  onsubmit="return checkEmpty(studentForm)">
 
   <table width="659" border="2" align="center" cellpadding="2" cellspacing="2">
        <tr>
          <td width="227" height="70" align="center" valign="middle"><div   align="center "    style="height:30; font-size:24px; color: #0000FF; text-align: center;" >学 &nbsp;&nbsp;&nbsp;号</div></td>
          <td width="410">
          <!input name="sno" type="text" id="sno"   style="height:35; width:400; font-size:24px" />        
     <div align="left">
             <html:text property="sno"></html:text>
          </div>
     </td>
        </tr>
        <tr>

        </tr>

    <div align="left">

          </div>
    </td>
        </tr>
      </table>
        <table  align="center"width="659" height="50" border="1" cellpadding="1" cellspacing="0">
          <tr>
            <td align="center"><p>&nbsp;

          </tr>
        </table>

    </html:form>

解决了：onSubmit 中的S 需要小写。
