                    <td>
                        <input type="submit" value="注册">

                </tr>
            </table>
        </form>

查了一下资料，原因是在 <form action="zhuche" method="post"> 执行onclick，所以每次页面都会刷新一次。
有两种方法，不用刷新页面

1、不用 <form action> 格式，删掉这个格式

2、改成 onclick="return resetClick()" ,其中resetClick()为onclick方法，并且在方法中 return = false；这样就不用刷新页面了
