代码如下：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>我要注册</title>
<script type="text/javascript">
function resetClick()
{
}
</script>
</head>
<body style="text-align: center;">
<form action="zhuche" method="post">
<table width="40%" border="1">
<tr>
<td>用户名</td>
<td>
<input type="text" name="userName" id ="userName">
</td>
</tr>
<tr>
<td>密码</td>
<td>
<input type="password" name="userPwd" id="userPwd">
</td>
</tr>
<tr>
<td>确认密码</td>
<td>
<input type="password" name="confirmPwd" id="confirmPwd">
</td>
</tr>
<tr>
<td>
<!-- 执行重置 -->
<input type="reset" value="清空" onclick="resetClick()">
</td>
<td>
<input type="submit" value="注册">
</td>
</tr>
</table>
</form>
</body>
</html>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
